I dont know if i am posting this in the right section. I am just trying to figure out if these new tires will fit my stock jeep wj without modification of if they require it, how much. I have a 99 Grand Cherokee with the stock 225/75/16s right now. I found a hell of a steal on some new tires with rims the only issue is they are 255/70/18. I just dont know if they will fit without rubbing and scrubbing or if I have to do any modification. I know the newer Wranglers come stock with the 255/70/18s. i am fairly new to the mechanical world of jeeps. I had an older xj before it died a horrible fiery death. Any help and advice is GREATLY appreciated.
