Match the Muscle of Your Rubicon 392
Designed exclusively for the powerhouse Jeep Wrangler Rubicon 392, this custom-fit spare tire cover combines rugged protection with aggressive styling. Featuring the distinctive "392 HEMI" graphic available in 5 striking colors, it is the perfect way to finish off your rig's look while defending your spare from the elements. Engineered for the grueling demands of the trail and highway, our Brawny Series is custom-tailored right here in Central Florida to provide a glove-like fit.
Why the Brawny Series Stands Out:
Heavy-Duty Endurance Vinyl: Crafted from marine-grade, UV-resistant denim-textured vinyl. It’s built to withstand road salt, intense sun, and trail debris without cracking or fading.
Vibrant Screen-Printed Design: The 392 HEMI graphic is direct-screen printed using a specialized solvent-based ink that bonds to the vinyl, ensuring it will last for years without peeling.
Fleece-Lined Interior: A soft poly-fleece lining protects your rim's finish and prevents tire off-gassing from distorting the vinyl over time.
Camera-Ready Design: Custom-tailored with a reinforced center port to maintain 100% full functionality of your JL's backup camera.
100% US-Made Quality: Hand-crafted using professional upholstery welt (piping) to reinforce seams for maximum durability.
Ordering & Fitment Guide
To ensure a perfect fit and avoid restocking fees, please verify your tire size before ordering. Check your tire sidewall (e.g., 315/70R17) or the driver-side door jamb placard.

Specialized Tire Packages
Jeep recently introduced expanded factory options for larger tires:

High Capacity / Recon Packages: For owners running the factory-optioned 37-inch tire upgrades or high-clearance fender packages, we recommend our specialized 37-inch w/Cam variant to ensure full sidewall coverage.
Jeep Trivia: The "392" Legend
Did you know? The "392" badge represents the massive 392 cubic inches of displacement in its 6.4-liter HEMI V8 engine. Pumping out an incredible 470 horsepower and 470 lb-ft of torque, the Rubicon 392 is the quickest, most powerful factory Wrangler ever created—rocketing from 0 to 60 mph in just 4.5 seconds!
