As far as tire size I went with 245/35 21 front and 285/30 21 rear.

It provides more protection for the rims. Especially in the rear those 25's won't hold up for long against those rough patches of road.

275 in the front would be for the F90 M5. The front fenders on the M5 are "flared" and can accommodate 275's.
