Possible rubbing with weight

amrh · 08-16-2018, 09:08 AM

Before I finalize sizes for wheels/tires, I need to confirm if rubbing will occur with stuff in the trunk and/or my kids in the back seat. I'm hoping someone has experience with this set up, and weight in the back.

Car is a daily driver, and we do Costco runs, at times. As well, travel with it (5 hour drive) to visit family. So, may have two small suitcases in the back. My kids are little... 8 and 5, so not much weight there...haha.

I'm most concerned about rubbing on the inside of the wheel well, not outside. I don't think there would be any rubbing on the outside of the wheel, even with weight in the trunk/back seat.

So, the set up is:
19 x 9.5 et19 - 265/35
19 x 11.5 et43 - 305/30
Tires will be PS4S

Any help is well appreciated! Thanks!

Front is OK except that I would suggest a 35 aspect ratio there.
Before I comment on the rear, you should know that I have no experience with a set-up like that. Having said that, arithmetic suggests that offsetting a wider rim further in then fitting a much wider tire is very likely to cause an issue. You should discuss this with a pro.
