Curb rash is not just for wheels! Tires get curb rash too! Thts what I’m talking about! Holy shit get it through your thick skull! I get that a smaller diameter wheel= thicker sidewall= less chance of WHEEL getting curbed!Diameter has everything to do with curb rash. Maybe brush up on first-grade Math?
Larger diameter wheel = less rubber sidewall, which means your rim is closer to the ground, thereby increasing chances of making side contact with a curb.
17" rims on the other hand will have significantly thicker sidewall tires, which alleviate any side contact with curbs.
But you put a wider tire on there or a more negative offset wheel, your choice, the whole entire combo is going to stick out farther and you have more of a chance of curbing it. Even with my tires that stick out almost 1.5” past the fenders I have never curbed them when backing or parallel parking and using solely the reverse camera in the dash. Keep the curbs outside of the “colored lines” and you’ll never have to look in your mirrors for help.
