Recommended 5th Wheel Upgrade. When increasing the rolling diameter of your Jeep Wranglers tires it is recommended to upgrade your spare tire at the same time as the stock spare may be too small to be used. And besides a big meaty spare looks intimidating on the back of your Wrangler.

This Mammoth 4x4 wheel features classic Wrangler styling with an aggressive flare made to take on the outdoors. It's hub centric design provides the reliability you need on the highway and trail for a bold look no matter where your tire tracks end.Completed in a durable charcoal powder coat for a rugged off road appearance, this Mammoth 4x4 wheel is the perfect addition for the Jeeper looking for a custom styled wheel without a daunting price tag.  It comes complete with a matching Mammoth 4x4 center cap for complete aggressive styling whether you're on the trail or cruising the highway.

Your Wrangler will conquer climbs and pits and any obstacle with BF Goodrich's linear flex zone which allows this tire to conform to obstacles and grab the trail during aired-down crawling and driving.
