When my 31s need replacing should a guy pony up like almost $10,000 for a set of 35s with the new light weight, Airframes made, wheels? What are the good, the bad and the uglies of 35s over 31s? Airframe says their wheel/tire combo weighs 54 lbs. Anyone know for SURE? I'll take one of my 31s off and weigh it. 10,000 clamolas is a lot of clamolas.
