37 Inch Tires Kansas City
Kansas City's 37-Inch Tire Experts — Serious Off-Road Tires with Professional Fitment & Installation
37 Inch Tires in Kansas City
American Fusion Wheels is the Kansas City metro's specialist for 37-inch tire installation. Located in Shawnee, KS, we build trucks and Jeeps that run 37-inch tires safely, reliably, and with zero vibration. If you are stepping up to 37s, you are serious about off-road capability — and you need a shop that understands the engineering involved. Bigger tires mean bigger modifications, and we handle every aspect of a 37-inch tire build in-house.
Why 37-Inch Tires?
37-inch tires deliver serious off-road capability that 35s cannot match. You gain approximately one inch of additional ground clearance per side, significantly better obstacle clearance, deeper water fording, and a presence on the trail and street that turns heads. For dedicated off-road builds, overlanding rigs, and show trucks, 37s are the standard. They are not for every driver — the modifications required are substantial — but for those who need maximum capability, 37s are the answer.
Top 37-Inch Tire Models We Install
- Nitto Trail Grappler (37x12.50R17) — The most popular 37-inch mud-terrain at our shop. Deep tread voids, reinforced 3-ply sidewall, and surprisingly civilized road noise for a full mud tire.
- Mickey Thompson Baja Boss (37x12.50R17) — Aggressive asymmetric tread, PowerPly sidewall construction, and an unmistakable look. Excellent in rocks, mud, and sand.
- Toyo Open Country MT (37x13.50R17) — Open scallop design for self-cleaning mud performance. Strong value for a premium mud-terrain tire with a long tread life.
- BFGoodrich KM3 (37x12.50R17) — BFG's latest mud-terrain with Krawl-TEK compound for rock traction and linear flex zones in the sidewall for grip at low pressure.
- Interco TSL/Krawler (37x12.50R17) — Purpose-built for rock crawling and extreme trail use. Not a daily driver tire, but unmatched on technical terrain.
Lift Requirements for 37s
37-inch tires require significant suspension lift on every vehicle:
- Ford F-150, Silverado, Ram 1500: 6+ inch suspension lift minimum. Fender trimming or aftermarket fenders usually required for full articulation.
- Jeep Wrangler JL: 3.5 to 4.5-inch lift depending on trim. Rubicon fits 37s with 3.5 inches and fender trimming. Sport and Sahara need 4-4.5 inches plus high-line fenders.
- Ford Bronco: 3.5+ inches with fender modifications. The Bronco platform fits 37s well but requires more work than the Sasquatch 35s.
We install lift kits from BDS, Rough Country, Fabtech, McGaughy's, ReadyLift, and more. Every lift installation includes a full 4-wheel alignment.
Mandatory Regearing for 37s
Unlike 35-inch tires where regearing is sometimes optional, 37-inch tires require regearing on virtually every vehicle. The stock gear ratios (typically 3.21 to 3.73) cannot handle the larger rolling diameter — your engine will be lugging at highway speeds, your transmission will overheat under load, and your fuel economy will crater. We recommend 4.56 gears as a minimum and 4.88 for optimal daily driving and towing. Our Shawnee shop does ring and pinion swaps in-house — both front and rear axles — with proper setup and break-in.
Road Force Balancing for 37s
Road Force balancing is even more critical at 37 inches. These tires weigh 60 to 90+ pounds each — nearly double the weight of stock tires. Any imbalance or tire uniformity issue is amplified at highway speed. Our Hunter Road Force Elite applies a loaded roller to measure both weight balance and tire stiffness variation, catching problems that standard spin balancers miss entirely.
Full Build Components
Running 37s puts more stress on your entire drivetrain. We frequently upgrade brakes (larger rotors, heavy-duty pads), steering components (1-ton steering for Jeeps, heavy-duty tie rods for trucks), axle shafts, differential covers, and add steering stabilizers. We plan the complete build so every component is rated for the load that 37-inch tires place on the system.

Frequently Asked Questions
Common questions about 37 inch tires kansas city at American Fusion Wheels.
What lift do I need for 37-inch tires?
Most full-size trucks (F-150, Silverado, Ram) need a minimum 6-inch suspension lift for 37-inch tires with proper clearance at full steering lock and suspension articulation. Jeep Wrangler JL needs 3.5 to 4.5 inches of lift plus fender trimming or high-line fender flares — the Rubicon fits 37s more easily than Sport or Sahara trims. Ford Bronco needs about 3.5 inches with fender modifications. Toyota Tacoma and midsize trucks typically cannot run true 37s without extensive modifications including body mount chop. Call 913-291-2027 and we will assess your vehicle.
How much do 37-inch tires cost installed?
A set of four 37-inch tires mounted, Road Force balanced, and with TPMS reprogrammed typically costs $2,000 to $3,600 or more at our Shawnee shop, depending on brand and model. Nitto Trail Grapplers and BFGoodrich KM3s are at the higher end, while Toyo Open Country MTs offer strong value. This does not include regearing or lift kit costs, which are separate but usually necessary. We offer financing and wheel-tire packages. Call 913-291-2027 for a complete build quote.
Do I need to regear for 37-inch tires?
Yes, almost always. 37-inch tires dramatically change your final drive ratio, making your engine work much harder in every gear. We recommend 4.56 gears as a minimum and 4.88 for optimal daily driving and towing. Without regearing, you will experience sluggish acceleration, poor fuel economy, excessive transmission heat, and a transmission that hunts between gears on the highway. We do ring and pinion swaps in-house at our Shawnee KS shop — front and rear axles — so your vehicle drives the way it should with 37s.
Should I get 37-inch tires or 35-inch tires?
It depends on your goals and budget. 35-inch tires are the sweet spot for most drivers — trail capable, highway friendly, less lift required, and no mandatory regearing on most trucks. 37-inch tires are for serious off-road use where you need maximum ground clearance and obstacle negotiation. They require more lift, mandatory regearing, usually fender trimming, and upgraded drivetrain components. The total build cost for 37s is typically $3,000 to $6,000 more than a 35-inch setup. See our tire size comparison for a detailed breakdown.
Will 37-inch tires fit my Jeep Wrangler?
Yes, with the right modifications. A Wrangler JL Rubicon fits 37s with a 3.5-inch lift, proper wheel offset (typically -12 to -24mm on a 9-inch-wide wheel), and fender trimming or high-line fender flares. Sport and Sahara trims need 4 to 4.5 inches of lift plus more aggressive fender work. Regearing to 4.88 is strongly recommended — the stock 3.45 or 3.73 ratios are completely inadequate for 37s. We also recommend upgrading to 1-ton steering and heavier-duty ball joints. Our Shawnee shop has built dozens of 37-inch Wranglers for Kansas City drivers.
How do 37-inch tires affect braking?
37-inch tires significantly increase rotational mass — each tire weighs 60 to 90+ pounds compared to 30-40 pounds for stock tires. This extra weight takes longer to stop and puts more stress on your brake pads, rotors, and calipers. We recommend upgrading to larger rotors and heavy-duty brake pads when running 37s, especially for trucks used for towing or highway driving. At minimum, switch to a high-performance brake pad compound. Braking distance on 37s without upgrades can increase by 15-25 percent.
What kind of gas mileage will I get with 37-inch tires?
Expect a typical decrease of 3 to 5 MPG compared to stock tires. The heavier weight, larger rolling diameter, and aggressive tread patterns all contribute to increased fuel consumption. Proper regearing helps recover some efficiency by keeping your engine in the correct RPM range. Mud-terrain tires like the Trail Grappler or KM3 have a bigger impact on MPG than hybrid-terrain patterns. Most Kansas City drivers running 37s on a daily-driven truck see 12-16 MPG depending on the vehicle and driving style.
Is fender trimming required for 37-inch tires?
In most cases yes. Even with a proper lift, 37-inch tires at full steering lock or full suspension articulation will contact the fender, inner fender liner, or pinch seam on most vehicles. On Jeep Wranglers, high-line fender flares (like Metalcloak or DV8) replace the entire fender for maximum clearance. On trucks, the inner fender liner is typically trimmed and the pinch seam is flattened. We handle all fender modifications in-house at our Shawnee shop so your 37s fit without rubbing at any angle.

Open in Google Maps →"Had American Fusion Wheels install 37-inch Nitto Trail Grapplers on my Rubicon JL. They set me up with a 4-inch Metalcloak lift, 17-inch Method 305s, and trimmed the fenders for full articulation. We talked about regearing to 4.88 — they explained everything honestly and scheduled it for my next visit. Total for tires, wheels, lift, and fender work was about $2,800 for the first phase. Their Shawnee shop is about 20 minutes from my place in Olathe. Nobody else in Kansas City does 37-inch builds at this level."— Brandon L. 2020 Jeep Wrangler Rubicon JL
