I'm looking at a set of 20 inch player 5 spoke wheels with tires for 600 will a 5X114.3 fit on my car its a 98 oldsmobile 88 and I really want these wheels and if they won't fit is there a adapter

I believe you have 5x115. I seem to remember others using 114.5 It is only .7mm off so it wil be a tight fit. You could try it on for size before you pay. Just take a jack with you.

That'* the thing is this guy lives in superior wi and its like 2 hrs from me and I don't feel like driving that far just to not have them fit is there anyway of finding out if they will fit on my car I don't know bolt sizes on cars I only deal with 10 and 12 bolt petes and kenworths lol cuz I know 7 mm isn't that much I just wanted to make sure to check it out before I drive up there and get them its not a bad deal that'* why I really want the wheels

This here is the standard bolt pattern and off set of the FWD 87+ Bonneville. https://www.gmforum.com/t278853/ You will also need to know the offset of the wheels. To far in and it will rub when turning, to far out and you can hit the fender.

This is my personal feelings. I don't mess with wheels. they need to be the right ones. I think the bolt pattern will fit, it'* off by about 1/30th of a inch. But without knowing the offset, it'* hard to say how they will work on the car.

Some Pontiac and Chevy rims in the 60'* had a small difference, and you could wrench the them on, but in time they would pop the wheel studs. I myself bought a set of great looking snow tires on Pontiac rims, put them on a 66 Chevy wagon and popped two studs on one rear side and one on the other (Ya, I'm stubborn) before I took them off. I wouldnt do it.

no kidding... especially since the quality of manufacturers today vs the 60s when things were built to last... youd prolly break 3 studs just touching them to the rim hehe j/k

honestly i dont think it would work at all... its not much difference but i think its enough to not work... and unless they are backspaced REALLY FAR i wouldnt even consider an adapter... would push too far out and it would rub the fenderwell and bye bye tires, hello scratched rims

but you can always try it, in the words of Toddster, nobody said were perfect lol
