what rims did they crack?
i don't believe the size of a rim has anything to do with the durability of the rim.
i know a lot of the rims the "gangsters" put on their suvs are very low quality build but you can get a nice forged wheel like i'm looking at that are virtualy bullet proof. but like...
yes the center bore size is 108mm.
don't know what size you are going up to but anything bigger then a 22" with a 108 center bore is very hard to come by.
at least all the wheels i like are.
