I just purchased 20x9 Yellow Jacket Wheels with 275/40/20 Continental Extreme Contact Tires for my 2012 Dodge Challenger. Have about a 6mm spacer for fronts. I was assured they would fit without modification. When I took them to have them mounted there is very little clearance between the tire and the control arm (looks like less then about an inch and that was with it up on lift). Need some advise. Will these wheels and tires work without major damage/rubbing? Do I need to get 255 tires and try to sell the 275's? Or do I need to sell both the rims and tires and go back to 18" rims? Help!
