seen several sets for sale. wonder why? i wouldnt buy if needed adapters. rickson truck is about ready or has came out with 8 lug. i dont buy all the savings hype. mileage savings bcuz of lower revs more than lost to wind res. of lifted truck. also, big rigs run tons of highway miles so naturally get more miles out of'em vs around town tho will get better than reg tires. that being said, get the ricksons and enjoy 'em cuz they look awesome. wish my E series had what it takes to turn'em while towing. post pics when you get'em.
