I installed new slightly larger tires on my Jeep and the spare tire mounting lugs were too short for the wider tires. This 1" thick washer worked great to get the exact clearance I needed on a budget without creating too much space between the replacement part and the bolt like most adapters would. Replacement parts to the adapter using existing nuts It couldn't be simpler It didn't even need to make thicker tailgate bumpers, everything fitted together perfectly Great solution if your tires are a bit oversized and still fit the 3rd brake light but you don't have enough cleats.
