Non Original Spare tire 1980 Pace Car
 

I have a 1980 Pace Car and I have an extra full size tire and rim

I put it in my trunk and it maxes out the trunk for basically anything else

Question is I don't want to buy the original spare and inflator to me that is show piece

I have seen what looks like a Dorman spare but I cant find what will fit an 80 TA

Something smaller than the full size and bigger than the inflator tire

Any help or experience would be appreciated

Been using a space saver spare that has correct bolt pattern. Dont know what it came from. Also carry a jack that comes in from the side of car. Wouldnt want to use the original that jacks on the bumpers. The space saver is a short tire and shouldnt be used on the rear with a posi axle. Would have to put a front tire on the rear and use the spare on the front. Sounds like a pain but didnt need to use it in 34 years. Its just there for peace of mind.

I would also second the suggestion of a space saver spare - sometimes referred to as "donut" spare - these are already air filled, and need no air cannister.
These were factory equipment in many early 1980's GM vehicles.

Or you could do like many people do these days;
Carry tire pump, and a can of flat repair - and have AAA.

Since I'm running the 17" Year One wheels, the next set of tires will be run-flats. Can't seem to find a donut spare at a decent price, and I've run into hub opening problems with some samples because a lot of cars shifted to hub-centric wheels in the 80s and those spares don't fit over the front spindle hub.

I've been using Bridgestone Drive Guard run-flats on my wife's BMW 428 for 80,000 miles with very satisfactory results. It is a definite stress reduction knowing she doesn't have to stop on the road with a flat but can drive to any Discount Tire for a replacement.
