Why Upgrade to 37-Inch Tires on Your Toyota Tundra
Toyota built the Toyota Tundra on a foundation of legendary reliability and genuine off-road engineering. Upgrading to 37-inch tires takes that already impressive platform and elevates it into serious trail-ready territory. For Toyota Tundra owners in the Sarasota area, this is one of the most impactful modifications you can make — more ground clearance, better approach angles, and a stance that matches your rig’s capability.
At Godspeed Off-Road in Sarasota, Florida, we specialize in building Toyota Tundra rigs with 37-inch tires that perform on the trail and turn heads on the street. Every build starts with a conversation about how you use your rig — and ends with a vehicle that exceeds your expectations.
Lift Kit Requirements for 37-Inch Tires on the Toyota Tundra
Your Toyota Tundra uses independent front suspension (IFS), which requires more careful consideration when selecting a lift kit. Unlike solid-axle vehicles, IFS trucks need proper upper control arm (UCA) corrections to maintain safe ball joint angles and alignment geometry. Cutting corners here leads to premature wear, poor handling, and expensive repairs down the line. We use quality aftermarket UCAs on every IFS lift we install.
We typically recommend a 4 to 6-inch lift for running 37-inch tires on the Toyota Tundra. At 37 inches, you’re stepping into serious build territory. This upgrade demands quality components and professional installation to ensure your Toyota Tundra performs reliably both on the trail and during your daily commute. The investment pays dividends every time you tackle terrain that would stop a lesser rig. Running 37s on a Tundra is a statement build — and the full-size Toyota platform can handle it with proper support. A 4 to 6-inch lift with long-travel suspension components, heavy-duty UCAs, and CV-angle correction keeps the front end working properly. The Tundra’s wide stance helps with stability at this tire size.
Regearing Your Toyota Tundra for 37-Inch Tires
Running 37-inch tires without regearing is one of the most common mistakes we see at our shop. Your Toyota Tundra likely came from the factory with 3.91 or 4.10 gears. Those ratios were calibrated for the stock tire diameter — increase that diameter without compensating, and you lose acceleration, towing confidence, and fuel economy while putting unnecessary stress on your transmission.
For 37-inch tires, we recommend 5.13 gears. This ratio restores the mechanical advantage your drivetrain was designed around, keeping RPMs in the sweet spot for both highway cruising and low-speed crawling. Our regearing service includes new ring and pinion sets, fresh carrier bearings, and precision setup with gear marking compound — because a gear install done wrong costs more to fix than doing it right the first time.

Top 37-Inch Tire Brands We Recommend for the Toyota Tundra
Not all 37-inch tires are created equal. Based on thousands of miles of real-world feedback from our Sarasota builds, here are the brands we trust:
- BFGoodrich KO2 — The gold standard for all-terrain performance. Outstanding sidewall strength, excellent wet and dry traction, and a tread life that justifies the investment.
- Nitto Ridge Grappler — A hybrid all-terrain/mud-terrain that delivers aggressive looks with surprisingly quiet highway manners. One of our most-requested tires for the Toyota Tundra.
- Toyo Open Country A/T III — Exceptional all-weather capability with a 65,000-mile treadwear warranty. A smart choice for daily-driven rigs that still see trail time on weekends.
- Mickey Thompson Baja Boss A/T — Race-inspired tread design with serious off-road capability. If you want a tire that looks as tough as it performs, this is it.
- Falken Wildpeak A/T3W — Outstanding value without compromising performance. Heat-diffuser technology in the lower sidewall makes this tire remarkably durable in Florida’s heat.
Additional Modifications Worth Considering
Building your Toyota Tundra for 37-inch tires is a comprehensive project. Beyond the lift and regear, these modifications are essential for a reliable, well-balanced rig:
At this tire size, brake upgrades move from optional to strongly recommended — larger rotors and upgraded calipers ensure your stopping power keeps pace with the added rotating mass. Heavy-duty aftermarket upper control arms are mandatory to maintain safe suspension geometry. You’ll want 17×9 or 17×10 wheels with aggressive offset for proper clearance, extended brake lines, a heavy-duty steering stabilizer, and high-quality bump stops. Some fender trimming or aftermarket fenders may be necessary for full-turn clearance at full suspension compression. Skid plates, rock sliders, and a reinforced front bumper round out a build at this level.
Frequently Asked Questions
Can I fit 37-inch tires on a stock Toyota Tundra?
No. Running 37-inch tires on a Toyota Tundra requires a 4 to 6-inch lift at minimum, along with several supporting modifications including regearing, brake upgrades, and aftermarket upper control arms. This is a comprehensive build that should be planned as a complete package, not pieced together over time.
Do I need to regear my Toyota Tundra after installing 37-inch tires?
Yes — regearing is essential when running 37-inch tires. Your Toyota Tundra’s factory 3.91 or 4.10 gears were calibrated for stock tire diameter. Going to 37 inches without regearing to 5.13 causes sluggish acceleration, transmission hunting, increased drivetrain stress, and reduced fuel economy. The regear investment protects your transmission and makes the truck actually enjoyable to drive. Read our complete regearing guide.
What wheel size works best with 37-inch tires on a Toyota Tundra?
We typically recommend 17×9-inch wheels with -24 to -44mm offset for 37-inch tires on the Toyota Tundra. This combination provides proper backspacing for brake caliper clearance while giving you the right stance and preventing tire contact with suspension components. Beadlock-capable wheels are worth considering if you plan to air down significantly on the trail.
How do 37-inch tires affect my Toyota Tundra’s fuel economy?
Expect a decrease of approximately 2 to 4 MPG compared to stock. The larger, heavier tires create more rolling resistance, and the increased rotational mass requires more energy to accelerate. Regearing to 5.13 helps minimize this impact by keeping your engine in its optimal RPM range. Proper tire inflation and a quality alignment also help maintain the best possible fuel economy with your new setup.
What is the total investment for a 37-inch tire and lift package on my Toyota Tundra?
Every build is different depending on tire brand, lift kit quality, and what additional modifications your specific Toyota Tundra needs. Rather than quoting a generic number, we prefer to discuss your goals and spec the right package for your rig. Call us at (941) 706-0071 for a personalized consultation — we’ll walk through the options and put together a build plan that matches your budget and your vision.
