 "faqs": [
  {
   "q": "What is the biggest tire I can fit on a stock 2025 4Runner with no modifications?",
   "a": "On the SR5 or TRD Off-Road with factory 17″ or 18″ wheels, 285/70R17 (32.7″) or 285/70R18 (33.7″) fit without rubbing. You may want to remove the mud flaps for extra clearance at full lock. On the TRD Pro and Trailhunter with their +20mm offset wheels, 285/70R18 (33.7″) fits completely stock with mud flaps still installed. Some TRD Pro owners have fit 295/70R18 (35″) on stock suspension with zero rubbing."
  },
  {
   "q": "Do I need a body mount chop for 35s on the 6th Gen 4Runner?",
   "a": "No. Unlike the 5th Gen 4Runner, the 6th Gen does not require a body mount chop to fit 35-inch tires. The TNGA-F platform provides enough wheel well clearance that 35s can be achieved with a 2.5–3″ lift, crash plate/splash guard removal, fender liner repinning, and some bumper trimming. This is one of the biggest advantages of the new platform."
  },
  {
   "q": "Will 5th Gen 4Runner wheels fit the 6th Gen?",
   "a": "Not directly. The 6th Gen uses M14 lug nuts (vs M12 on the 5th Gen) and has a smaller center bore of 95.1mm (vs 106.1mm). You would need the wheels drilled to accommodate the new lug size. Most aftermarket wheel manufacturers now offer 6th Gen-specific options. Always verify specifications before purchasing."
  },
  {
   "q": "What wheel offset should I get for the 6th Gen 4Runner?",
   "a": "The community consensus is +25 to +35mm for the best balance of stance and clearance. Stock SR5/Off-Road wheels are +55mm, which is conservative. The TRD Pro and Trailhunter run +20mm from the factory. Going below +25mm creates significant rubbing issues and is not recommended unless you're prepared for extensive trimming. For most builds targeting 33–35″ tires, +35mm offers the cleanest fitment with minimal modifications."
  },
  {
   "q": "Can I run 35-inch tires on the TRD Pro without a lift?",
   "a": "Some TRD Pro owners have confirmed that 295/70R18 (approximately 35″) tires fit on stock suspension with +22mm offset wheels and zero rubbing, even at full steering lock. However, this is at the limit. If you plan to off-road with full suspension articulation, a 2–2.5″ lift is strongly recommended to prevent rubbing under compression. For on-road use, stock height may be sufficient."
  },
  {
   "q": "What's the difference between the 6th Gen 4Runner and 4th Gen Tacoma for tire fitment?",
   "a": "They share the same TNGA-F platform, so the front suspension geometry and wheel well dimensions are very similar. Tire fitment data from the 2024+ Tacoma is largely applicable to the 2025+ 4Runner, especially for the front. The 4Runner's rear is independent rather than a solid axle, so rear fitment differs slightly. Most owners find the 4Runner has equal or slightly better clearance than the equivalent Tacoma setup."
  },
  {
   "q": "Will a 35-inch spare tire fit under the 6th Gen 4Runner?",
   "a": "No. A 35″ spare will not fit in the factory underbody spare tire carrier due to both width and ground clearance issues. If you're running 35s, plan on a swing-out rear tire carrier (brands like Westcott, CBI, and others make them for the 6th Gen) or a roof-mounted spare. Some owners carry a smaller spare as a get-home solution."

 "content_markdown": "You just rolled off the dealer lot in a brand-new 2025 [Toyota 4Runner](/guides/the-toyota-4runner-evolution-of-an-off-road-icon-and-nevada-trail-master/). The factory rubber looks fine, but you know it can do better. Whether you're running trails outside Yerington, crawling Rubicon, or just want that aggressive stance in the Reno Costco parking lot, the first question is always the same: **how big can I go without tearing my rig apart?**\n\nWe dug through every 6th Gen 4Runner forum thread, verified fitment data from real owners, cross-referenced with the [4th Gen Tacoma](/guides/biggest-tires-that-fit-stock-3rd-4th-gen-toyota-tacomas-the-definitive-guide/) (which shares the TNGA-F platform), and compiled everything into one definitive resource. No guesswork. No \"it should fit.\" Just verified numbers.\n\n### ⚡ TL;DR: Quick Answers\n\n**SR5 / TRD Off-Road (17″ & 18″ wheels):** 285/70R17 (32.7″) or 285/70R18 (33.7″) fits on stock suspension with mud flap removal. No lift needed.\n\n**TRD Pro / Trailhunter (+20mm offset wheels):** 285/70R18 (33.7″) fits stock with zero rubbing, even at full lock with mud flaps on. 295/70R18 (35″) fits stock on some setups with no rubbing reported.\n\n**With 2–3″ lift:** 34″ tires fit comfortably on most trims. 35s fit with 2.5–3″ lift + crash plate/splash guard removal + front bumper trimming.\n\n**37s:** Possible with 3″+ lift, aftermarket UCAs, significant trimming, and aftermarket fender flares. [Westcott Designs](https://www.westcottdesigns.com/2025-4runner-parts-accessories/) has proven it on a pre-collar kit.\n\n## Stock Tire Sizes by Trim: What Toyota Ships From the Factory\n\nThe [6th Gen 4Runner](https://www.toyota.com/4runner/) comes in seven main trim levels, and tire/wheel combos vary significantly. This matters because your **starting point determines how much room you have** before you need modifications.\n\n| Trim | Wheel Size | Offset | Stock Tire | Diameter |\n| --- | --- | --- | --- | --- |\n| **SR5** | 17″ × 7″ | +55mm | 245/70R17 Yokohama Geolandar | 30.6″ |\n| **TRD Sport** | 20″ × 8″ | +55mm | 265/55R20 Yokohama Geolandar A/T | 31.5″ |\n| **TRD Off-Road** | 18″ × 7.5″ | +55mm | 265/70R18 Falken Wildpeak / Michelin LTX | 32.6″ |\n| **Limited** | 20″ × 8″ | +55mm | 265/55R20 Dunlop Grandtrek AT20 | 31.5″ |\n| **Platinum** | 20″ × 8″ | +55mm | 265/55R20 Dunlop Grandtrek AT20 | 31.5″ |\n| **Trailhunter** | 18″ × 8.5″ | +20mm | 265/70R18 Toyo Open Country A/T III | 33″ |\n| **TRD Pro** | 18″ × 8.5″ | +20mm | 265/70R18 Toyo Open Country A/T III | 33″ |\n\nNotice the offset split: the TRD Pro and Trailhunter run +20mm offset wheels (8.5″ wide), which pushes the tire outward for a wider, more aggressive stance. Every other trim runs +55mm offset. That difference is critical for fitment, it determines how much clearance you have at full steering lock and during suspension compression.\n\n## The Offset Factor: Why It Matters More Than Tire Size\n\nIf there's one takeaway from this entire guide, it's this: **offset determines fitment more than tire diameter.** You can stuff a 33″ tire on stock suspension, but if the wheel offset pushes the tire too far outboard, you'll rub on the fender liner, crash plates, and bumper at full lock.\n\n+55\n\nSR5 / OR / Sport  \nStock offset\n\n+45\n\nTRD 18″ upgrade  \nOEM accessory\n\n+25 to +35\n\nAftermarket sweet spot  \nBest balance\n\n+20\n\nPro / Trailhunter  \nFactory aggressive\n\nLower offset = more tire poke = more clearance issues. Anything below +25mm is aggressive and will likely require additional trimming. Community consensus says **+25 to +35mm is the sweet spot** for aftermarket wheels on the 6th Gen, it gives a noticeable stance improvement without forcing extensive modifications.\n\n## Biggest Tires on Stock Suspension: No Lift Required\n\n### On 17″ Wheels (SR5 or Aftermarket)\n\n| Tire Size | Diameter | Fits Stock? | Notes |\n| --- | --- | --- | --- |\n| 265/70R17 | 31.6″ | ✓ No rub | Direct bolt-on, no mods at all |\n| 285/70R17 | 32.7″ | ✓ No rub | Remove mud flaps on +55 wheels. Fits clean on +25–35 aftermarket |\n| 285/75R17 | 33.8″ | ⚠ Minor trim | Fits on +25mm offset wheels. Mud flap removal + splash guard removal recommended |\n| 295/70R17 | 33.3″ | ⚠ Minor trim | Wider footprint, needs +25–35 offset and crash plate removal |\n\n### On 18″ Wheels (TRD Off-Road, Pro, Trailhunter, or Aftermarket)\n\n| Tire Size | Diameter | Fits Stock? | Notes |\n| --- | --- | --- | --- |\n| 265/70R18 | 32.6″ | ✓ No rub | Factory size. Bone stock, zero issues |\n| 275/70R18 | 33.2″ | ✓ No rub | Slight gain in diameter and width. Easy upgrade |\n| 285/70R18 | 33.7″ | ✓ No rub | Confirmed on +25 offset with no lift. Nitto Ridge Grapplers verified at 33.9″ |\n| 295/70R18 | 34.3″ | ⚠ Trim needed | Fits TRD Pro stock on +22 offset (Rays TE37). May need mud flap + crash plate removal on other trims |\n\n### On 20″ Wheels (Sport, Limited, Platinum)\n\n| Tire Size | Diameter | Fits Stock? | Notes |\n| --- | --- | --- | --- |\n| 265/55R20 | 31.5″ | ✓ No rub | Factory size |\n| 275/60R20 | 33.0″ | ⚠ Check fit | Significant jump. May rub at full lock on +55 offset. Mud flap removal likely |\n| 285/55R20 | 32.3″ | ✓ No rub | Wider with similar diameter. Good upgrade for Sport/Limited |\n\n## Biggest Tires with a Leveling Kit (2–2.5″ Lift)\n\nA leveling or preload collar kit is the most popular first mod for the 6th Gen. Brands like Westcott Designs, Peak Suspension, ReadyLIFT, and Toytec all make bolt-on options that give you 2–2.5″ of front lift with 0.75–2″ in the rear, leveling the factory rake without replacing shocks or springs.\n\n| Tire Size | Diameter | Fits with Level? | Mods Required |\n| --- | --- | --- | --- |\n| 285/70R17 | 32.7″ | ✓ Easy fit | None. Clean clearance all around |\n| 285/75R17 | 33.8″ | ✓ Good fit | Remove mud flaps + splash guards. +35 offset recommended |\n| 285/70R18 | 33.7″ | ✓ Easy fit | None on +25 or wider offset |\n| 295/70R18 | 34.3″ | ✓ Good fit | Remove crash plates and splash guards. +22–35 offset |\n| 34″ (various) | ~34″ | ✓ Fits | Crash bracket delete, liner repin, splash guard removal. Possible minor bumper trim |\n\nThe consensus from the community is that **34″ tires are the sweet spot for a leveling kit** on the 6th Gen. You get noticeably more ground clearance and a dramatically more aggressive stance without cutting into your body panels.\n\n## 35-Inch Tires on the 6th Gen 4Runner\n\n35s on the 6th Gen are absolutely doable, and it's significantly easier than on the 5th Gen, where 35s required body mount chopping and extensive fabrication. The shared [TNGA-F platform with the Tundra](/guides/the-2-4l-turbocharged-i-force-4-cylinder-powering-the-new-toyota-tacoma-for-battle-born-adventures/) gives the 6th Gen considerably more wheel well real estate.\n\n### What You Need for 35s\n\n### Required Modifications for 35″ Tires\n\n-   **Lift:** Minimum 2–2.5″ front, 2″ rear (collar kit + rear spacers). Ideally 3″ for full off-road flex\n-   **Crash plate & splash guard removal:** Both sides, all four corners. These are bolt-on and reversible\n-   **Fender liner repin:** Push the felt liner back to create clearance. Use existing hardware\n-   **Front bumper trimming:** Roughly 1″ of material removed from the lower bumper edge. Conservative cut first, then adjust\n-   **Rear rocker/fender trim:** Minor trimming near the rear wheel well where the fender meets the rocker panel\n-   **Wheels:** 17×8.5 or 17×9 with +25 to +35mm offset (or 18×8.5 with +22 to +35mm). Avoid anything below +25\n\n**What you do NOT need:** No body mount chopping (unlike 5th Gen), no cab mount chop (same as [4th Gen Tacoma advantage](/guides/biggest-tires-that-fit-stock-3rd-4th-gen-toyota-tacomas-the-definitive-guide/)), no frame modifications. This is a huge improvement over previous generations.\n\n### Real-World 35″ Builds Verified\n\n| Build | Wheels | Tires | Lift | Rubbing? |\n| --- | --- | --- | --- | --- |\n| TRD ORP (MJMotorsports808) | Rays TE37 18×8.5 +22 | Mickey Thompson Baja Boss AT 295/70R18 | ReadyLIFT 1.5″ level | Minor, trimming done |\n| TRD Pro (Mudbath) | Rays TE37 18×8.5 +22 | Mickey Thompson Baja Boss AT 295/70R18 | Stock suspension | None, zero rub at full lock |\n| SR5 (Columbia Gorge Toyota) | Fuel Rebel 17″ -12 offset | Nitto Ridge Grappler 35×12.50R17 | 3.5″ lift kit | None after full trimming |\n| TRD ORP (6G4R.com test) | 17×8.5 +25 | Arroyo MT 35″ | Peak 2.25″ + 2″ rear | Rubbing, required bumper + fender trim |\n| ReadyLIFT 3″ SST Kit | 8″ wide +35 offset | 285/75R17 (33.8″) | 3″ front / 2″ rear | None, no trimming needed |\n\n## 37-Inch Tires: The Extreme Build\n\n37s on the 6th Gen have been done. Westcott Designs built the first verified 37″ 4Runner on their pre-collar lift kit with Method wheels, Toyo Open Country tires, and their full armor package. The key requirements:\n\n-   3″+ suspension lift with aftermarket upper control arms (UCAs)\n-   Aftermarket fender flares (1″ wider per side)\n-   Extensive bumper, rocker, and fender trimming\n-   Aftermarket front bumper strongly recommended\n-   Rear tire carrier (35″+ spare won't fit in the stock underbody location)\n-   Regearing recommended (4.30 or 4.56 ratios) for the [2.4L turbo](/guides/the-2-4l-turbocharged-i-force-4-cylinder-powering-the-new-toyota-tacoma-for-battle-born-adventures/)\n\nThis is a serious build requiring significant investment. Most 6th Gen owners targeting hardcore off-road capability settle on 35s as the practical limit for a trail-capable daily driver.\n\n## 5th Gen vs. 6th Gen: Why the Upgrade Matters\n\nIf you're coming from a [5th Gen 4Runner](/guides/why-the-toyota-4runner-is-the-ultimate-off-road-suv-capabilities-versatility-reliability-and-customization-options/) (2010–2024), the improvement in tire fitment is dramatic. The 6th Gen's move to the TNGA-F platform (shared with the Tundra) gave it substantially more wheel well clearance.\n\n|  | 5th Gen (2010–2024) | 6th Gen (2025+) |\n| --- | --- | --- |\n| **Biggest stock fit** | ~32″ (265/70R17) | ~33.7″ (285/70R18 on Pro/TH) |\n| **33s require** | Leveling kit + possible BMC | Stock on most trims, no mods |\n| **35s require** | 3″ lift + body mount chop + extensive fab | 2.5″ lift + bolt-on removals + bumper trim |\n| **Body mount chop?** | Yes, required for 35s | No, never needed |\n| **37s possible?** | Extreme builds only, major fab | Yes, proven with collar kit + trimming |\n| **Bolt pattern** | 6×139.7, M12 lugs | 6×139.7, M14 lugs |\n| **Center bore** | 106.1mm | 95.1mm (smaller) |\n\n**Critical note on wheel compatibility:** 5th Gen wheels will NOT bolt directly onto the 6th Gen. The M14 lug nuts and smaller center bore (95.1mm vs 106.1mm) require wheels to be drilled out. Most aftermarket manufacturers now offer 6th Gen-specific drilling.\n\n## What Affects Fitment: The Three Variables\n\n### 1\\. Tire Size (Diameter & Width)\n\nBigger diameter = more likely to hit at full suspension compression. Wider tires = more likely to rub at full steering lock. The combination of both is what creates fitment challenges. A tall, narrow tire (like 285/75R17 at 33.8″) can actually fit easier than a shorter but wider tire (like 315/70R17 at 34.4″).\n\n### 2\\. Wheel Offset\n\nThis is the distance from the wheel's centerline to the mounting surface. Lower offset pushes the wheel outward, increasing poke but decreasing clearance to fender liners, crash plates, and bumper edges. The 6th Gen community has settled on +25 to +35mm as the ideal range for larger tires.\n\n### 3\\. Suspension Height\n\nMore lift = more clearance at compression. But lift alone doesn't solve rubbing at full steering lock, that's an offset issue. A common mistake is throwing a 3″ lift on and assuming 35s will clear. You still need to address the contact points at the bumper, crash plates, and fender liners.\n\n## Practical Tips Before You Buy\n\n### 🛠 Things to Know Before Upsizing\n\n-   **Remove mud flaps first:** Free mod. Gives you immediate clearance for up to 33″ tires on most trims\n-   **Crash plates and splash guards are bolt-on:** All four are removable with basic tools and are reversible. Do this before any trimming\n-   **Repin fender liners before cutting:** Push the felt liner back and secure with existing hardware. This alone can save you from needing bumper cuts\n-   **Speedometer will read low:** Going from 32.6\" stock to 35\" tires means your speedo reads about 7.4% low (showing 60 when you’re actually doing about 64), and your odometer is off by the same amount. Most tuners or OBD tools can recalibrate ([Tire Rack maintains a tire spec database](https://www.tirerack.com/tires/TireSpecs.jsp) for verifying exact diameters)\n-   **Expect 1–3 MPG loss:** Larger, heavier tires increase rolling resistance. Budget for the fuel cost, especially with the 2.4L turbo\n-   **Spare tire considerations:** 33″ spares fit in the stock underbody carrier. 35″+ spares will NOT fit, you'll need a swing-out rear tire carrier or rooftop mount\n-   **Tire chains won't fit:** Per Toyota's owner's manual, tire chains cannot be mounted on 265/70R18 tires due to limited clearance. Larger tires make this worse. Plan for snow-rated tires if you drive mountain passes\n-   **E-rated vs SL tires:** SL (Standard Load) tires are lighter and ride smoother. E-rated (10-ply) add 10–15 lbs per corner and stiffen the ride. Unless you're running low PSI on rocks or carrying heavy loads, SL is fine for most builds\n\n## Frequently Asked Questions\n\n**Q: What is the biggest tire I can fit on a stock 2025 4Runner with no modifications?**\n\nOn the SR5 or TRD Off-Road with factory 17″ or 18″ wheels, 285/70R17 (32.7″) or 285/70R18 (33.7″) fit without rubbing. You may want to remove the mud flaps for extra clearance at full lock. On the TRD Pro and Trailhunter with their +20mm offset wheels, 285/70R18 (33.7″) fits completely stock with mud flaps still installed. Some TRD Pro owners have fit 295/70R18 (35″) on stock suspension with zero rubbing.\n\n**Q: Do I need a body mount chop for 35s on the 6th Gen 4Runner?**\n\nNo. Unlike the 5th Gen 4Runner, the 6th Gen does not require a body mount chop to fit 35-inch tires. The TNGA-F platform provides enough wheel well clearance that 35s can be achieved with a 2.5–3″ lift, crash plate/splash guard removal, fender liner repinning, and some bumper trimming. This is one of the biggest advantages of the new platform.\n\n**Q: Will 5th Gen 4Runner wheels fit the 6th Gen?**\n\nNot directly. The 6th Gen uses M14 lug nuts (vs M12 on the 5th Gen) and has a smaller center bore of 95.1mm (vs 106.1mm). You would need the wheels drilled to accommodate the new lug size. Most aftermarket wheel manufacturers now offer 6th Gen-specific options. Always verify specifications before purchasing.\n\n**Q: What wheel offset should I get for the 6th Gen 4Runner?**\n\nThe community consensus is +25 to +35mm for the best balance of stance and clearance. Stock SR5/Off-Road wheels are +55mm, which is conservative. The TRD Pro and Trailhunter run +20mm from the factory. Going below +25mm creates significant rubbing issues and is not recommended unless you're prepared for extensive trimming. For most builds targeting 33–35″ tires, +35mm offers the cleanest fitment with minimal modifications.\n\n**Q: Can I run 35-inch tires on the TRD Pro without a lift?**\n\nSome TRD Pro owners have confirmed that 295/70R18 (approximately 35″) tires fit on stock suspension with +22mm offset wheels and zero rubbing, even at full steering lock. However, this is at the limit. If you plan to off-road with full suspension articulation, a 2–2.5″ lift is strongly recommended to prevent rubbing under compression. For on-road use, stock height may be sufficient.\n\n**Q: What's the difference between the 6th Gen 4Runner and 4th Gen Tacoma for tire fitment?**\n\nThey share the same TNGA-F platform, so the front suspension geometry and wheel well dimensions are very similar. Tire fitment data from the 2024+ Tacoma is largely applicable to the 2025+ 4Runner, especially for the front. The 4Runner's rear is independent rather than a solid axle, so rear fitment differs slightly. Most owners find the 4Runner has equal or slightly better clearance than the equivalent Tacoma setup.\n\n**Q: Will a 35-inch spare tire fit under the 6th Gen 4Runner?**\n\nNo. A 35″ spare will not fit in the factory underbody spare tire carrier due to both width and ground clearance issues. If you're running 35s, plan on a swing-out rear tire carrier (brands like Westcott, CBI, and others make them for the 6th Gen) or a roof-mounted spare. Some owners carry a smaller spare as a get-home solution.\n\nBuilt for the Grind"
