    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!

    Check Summit. My wheels are 17's with staggered sizes. I bought a steel 17x8 with one of my older smaller tires for the spare. Don't care for the donuts.

    I have the old school 15x7 wheels with 245-60-15 tires on all 4 corners of my car. I use a 5th 15x7 wheel for a spare with a F60-15 tire mounted on it.

    On my 71 my full size spare is 235X60X15 on the factory mag wheel. It doesn’t fit as good in the trunk as it should because of my rear speaker magnet sticks down too far for that factory fir.

    I don't carry a spare anymore.
    I used to carry a FR78-14 spare on a 14x7 rally wheel. (Equivalent to a P215/70R14 tire)
    It fit in the trunk with the sub, amp and rear speakers.
    (I chose speakers based on their height to allow it to fit.)

    Then I switched to a posi rear and 15" wheels (N90s) and didn't have room for a full size spare.
    I will get it flat-bedded with AAA if I ever run into a tire problem or any other serious drivetrain problem.

    I still have the jack and handle secured under the package tray but I'm not sure where the base is at the moment.
    It's not like I would ever trust the damn thing or a 40 year old spare tire. :confused:

    Well I bit the bullet and decided to buy the 135/90-r17 tire since per tire racks website is the same circumference as my normal 245/60-r15. This way I won’t burn out the posi if I have to use it in the rear. It also takes up less trunk space than the full size spare. I bought a jegs aluminum 17x4.5” ssr Star because I couldn’t find any steel wheels in the size I needed. It’s lighter than steel anyway. 9D66A7E3-0BC2-4CE8-AC4C-A9B199073770.jpeg D0C6F1C1-03F3-488A-87E6-A02443910A39.jpeg 41251D32-A9B9-48D3-AD88-A45656D2F2B1.jpeg D1A3574D-3910-4F81-BA74-7A459101C22D.jpeg 0E7BC8A3-6634-4185-BAD3-F7DA87C2F851.jpeg

    I went to a junkyard and pulled a mini-spare out of a 3rd Gen Camaro that was approx the right diameter
