As the title says, I’m curious what everyone is doing for spare tires. I have a 1970. It’s not stock and so I’m not concerned about numbers correct. The reason I ask is, I want to run a space saver spare instead of a full size spare, but if I’m going to spend a bunch of money, I’d like to get one that is the same diameter as my rear wheels so I don’t burn up my posi unit if I have to use it. my rear tire is currently a bfg 245/60-r15 which is 26.57” tall and according to tire rack and it takes 781 revolutions to go one mile. also according to tire rack, I found a spare tire in the size of T135/90d17 to have the same dimensions. Unfortunately I can’t find a 17”x4” steel spare wheel. I guess I can buy a 17”x4.5” Aluminum drag racing wheel, but that’s getting expensive. It looks like gm never made a 17” spare tire in 5x4.75. I’ve seen them in 5x120, but I’ve had issues in the past with that size and don’t want problems on the side of the road! eventually I plan to change all of my wheels and the next set of wheels/tires will have a different diameter too so I’ll be doing this once again. I’m curious to hear how all of you are dealing with spare tires and non stock wheels. thx!
