15'' rim for spare tire

[gtx71]

Hello,

i am looking for the cheapest way to have a spare tire for my 1970 dodge challenger,
what 15'' rim with proper back spacing/ bolt circle can i buy from my local bone yard that will work.

Anything from a C body, truck or van will work as long as it's 4-1/2 bolt circle. These will typically be 15 X 6 or 6-1/2.

Just an FYI, E bodies never had 15" spares due to the small trunk space.

The tire size is more critical than the rim size. The rim size is just the size of the hole in your tire. One thing you can try is to get one of the current space saver spares as they are narrow and take up less space in the already small trunk. Like quapman said, just make sure that the bolt pattern is 5 on 4 1/2 "

Building on everyone's comments above you need to target in on a spare having an inflated tire diameter equal to your current non-spares, the 5 x 4 1/2 inch or 114.3mm bolt pattern, and 71.5mm center bore hole. I have used used mag wheels from swap meets, and new Nascar stye/wagon wheel steelies ($45 @summit)
