[RED RIDER]

I bought a set of OEM 343 M rims and am trying to decide what size tires to go with. I am thinking of going with a brand new set sized 245/35/20 Front and 285/30/20 in the rear. the front rim on these is 9". Some people say 245/35 will be too stretched on 9". I was hoping someone could let me know if this should be OK. The rims came with an almost new set of 265/35/20 and 295/30/20 Michelin PSS. Because my car is an XDrive, I could go with 255 in front but figured it would be best to get all new at the same time. Any suggestions would be appreciated. Thanks

245/285 is a perfect setup for xDrive model since they have identical rotation diameters. I don't see any problems so far and I believe 255/285 setup also fits the model. Generally you want the differences of rotation diameters to be less than 1%. Personally I like 255/285 setup.

I would stick with 245/285.

The easiest would be to only change the front tires to 255. 255/35 and 295/30 have matched diameters.

The front will look less stretched and it will be cheaper since you dont have to buy four new tires.

The issue with 295 rear is that it will be very aggressive on non M5 F10.

The 245/285 combo might be your best option after all.
