Do rims from other cars fit the Corvette pattern,or are they specialized? I need a spare tire rim and would like to pick one up from the boneyard if possible.

I could be very wrong but I was always under the impression that a GM five bolt pattern fit any GM car. Just make sure you get something narrow enough to fit the car ( and fit in the spare carrier ).

I think the same. I have seen Oldsmobile rallye Rims on Pontiacs. I'm just not sure about the 'vettes.

i put one of the small spare on our 78 it went on ok

I thought about the space saver too. However, sometime this week, I may see if my 15" Oldsmobile Super Stock II rim fits. The 442 rims were 15 x 7 so that may be close enough if the bolt pattern is the same. If it does fitI may use it as the spare. Then again, I'll probably buy a used aluminum factory rim (to match the others on the car) and use that.

All 68-82 Corvettes have a 4.75" diameter, 5 lug bolt pattern. Contrary to popular belief, all Chevy 5 lug wheels are not the same bolt circle diameter. Some of the larger passenger cars of the 70's used a 5.00" diameter bolt circle, 5 lug pattern as well as all of the chevy 1/2 ton trucks. You can measure the bolt circle diameter on a wheel by measuring from the edge of one bolt hole across to the center of the farthest bolt hole from it. If you are looking for a spare, just make sure that the back spacing is enough to clear the brake calipers if you go with a narrower wheel. Should not be hard to find a wheel to fit.

The width of the wheel/tire shouldn't be a problem, but I'd be mindful of the diameter of the tire (depending on the series of the tire, height has a relationship to width) in addition to the offset of the wheel mentioned previously. If the diameter of the tire is smaller than the others on the car you will have some extra jacking to do if one of the rear corners goes flat on you so you won't run the risk of putting any extra strain on the differential.

First put the spare on a front corner, then put the tire just removed where the flat is. That way you'll have like tires on the rear corners. And then be easy on the brakes as you might get a pull with the dissimilar tires up front, especially if you have to stomp on them.

Thanks guys, that helps a lot.
