Hey what do i have to get (wheels) to get a decent 10 inch tire under my regal in the rear? backspacing offset? i have no idea. rim width? and what should i get for the front? i'm looking to put biggest streetable tires on this thing. and whatever i need in the front to be safe. HELP! time to spend some cash on wheels and tires!
..you can go to a 255 on typical GN rims big problems, but to go larger you really need to buy a new set of wheels. 275/60/15's are a pretty popular choice for the 455 Regal. Streetable I'd stay 195/60/15's up front at the smallest, but that's if you plan to drive around town. Lot of guys running smaller. I use a 205/50/15 all around for cornering.
