'93 wheels

Will a 5x115 wheel fit on a 1993 cavalier? I know the size should be 5x100 but will it cause any problems? Also, are the stock size 14x6?

No that bolt pattern will not work. That means that the bolt holes will be spaced 115mm apart instead of 100mm.

And yes, the stock wheel size is 14x6.

no acually the stock should be 15x7. And 5x100 pattern. With a tire of 205/60r15Also if you go bigger then that you'll need lower profile tires. I have 17x7 MSR with 215/45r17

this should help for sizment
