I would appreciate any help on Tire selection for my 19" PG2s. I'm planning on installing 8.5 in front and 10s in the back on my 540. I'm not sure which tire size to go with. I'm not planning on lowering my car and I'm not sure if there will be a fender gap if I go with the 235-35/275-30 profiles. Would appreciate any input. Thanks.
