325/60/20 with 20x9 +12 offset?
2007 f250 outlaw, K have the tires, have the ballistic jester 20x9 with the +12 offset on 325/60/20s mounted. I have a readylift sst kit that will add a tire of 37's but the 35's are rubbing. I have read others with the exact same kit I have running the same size tires on 8.5"rims with No rubbing. So I assume it's the offset. Readylift said 0 offset will work and the +12's wouldn't no matter if I got a bigger lift, but I've been told by others to do anything from 0 to 32 offset would work. Do I need to get wheel adapters/or spacers? Or just trim the plastic rubbery crap under the wheel well which I assume the shop means when they say it is rubbing....yeah sorry for all the questions, I'm frustrated as hell cause I love these rims and everyone keeps tellin me something different....plus I've had a bit to drink,, Help!!! Which offset will work and Why won't the +12 work!
