I have a 2009 Avenger SE and I want to go from my 215/65R16 with 16x6.5 to a 235/55R18 with Rage R20 wheels 18x8 with an offset of 40. I am concerned about tire rub whilst driving and also when turning. I don't know if they will fit without any type of spacer or mod. Should I buy them? Will they fit if its stock?
