I am running 245/40/19 on the front and 285/35/19 on the rear. The rear is no problem. The front will have a slight rub when you hit full compression. I had one spot on the freeway during my comute that I would hit full compression if doing 80.

The problem caused in the front is do to the aggresive offset of the 166 rim (really made for a larger fender on the M5).

The rub was very slight on the top of the fender lip. I hated when it made the noise and I liked the look of these tire sizes, so I milled off 0.075 from the front rims to change my offset and corrected the rub issue. I do not believe there is a rim integrity problem as the rim is still 0.550 thick after the mod.

Yes but isn't the speedo reading affected because of the higher rubber walls?

How about the ride height? I think there's a 0.5 inch higher then OEM, correct me if I am wrong. Any rub issue when fully turn your wheel?

I wouldn't go with that tall a tire. This tire calculator recommends staying within 3% of stock tire height.

You can run 35/40 on non sport, but you still might run into rubbing issues. Most people change out the tires 245/35 and 275/30

Don't be cheap. It looks good with higher profile tires anyways.
