Wheels & Tires - Will a 5x120 rim fit on a trans am (instead of 5x120.7)?

Basically like the title says. Does anyone know? I know it wouldn't be ideal, but it's just for winter (yeah, I know, winter).

Probably shouldn't admit it but I ran a set of 5x120mm that came of a BMW on my 95 lt1 for years. You can see when you mount them that they don't fit IDEAL, put them on and don't run one lug nut down all the way, tighten the 5 lugs down evenly, and then recheck them often until they stabilize and they will be fine. If it was a track car I wouldn't do it, but it was a DD that my wife drove.

It'll generally work as long as the holes are big enough to give a little play and let you lock em down. For just winter I think it would be fine since you'll probably be driving slow and not loading the lugs/studs as much.

Just buy the correct ones and be done with it. Don't mess with the wrong wheels. Having play is not a great idea. I know its a 1 and a Million chance your going to f up but I wouldn't take the risk.

your talking about .027 of an inch. thats no much diff at all. My old car(97 GTP) was 5X115 bolt pattern and I had a set a 5x114.3 wheels that was on it for about 6 months and a set of mustang Cobra R's on it for months. Both git ideal with no problems

Theres a reason why tire shops like the one I was an employee at for years and others DON"T do it. Like i said 1 in a million chance but you never know. The crap shops down here will do it, 5 on 4.5 for a 5-115mm, whatever even if you have NEVER had problems that doesn't make it correct or proper.

I have seen lots of people run them with no problems. But at the same time I have seen some people run them and have problems.
A guy I worked with had a set on his Grand Am that were a 114.3 instead of the 5x115 that it required. Well one day out of nowhere one of his front wheels came off while he was luckily just turning a corner at around 5 MPH. Bring the car back to the shop and guess what, two of this other rims had all the lug nuts loose.
Sure it was a 1 time deal, but that one time could be you. Just get the right bolt pattern and not worry about it.
