If you get 20" with the profile 35 for fronts and 30 for rear, won't it make the wheel set diameter 1" bigger, thus the wheel gap is even smaller (and possibly rub)? Or do you mean with the 20", you will have 30 up front and 25 for rear? I would think for 20" with even thinner tires, it would be noticeable, no? Or do you guys just love the look of 20" too much that the slightly lower ride quality is negligible?

I have 19" and thinking about changing to a slightly higher profile tire (40 front 35 rear), which will make it 1" bigger, but I am afraid the gap is too small and it may rub... My car is lower 1.5" in front, 1.2" in back, which is similar to the H&R sport springs.

 

Um.. don't go 20's then. The ride will be harsher. 19's are okay, but if you want comfort stick with stockers. IMO, you need to lower your car on 19s or at least have the sport suspension because there's going to be a 2 inch gap. Plus in LA, 19 or 20, you are more likely to bend your rims because of the thin tire. You have to drive very carefully. So pick your poison:

Stockers = Safe, comfortable, but doesn't look as good.
19s = Semi-Safe, Semi Comfortable, looks good but you need to sport or lower it with springs which sacrifice ride.
20s = Scary in LA, drive like a grandma, looks great but you might need to roll your fenders or lower your car depending on the setup. Plus performance is sacrificed because the rim is heaver/larger diameter.


If I were you? Id stick with stock. If not, get M166 rims and use eibach springs.

 

yes 100% got 20" if you got the money

 

Depends how you fix it up and what color combo.. this is a friends M5 with maya 20's, not bad IMO
although he's M5 was lemoned..hmm what;s up with the lemon M5's? he told me he knows of around 9 of them..

 

i decided on 20's thanks guys for the input

 

good on you
post pic when you get them on.

 

You won't regret 20's trust me....it will give the car a total different look

 

and handing too.
