285/70R17 on a 3rd Gen Tacoma: The Complete 33" Tire Fitment Guide
Share
If there's one upgrade that defines the 3rd Gen Tacoma community, it's 33-inch tires. And the most popular way to get there is the 285/70R17 — the tire size that threads the needle between aggressive trail capability and daily-drivable manners.
With over 23,000 discussions and 305,000+ posts in the Wheels & Tires section of TacomaWorld alone, fitting bigger rubber on a Tacoma is the most-discussed modification in the entire community. But going from the factory 265/65R17 to a 285/70R17 isn't a bolt-on swap — there's lift height, wheel offset, trimming, UCAs, and speedometer correction to sort out.
This guide covers everything you need to know to run 33s on your 3rd Gen with confidence — whether you're hitting Nevada's high desert trails or just want your Tacoma to look the way Toyota should have built it.
Stock vs. 33s: What You're Working With
Let's start with the numbers. Here's how the stock tire compares to the 285/70R17:
| Spec | Stock 265/65R17 | 285/70R17 | Difference |
|---|---|---|---|
| Overall Diameter | 30.6" | 32.7" | +2.1" height |
| Width | 10.4" | 11.2" | +0.8" wider |
| Sidewall Height | 6.8" | 7.9" | +1.1" more sidewall |
| Speedometer Error | Baseline | ~7% under-read | 70 indicated = ~75 actual |
| Weight (approx.) | ~32 lbs | ~40–48 lbs | +8–16 lbs per corner |
That extra 2.1 inches in diameter and 0.8 inches in width is what creates the fitment challenge. The tire is taller, wider, and heavier than stock — and the 3rd Gen's fender wells weren't designed for it without modification.
Lift Requirements: How Much Do You Need?
This is the question that launches a thousand forum threads. The short answer: 2–3 inches of lift for 285/70R17 on a 3rd Gen Tacoma. The longer answer depends on your build goals:
| Lift Height | 33" Fitment? | What to Expect |
|---|---|---|
| Stock (0") | ❌ Not recommended | Significant rubbing at full lock and on bumps. Will chew through fender liners. |
| Leveling Kit (~1.5") | ⚠️ Tight | Barely clears at full lock. Requires aggressive trimming and mud flap removal. Not ideal. |
| 2" Lift | ✅ The sweet spot | Clears with minor trimming of the front fender liner. Most common setup in the community. |
| 2.5–3" Lift | ✅ Comfortable | Full clearance with minimal or no trimming. Aftermarket UCAs recommended at this height. |
| 3"+ Lift | ✅ No issues | Plenty of room. UCAs required. Could fit even larger tires at this height (35s with trimming). |
⚠️ Community Consensus
A 2–3" lift with 285/70R17 tires is the most popular combination on TacomaWorld by a wide margin. It's the setup that maximizes trail capability without destroying daily-driver comfort, fuel economy, or requiring major fabrication work.
Suspension Options: What to Buy
The suspension itself is the biggest investment after tires. The Tacoma community has spent 23,000+ discussions and 352,000+ posts debating the best options. Here are the community favorites by budget:
| Brand | Setup | Price Range | Best For |
|---|---|---|---|
| Bilstein 5100 | Adjustable height shocks (front) + OME or Bilstein rear | $400–$800 | Budget builds. Best bang-for-buck. Easy install. |
| Bilstein 6112 / 5160 | Front coilover + rear remote reservoir | $1,200–$1,800 | Mid-range. Excellent ride. Most popular "do it right" option. |
| Fox 2.5 Factory Series | Coilover front + remote reservoir rear (TRD Pro spec) | $1,800–$2,500 | Premium performance. Factory TRD Pro spec. Tunable. |
| Icon Vehicle Dynamics | Stage 2–8 kits with coilovers + rear shocks | $1,500–$3,500+ | Excellent ride quality. CDome technology. Strong community following. |
| King 2.5 OEM | Coilover + remote reservoir or piggyback | $2,500–$4,000+ | Top-tier performance. Exceptional off-road damping. Premium builds. |
Upper Control Arms: Do You Need Them?
At 2.5 inches of lift and above, your factory upper control arms (UCAs) are running the ball joint at or past its designed angle. This causes accelerated wear, reduces wheel travel, and makes it difficult to get a proper alignment. The community's rule of thumb:
- Under 2" lift: Stock UCAs are fine
- 2–2.5" lift: Aftermarket UCAs recommended but not critical
- 2.5"+ lift: Aftermarket UCAs are strongly recommended — ball joint angle and alignment issues become real
| Brand | Type | Price Range | Notes |
|---|---|---|---|
| Total Chaos | Uniball or ball joint | $700–$1,200 | Industry standard. Maximum durability and travel. |
| Camburg | Billet aluminum | $800–$1,400 | Precision engineering. Coilover and spindle systems available. |
| All Pro Off-Road | Steel, ball joint | $400–$700 | Value-oriented. Strong steel construction. Budget-friendly. |
Wheels: Bolt Pattern, Offset, and Top Picks
The 3rd Gen Tacoma runs a 6x139.7mm (6x5.5") bolt pattern with a 106.1mm center bore — the same pattern used on 1st, 2nd, and 4th Gen Tacomas, 4Runners, and early Tundras. That means a massive aftermarket selection.
For 285/70R17, the community-preferred wheel specs are:
- Size: 17x8.5 or 17x9
- Offset: -10mm to +4mm (most common: 0 to -10mm)
- Backspacing: ~4.5" (varies with offset)

| Method Race Wheels | MR305, MR312, MR701 | $250–$400 ea. | Community favorite. Beadlock models available. Clean designs. |
| Stealth Custom Series | Stealth 6, F5, SR8 | $225–$350 ea. | TacomaWorld community vendor. Dedicated forum (58 discussions, 9,261 posts). |
| Relations Race Wheels | RR6-H, RR7-S | $180–$280 ea. | Budget-friendly. Flow-formed for strength at lower weight. |
| TRD Pro OEM | Factory TRD Pro 16" or 17" | $300–$500 ea. | OEM quality. Available used from owners upgrading. |
Best 285/70R17 Tires for a Tacoma
The tire itself is where your money meets the dirt. Here are the community's top-rated 285/70R17 options by category:
| Tire | Category | Community Rating |
|---|---|---|
| Falken Wildpeak A/T3W | All-Terrain | ⭐ Community Favorite — best overall value and wet/snow performance |
| BF Goodrich KO2 | All-Terrain | The proven standard. Long-wearing and capable in everything. |
| Toyo Open Country A/T III | All-Terrain | Excellent on-road manners with solid off-road capability. |
| Nitto Ridge Grappler | Hybrid Terrain | Aggressive look, quiet on-road. Middle ground between AT and MT. |
| Falken Wildpeak M/T | Mud-Terrain | Top MT pick. Better road noise than competitors. |
| BF Goodrich KM3 | Mud-Terrain | Benchmark MT. Excellent rock biting edges. |
| Michelin Defender LTX | Highway / All-Season | Top highway choice. Exceptional longevity for daily drivers. |
Trimming and Clearance Mods
Even with a proper lift, most 33" builds need minor trimming for full-lock clearance. Here's what the community typically addresses:
- Front fender liner trim — the most common mod. A small section of the front inner fender liner gets trimmed to prevent rubbing during full steering lock. Simple heat gun + utility knife job.
- Mud flap removal or trimming — factory mud flaps are the first contact point on many builds. Most owners remove them entirely.
- Cab mount chop (CMC) — for builds that need maximum clearance (especially wider offsets), a cab mount chop allows the fender to sit slightly higher over the tire. This is common on builds with 0 or negative offset wheels.
- Pinch weld mod — bending the pinch weld along the front fender opening gives an extra fraction of clearance.
Speedometer Correction and Other Considerations
Running 285/70R17 tires creates approximately a 7% speedometer error. Your speedometer will read slower than you're actually going, and your odometer will log fewer miles than you drive. Options to correct this:
- OBD-II speedometer recalibrator — plug-and-play devices that adjust the signal. Yellow Speed, Hypertech, and others make Tacoma-specific units.
- Dealer reflash — some owners have had Toyota dealers update the tire size in the ECU. Results vary by dealer.
- Regearing — for builds also noticing sluggish acceleration (especially with the extra rotational weight), regearing the differentials from 3.73 to 4.30 or 4.56 restores power delivery. This also corrects the speedometer via mechanical ratio change.
Other things to expect with 33s:
- Fuel economy drop: Expect 1–3 mpg less than stock depending on tire weight and tread aggressiveness
- Braking distance: Slightly increased due to larger rotating mass
- Acceleration: Noticeably slower from a stop — the extra weight matters more than you'd think

SHOP TACOMA COLLECTION →Frequently Asked Questions
Can I fit 285/70R17 tires on a stock 3rd Gen Tacoma?
Not realistically. A 285/70R17 on stock height will rub significantly at the fender liner and during full steering lock. You need a minimum 2" lift, and most builds use 2–3" with minor fender liner trimming.
Do I need aftermarket UCAs for 33s?
At 2.5" of lift and above, yes — aftermarket UCAs are strongly recommended. They correct ball joint geometry, restore alignment, and increase wheel travel. Top options include Total Chaos, Camburg, and All Pro Off-Road.
What wheel offset do I need for 285/70R17?
Most builds use 17x8.5 or 17x9 wheels with an offset between -10mm and +4mm. Lower offsets give a wider stance but may require more trimming.
How much does the speedometer change with 33s?
About 7% under-read. At 70 mph indicated, you're actually going ~75 mph. Correct with an OBD-II recalibrator, dealer reflash, or differential regearing.
What are the best 285/70R17 tires for a Tacoma?
Community favorites include the Falken Wildpeak A/T3W (best value), BF Goodrich KO2 (proven standard), Toyo Open Country A/T III (best on-road), and for mud terrain, the Falken Wildpeak M/T or BF Goodrich KM3.
What bolt pattern does the 3rd Gen Tacoma use?
6x139.7mm (6x5.5") with a 106.1mm center bore. Same as 1st, 2nd, and 4th Gen Tacomas, 4Runners, and early Tundras — huge aftermarket wheel selection.
