Hello everybody.
I'm in Michigan and was wondering if I could put the wheels/tires off a 1990 Grand Prix,on my 1998 Grand Prix.I'd like to do this to keep the nice wheels on my 1998 from getting salt corrosion on them.
Is the bolt pattern the same on these wheels?Both cars have factory aluminum alloy wheels.

Thank you very much for any help.

I wanna say they are but hey take the 30 mins and see if one fits the other.

Thanks HercMan.
I have to dig the 1990 GP out of 2-3 feet plus of snow to get a wheel off it to try it out.Its 8 degrees outside,LOL.

I was hoping to get a definite answer here first before all that work.But what the heck,your right.The way to know for sure is to just take one off and try it.

Thanks man.

They should fit, according to this chart: http://www.custom-wheels-spinning-rims.com/Pontiac.htm See also: http://wheeltool.com/info/5bolt.html#5-115%20mm.

Thanks you guys.They fit perfectly,the center hole and bolt pattern were the same.Now I don't have to worry about my '98 wheels getting ate up by road salt.The '90 wheels still look good and will get me through this long Michigan winter.

I hate driving my '98 in this weather but I can't afford a winter beater right now.

My 1990 GP STE caught on fire under the hood 2 years ago and burned up alot of wires/cables etc.,but its still in near mint condition otherwise.I hated to junk it and I'm glad the wheels/tires interchanged.

Glad to hear that worked out, and welcome aboard!
