Lifting your Toyota 4Runner by 2–3 inches opens up a world of off-road capability, aggressive styling, and increased ground clearance. But with that lift comes a critical decision: choosing the right tire fitment. Get it right, and you’ll enjoy a balanced ride, optimal traction, and trouble-free clearance. Get it wrong, and you’ll face rubbing, poor handling, premature wear, and even driveline strain. This guide dives into the specifics of tire selection for a 2–3 inch lifted 4Runner — covering sizing theory, real-world fitments, potential modifications, and the trade-offs every owner should understand.

Understanding Your Lift: Suspension vs. Body Lifts

Before selecting tires, it’s important to know what kind of lift you have or plan to install. A suspension lift (springs, struts, spacers) raises the chassis by increasing the distance between the axle and the frame. This provides genuine ground clearance and allows for larger tires under the fenders, but it also alters suspension geometry and can affect driveline angles. A body lift (pucks between the frame and body) raises only the body, leaving the drivetrain and suspension at stock height. Body lifts provide extra clearance for tire tucking but don’t improve breakover angles or axle ground clearance. Most 4Runner owners combine a 2–3 inch suspension lift with a small body lift to fit oversized tires without aggressive trimming. For this article, we assume a suspension lift of 2–3 inches, which is the most common and practical modification for fifth-generation (2010–present) and fourth-generation (2003–2009) 4Runners.

Tire Size Basics: Decoding the Numbers

Every tire size follows the same metric standard, e.g., 285/70R17. The first number (285) is the section width in millimeters from sidewall to sidewall. The second number (70) is the aspect ratio — the sidewall height as a percentage of the width. So a 285/70 has a sidewall height of 70% of 285 mm (about 200 mm). The “R” indicates radial construction, and the final number is the wheel diameter in inches. To calculate overall diameter: (width × aspect ratio × 2) / 25.4 + wheel diameter. For 285/70R17: (285 × 0.70 × 2) / 25.4 + 17 ≈ 32.7 inches. This metric matters because a lift allows you to clear larger diameters, but the width and offset also determine whether you’ll rub against the upper control arm, fender liner, or sway bar.

2-Inch Lift Recommendations

With a modest 2-inch suspension lift, you can safely fit tires in the 32-inch to 33-inch diameter range with minimal rubbing, provided you choose the right width and offset. Popular options include:

  • 265/70R17 (31.6″) — essentially a stock replacement, leaves plenty of room, no rubbing, retains near-stock gearing feel.
  • 275/70R17 (32.2″) — a slight increase in width and height, requires careful wheel offset (typically +15 to +35 mm) and may need minor fender liner trimming.
  • 285/70R17 (32.7″) — the most common “plus-size” fitment for a 2-inch lift. Expect light rubbing at full turn or under articulation. A 0–25 mm offset and aftermarket upper control arms (UCAs) are often needed to center the tire in the wheel well and prevent rubbing on the frame rail.

3-Inch Lift Recommendations

A 3-inch lift provides the clearance to run 33-inch true tires comfortably, and even 34-inch tires with some trimming. The sweet spot for most daily drivers who off-road occasionally is a 285/75R17 (33.8″) or a LT285/70R17 (32.7″ but with a heavier load range). More aggressive owners go with 295/70R17 (33.3″) or 305/70R17 (33.8″) — but these require significant modifications.

  • 285/70R17 — still a great 33″ option, fits with a 3-inch lift and proper offset without major trimming. Very common and easy to find.
  • 285/75R17 (33.8″) — provides extra sidewall height for airing down; may require aftermarket UCAs, fender liner trimming, and sometimes a Body Mount Chop (BMC) to clear the firewall rub zone.
  • 295/70R17 (33.3″) — wider than the 285, better flotation in sand or snow. Requires aggressive trimming and possibly a BMC. Expect to run a 0–12 mm offset wheel.
  • 315/70R17 (34.4″) — this is the “true 35″ (actually ~34.4″). Only fits with a 3-inch lift after extensive trimming, BMC, aftermarket UCAs, pinch-weld trimming, and often a regear. Not recommended for daily drivers unless you are building a dedicated trail rig.

Wheel Offset, Backspacing, and Scrubbing

Even with the perfect tire diameter, the wrong wheel offset will cause tire rubbing against the frame, sway bar, or fender. Offset is the distance from the wheel’s mounting surface to its centerline. A positive offset pushes the tire inward toward the frame; a negative offset pushes it outward, increasing stability but also placing more load on suspension components. For a 2–3 inch lifted 4Runner:

  • Stock wheels typically have a +15 to +30 mm offset. They work for 265/70R17 and 275/70R17 with a 2-inch lift but will cause rubbing with 285s.
  • Aftermarket wheels with a 0 to +15 mm offset, 17×8.5 or 17×9 inches, are the sweet spot for 285/70R17 and 285/75R17. They push the tire outward enough to clear the upper control arm and frame, but not so far that they protrude beyond the fenders, risking debris spray.
  • Backspacing, the distance from the mounting surface to the inner rim edge, should be 4.5–4.75 inches for most 33-inch fitments. Less backspacing (more negative offset) can cause the tire to hit the fender at full lock.

Before buying wheels, measure your current clearance at full steering lock and at compression. Many owners use wheel spacers to achieve a better stance, but these add stress to wheel bearings and should be used sparingly. A dedicated aftermarket wheel with the correct offset is always safer.

Trimming and Body Mount Chop (BMC)

For larger tires (over 33″ or wider than 12.5″), some trimming is inevitable. Common modifications include:

  • Fender liner trimming — cutting or heat-gunning the plastic inner fenders back to prevent rubbing at full lock.
  • Pinch weld flattening — hammering or cutting the metal pinch weld behind the front tires to gain clearance.
  • Body Mount Chop (BMC) — cutting a portion of the body mount where the tire rubs at full turn, then welding a plate over it. This allows fitment of 295s and 315s without constant rubbing. It is a permanent modification that requires a skilled fabricator.

If you plan to run 285/75R17 or larger, budget for a BMC and aftermarket UCAs. Many 4Runner owners skip the BMC and live with minor rubbing under compression, but for serious off-roading, it is worth the investment.

Gearing, Speedometer, and Performance Considerations

Larger tires increase overall gearing, meaning the engine must work harder to turn the larger circumference. A stock 4Runner with 4.10 axle gears and 31.6″ tires will feel sluggish with 33″ tires, especially on hills and during highway passing. Regearing to 4.56 or 4.88 gears restores performance and keeps the engine in its power band. While not strictly necessary for 33″ tires, regearing improves acceleration, towing capacity, and transmission life. It also helps recover lost fuel economy — larger tires can reduce MPG by 1–3 on the highway.

Speedometer accuracy is another important factor. A 33-inch tire has approximately 4–5% larger circumference than stock. At 70 mph indicated, you will actually be traveling 73–74 mph. Use a GPS speedometer app to verify, or recalibrate using a device like the Hypertech Speedometer Calibrator or Toyota-specific scan tools. Some aftermarket tuners also allow speedometer correction.

Load Ratings and Tire Construction

Not all 33″ tires are built the same. Passenger car (P-metric) tires offer a smooth ride and lower weight, but they lack the sidewall strength for heavy loads and rough trails. Light truck (LT-metric) tires have reinforced sidewalls (often with load range C, D, or E) and are better suited for the 4Runner’s weight (around 4,700 lbs) and off-road demands. For a daily driver that sees light trails, a P-metric tire like the 285/70R17 Falken Wildpeak AT3W is fine. For overlanding with gear, consider an LT-rated tire. However, LT tires are heavier, which further impacts acceleration and fuel economy.

Pay attention to the tire’s load index. A load index of around 113 (2,535 lbs per tire) is common for 33″ LT tires. The 4Runner’s gross axle weight ratings are around 3,000 lbs front and 3,800 lbs rear, so a single tire can support the entire axle. But when fully loaded, have enough margin.

Top Tire Choices for Lifted 4Runners

Based on 4Runner forum consensus and real-world testing, these tires excel in mixed-road performance with a 2–3 inch lift:

  • Falken Wildpeak AT3W (LT285/70R17) — excellent all-terrain traction, snow-rated, long tread life, and quiet on-road. A top choice for daily drivers.
  • BFGoodrich KO2 (LT285/70R17, LT285/75R17) — legendary toughness, great sidewall resistance, and good mud performance. Can be noisy as they wear. Requires specific offset.
  • Toyo Open Country A/T III — quiet, smooth, excellent wet grip, and lighter than KO2s. A great alternative for highway-heavy owners.
  • Nitto Ridge Grappler (LT285/70R17) — hybrid tread that does well on mud and snow, aggressive look, but shorter tread life than ATs.
  • Cooper Discoverer S/T Maxx — tough construction, 3-ply sidewalls, good for rock crawling, but heavy and noisy on pavement.

Step-by-Step Fitment Decision Guide

  1. Determine your lift height — Measure the actual lift after installation (front and rear) because spring sag over time can reduce clearance.
  2. Identify your primary use — Daily driving with occasional trails: 32–33″ AT tires. Frequent off-roading and rock-crawling: 33–34″ MT or hybrid tires.
  3. Choose a target tire diameter — Use the recommendations above as a starting point. Do not exceed 33.8″ on a 3-inch lift without BMC.
  4. Select wheel size and offset — For maximum clearance with 33s, use a 17×8.5 wheel with a 0 to +15 mm offset. Verify that the wheel does not require hub-centric rings or excessive spacers.
  5. Check clearance at full compression — With the vehicle on a jack, turn the steering full left and right, and simulate bump travel. Look for rubbing on the fender liner, sway bar, frame, or body mount.
  6. Perform test fit — Mount one front tire and one rear tire, then drive slowly over a ramp or parking lot speed bump while turning. Listen for rubbing. If you hear it, plan for trimming.
  7. Order accordingly — Once you confirm clearance, purchase a full set. Have them mounted and balanced professionally, and get an alignment immediately.
  8. Recalibrate speedometer — Use a GPS app or professional recalibrator to correct for the larger tire size.

Potential Problems and How to Avoid Them

Rubbing on a Stock Offset

The most common mistake is running 285/70R17 on stock wheels. The tire will rub the upper control arm at full lock. Install aftermarket UCAs (like Total Chaos, Camburg, or SPC) that are adjustable and provide more clearance. Alternatively, use wheel spacers (1.25″) with stock wheels, but ensure they are hub-centric and of high quality.

Braking Performance

Larger tires increase unsprung mass and rotational inertia. Your stock brakes may feel inadequate, especially when towing or descending steep grades. Consider upgrading to brake pads with higher heat tolerance (EBC Yellowstuff or Power Stop) or a big brake kit. This is not mandatory for 33-inch tires but improves safety.

Transmission and Engine Load

With 33″ tires and no regear, the 2010+ 4Runner’s 4.0L 1GR-FE engine and 5-speed automatic transmission will hunt for gears on hills. If you drive primarily in flat terrain, it is manageable. For mountainous regions or frequent towing, regearing to 4.56 is strongly recommended. You can read more about the math behind gearing changes at 4x4Parts’ gear ratio calculator (analogous for Toyotas) to see how tire size impacts effective gearing.

Wheel Weight and Balance

Large LT tires are heavy. A LT285/70R17 can weigh around 55–65 lbs each. Combined with a 17×8.5 wheel (30 lbs), you are adding unsprung weight. This affects ride quality and can cause vibrations if not balanced properly. Use a shop with a high-speed balancer and consider road-force balancing. Also check wheel torque after 50 miles; vibrations can loosen lugs.

Conclusion

Choosing the right tire fitment for your 2–3 inch lifted 4Runner is a balance of height, width, offset, trimming, and intended use. For most daily drivers, 285/70R17 with an aftermarket 0–15 mm offset wheel and minor fender liner trimming offers a safe, capable, and aggressive look. If you want the maximum tire possible without major surgery, the 285/75R17 with a BMC and aftermarket UCAs is the way to go. Avoid the temptation to cram 35-inch tires under a 3-inch lift without full supporting modifications — you will sacrifice drivability and safety. Measure twice, lift once, and consult reputable 4Runner forums like Toyota-4Runner.org for real-world fitment galleries. With careful planning, your lifted 4Runner will look and perform exactly as you envisioned.
