Why Upgrade to 37-Inch Tires on Your Ford F-250
The Ford F-250 is one of the most popular trucks on American roads — and for good reason. Adding 37-inch tires elevates your rig from a capable daily driver to a trail-ready machine that commands attention. At Godspeed Off-Road, we’ve built dozens of Ford F-250 rigs with 37-inch tires, and we know exactly what it takes to get the fitment dialed in.
At Godspeed Off-Road in Sarasota, Florida, we specialize in building Ford F-250 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 Ford F-250
The Ford F-250’s solid front axle gives you more straightforward lift options compared to IFS-equipped trucks. You have more room to work with and fewer geometry concerns, which means a cleaner installation and more predictable handling after the upgrade.
We typically recommend a 4 to 6-inch lift for running 37-inch tires on the Ford F-250. At 37 inches, you’re stepping into serious build territory. This upgrade demands quality components and professional installation to ensure your Ford F-250 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. The F-250’s heavy-duty components are built to handle serious loads, which means they take 37-inch tires in stride. A 4 to 6-inch lift with quality shocks gives you the clearance and the ride quality to match. The factory Dana 60 axles and large brakes are more than adequate at this tire size.
Regearing Your Ford F-250 for 37-Inch Tires
Running 37-inch tires without regearing is one of the most common mistakes we see at our shop. Your Ford F-250 likely came from the factory with 3.73 or 4.10 gears with a solid front axle (Dana 60 or equivalent). 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 Ford F-250
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 Ford F-250.
- 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 Ford F-250 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. 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. 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 Ford F-250?
No. Running 37-inch tires on a Ford F-250 requires a 4 to 6-inch lift at minimum, along with several supporting modifications including regearing, brake upgrades, and proper steering geometry correction. This is a comprehensive build that should be planned as a complete package, not pieced together over time.
Do I need to regear my Ford F-250 after installing 37-inch tires?
Yes — regearing is essential when running 37-inch tires. Your Ford F-250’s factory 3.73 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 Ford F-250?
We typically recommend 17×9-inch wheels with -24 to -44mm offset for 37-inch tires on the Ford F-250. 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 Ford F-250’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 Ford F-250?
Every build is different depending on tire brand, lift kit quality, and what additional modifications your specific Ford F-250 needs.
