I'm in the same boat. I'm looking for some 30s or 31's for my jeep till i can put the 4 inch susp lift. I will keep my eye out for a spare tire rack for you. I took mine off a few days ago and i would toss you it but i dont want to give it away and end up needing it when i find my new tires ya know?
