Rim width

what is the widest rim we can put on our cars? ex.17x7, 17x8…

17x7, anything bigger then you will probably have to roll the fender lips.

17x8 is pushing it but it depends on the offset.

I have seen 18s but you can’t drop your car and I’m betting the guy had a really unpleasureable ride while using 18s. You would have to avoid even the very small pot hole like they were the plague.
