I know this post is fairly old and you perhaps have already done something about wheels and tires. And I am new to the Macan world but consider myself fairly experienced in the subj of wheel/tire fitment. The rear fitment you list here -- 50mm offset with a wider rear wheel -- looks to me to be very aggressive; OE offset in the rear is only 19mm -- probably too aggressive and would rub in the rear with a 315. The inside of the tire would be about 41mm (31mm offset difference plus 10mm more tire on the inner edge) further in that with the OE stock 20s.Hi everyone, I did not see very many of you that put a 11 inch wide wheel on the rear of our cars, so I thought I would ask for some opinions. I'm looking to pick up a set of BBS RI-D in the following sizes. Do you guys think that I will be able to fit the rear wheel and have enough space on the inside? I have not looked behind the rear wheel to see how much room there is, and was hoping to get some input from you guys that have more experience. If I'm doing the math correctly, the rear wheel will need 1 inch more of clearance on the inside...
20 × 9.0J +25
20 × 11.0J +50
I would like to put a 315/35/20 on the rear, but I'm open to suggestions on tire sizes too.
Thanks in advance for the input.
Did you ever do anything on this project? How did it work out?
