Which tire size to go with?

Hello M3 community,



I have a question about which tire sizes to go with.



Some information:



Car: 2011 E92 M3 competition package

Suspension: stock ZCP

Wheel sizes: (Front) 19x9.5 et20

---------------(Rear) 19x11 et25



Tire choice: Michelin PSS or (maybe AD08, but heard it might have rub issues)



Some thorough research on the forum, it seems popular tire sizes would be:

(Front) ----------------- (Rear)

255/35/19 ------------ 275/35/19

255/35/19 ------------ 295/30/19

265/35/19 (too tall?)-- 295/30/19

265/30/19 ------------- 295/30/19

275/30/19 ------------- 295/30/19

----------------------- 305/30/19 (rub?)



The questions: ( I apologize for newbie questions, but I haven't found a definite answer yet)



1.) I'm having a dilemma for the front, should I go with 255/35/19, 265/30/19, or 275/30/19? Would any possibly cause rubbing?



2.) Would the 275/30/19 or 265/30/19 cause the front to have more of a gap between the fender and the wheel than compared to a 255/35/19? I know 35 is a taller profile than 30 but I'm not sure by how much.



3.) How about the rears? Would 295/30/19 cause more of a gap compared to a 275/35/19 or would it be barely noticeable?



4.) Also, why do some run a higher profile in the front and a lower profile in the rear, for example the 255/35/19 (F) and 295/30/19 (R)? Would this make the car uneven?



In my opinion, for the rear I like it wide :drool:, so I'm swaying towards 295/30/19 or if possible with no rubbing 305/30/19.
