Well, I decided on the Nitto NT555 RIIs for the rear. 305/35 R20s. Tried to order them on Discount Tire but they refuse to mount them because they said they're too big for the stock 9.5" rim.
Any recommendations?
I went through the same thing with my hellcat. I paid the tech $50 and he did them after hours.
Don't go to a chain. Find a mom and pop garage. Be sure to tip them, they are a bitch to get on the rim.
