Well a friend of mine is giving me his 5 lug Falcon tires for free
because he crashed his 4th gen. pontiac trans am

so will his wheels fit on my 1991 N/A coupe?

his giving me the stock rims of his pontiac with the tires

 

your getting them for free, mount them up and find out.

 

5x114.3 Go find out.

 

Our rims have a 5x4.5" bolt pattern, the Firebirds are 5x4.75".

So no, they will not fit.

 

When did they change? I thought rwd GM cars were always 5x4.5 (cept for the big cars which were 5x5). Hmmm, learn something new everyday.

Later,
Bill

 

It took you over an hour to bump your own thread. It would have taken less than 10mins to get the jack out, get your tools, remove the lug nuts, remove the wheel and tried the pontiac wheel on your car.

 

small small GM(cavilers, sunbirds) are 4.5, small GM (S10, Camaro, monte carlo) are 4.75, and BIG GM (trucks, big body cars like olds 98) 5.25

small ford (mustangs small cars) are 4.5, and big ford (trucks and what not) are 5...

Rx7's are 4.5 although late modle(late 90's) FWD Monte's are 4.5

I don't think he has the rims yet.

 

yeah i still don't have the rims yet
well once i do i'll check and find out if it worked or not

 

the best way to find out is if you install and see....dont force it on though...if it doesnt fit you can always sell em

 

Maybe have the wheels drilled out and inserts pressed in to get them to 114.3??
Show pics of the wheels.
If you know how to measure bolt pattern, u don't need to install it.

 

I wouldn't advise drilling out wheels like that, it's just asking for trouble.

 

They won't

 

well since some believe they won't fit
the tire size itself are
205/55R16
will this tire size fit on my stock rx7 rims

 

Well since you have a 91 NA coupe, the stock wheels are 15x6. Those are 16" tires. That is the stock TII and GTUs tire size and will fit on those wheels, which are 16x7.

So unless you've got other than stock wheels, then no those tires won't fit.
