Hey all can a spare tire be purchased for my spare tire rim? thanks

Probably! I would start with your local tire discount store. They will probably have to special order it.

Why dont people goto junk yards anymore???

Yeah, the Junk.....ahem.....the Automotive Recycling Center would be your best bet. Ya know, I can't remember the last time I used my spare(but I do keep it inflated to 60 PSI just in case). Is the spare tire well deep enough to hold a full size tire/spare without a noticeable bulge in the trunk??? I don't think it can(especially the latest gen bonneville with the 17" wheels). Just wondering.

Junkyards? Crap I can never find Bonnies in junkyards...thats a good thing.

just toss a full size spare in the truck....thats always a good look.and just pile your various cargo items around it.

i tried using a sprae rim and tire off of a bonneville, and it wont work, I even deflated the tire to try and make it fit.

theres a junk yard in Mn in royalton and it has like 15-20 bonnies...just to let hte MN people know

Yeah I have no problem finding bonne'* around here. If you cant find a bonne try a Park Avenue or a Delta

LeSabre too. What about the W-Body'*(GP'*, Regals, Impala) wouldn't their spare tires work on the H-Body?
On my '91 Olds the Spare size is T125/70D/15. I'm guessing that they use a larger 16" rim for the newer H-body'*.

The Service Manuals state that you should NEVER try to mount a standard tire on a compact spare rim. The compact spare uses a narrow 4 inch wide rim.

I seriously doubt it. Although the regular tires will fit in the well, the trunk floor will bulge some. But if you don't mind the slight imperfection in the trunk, a regular size spare on a steel rim might be the answer.
