I have a 98 chevy 1500 moneys tight because I'm in highschool but I want to run 33x12.50r15 could you tell me how much I would have to cut off the bumper to run these. Also would a 15x8 rim be noticeably smaller than a 15x10 and is a 33x12.50r15 the same as a 285x75r15 if not what is I know its alot but thanks for the help. Also what kind of luck have you all had with 3m tape on cowl hoods?
