Just about everyone agrees that the speed6 is too heavy and that the wheels/tires are too thin. So I am trying to decide between 225's and 235's on a 7.5 inch rim. Would you rather have the extra cm of the 235 even if it added 3lbs of unsprung weight per tire? Or would you give up the rubber on the ground for 12lbs of unsprung weight, tire weight all the way out at the edge where it is so hard to get moving? Sorry if ths should be in the wheels and tires thread but I'm not sure if weight and skinny tires is a problem of all 6s.
