Hey Guys
I can get a killer deal on some Barbus wheels with tires for the crossfire. They are 18 inch rims. The tires on them now are 235/40 ZR18's. Is there any issue in running these all around on all 4 wheels. They are off a Benz 190e

thanks

 

its a downgrade in rear traction but they should fit and ride well, do the tire height calculations on tirerack.com to verify same height

 

Does anyone think there would be a issue of a wider tire in the front ? (rubbing ?)
