37 Inch Tires Marietta GA

37 inch tires for serious lifted truck builds

Road Runner Wheels & Tires is the Marietta GA shop where 37" tire builds happen. If you've got a 6" lifted F-250 ready for 37x13.50R20 Mud Grapplers, a Ram TRX wanting 37x12.50R22 Ridge Grapplers, or a King-of-the-Hammers Jeep build needing 37x13.50R17 Trail Grappler M/Ts, we have the inventory and the install bay.

37" tires aren't a casual upgrade — they need proper lift kit + bumpstop work + fender trim. We'll check your build before mounting and tell you straight if something needs adjustment. Same-day mount + Hunter Road Force balance + TPMS programming on most fitments.

The 37" sizes we stock most

• 37x12.50R17 — Jeep Wrangler/Gladiator builds, Bronco off-road builds — Mud Grappler + Trail Grappler M/T
• 37x12.50R20 — the half-ton sweet spot — F-150 Raptor, Ram 1500 TRX, lifted Silverado 1500 — Ridge Grappler dominates here
• 37x12.50R22 — premium lifted truck + lifted dually builds — Trail Grappler M/T, Ridge Grappler
• 37x13.50R20 — wider profile for serious off-road traction — Mud Grappler, BFG KM3
• LT37x12.50R17, LT37x12.50R20 — LT-metric 37" with E or F load range for heavy-duty 3/4 + 1-ton trucks

What you need to run 37" tires

37" tires require more than just a lift kit. Most builds need: 6"+ lift kit (BDS, Rough Country, ReadyLIFT, Fox), bumpstop modifications, front fender liner trim, regeared differentials (4.10s minimum, 4.56s preferred), and often upgraded driveshafts on solid-axle trucks. We can spec out the full build for you.

37" tire install — what to expect

60-90 minutes for 4 tires once your truck is in the bay. Hunter Road Force balance is critical at 37" — small balance issues become highway shake. TPMS sensors reset, lugs torqued to spec, road-tested before keys back. For dually 6-wheel 37" sets, plan on 2 hours.

Pair 37s with the right wheel + offset

37" tires need wheels with serious backspacing and aggressive offset for clearance. We carry the full KG1 Forged truck line, American Force, Fuel Off-Road, Method Race Wheels, Hostile, and Black Rhino — all sized for 37" tire builds. Bolt patterns: 5x5, 5x5.5, 6x5.5, 6x135, 8x6.5, 8x180.

Already running 35s? Step up to 37s

If you're on 35" Mud or Ridge Grapplers and want to step up to 37s, expect: bigger lift, regear, more clearance work. We'll walk you through the cost + downtime. Most 35→37 builds take 2-3 shop days for the kit + tire install combined.

Or stick with 35s

If 37s feel like overkill, see our 35 inch tires Marietta GA page — same brands, smaller sizes, less lift work required.
