Both those sizes especially the 305's will need wheel spacers or you'll get rubbing when turned lock to lock. Also if you do 33's without a lift I wouldn't disconnect your front sway bar or you are going to make tire contact with your fenders when flexing.Hello. I have a 2015 rubicon unlimited. I want to put some meaty tires on her. I'm looking at 305's can I put them on without having to do a lift? Without any rubbing or should've go with a 285?
