Looking to upgrade my wheels and tires. Decided on the "combo" 15x8 with 33x12.50s. That said, what backspacing do I need to get on the wheel in order to have no/little rubbing on suspension/steering components without pushing the tire out past my STOCK JK fenders? Gotta keep it PA legal and do not want to have to replace my fenders with fender flares. is 3.75 too little of a backspacing? if i go around 4.5 will there be a lot of rubbing? keep in mind its mainly a DD so rubbing while flexing isnt all that big of an issue.
