| else 18x8 235/40R18 and 18x9.5 275/35R18 Honestly go with the wider rim and get the 285 on the back. You will need as much traction as you can. You can get the lower profile tires like a 285/30R18 and 245/38R18 and it may look better but you will have a stiffer sidewall which means less offline the traction and rougher ride.
