" Tire Dealer " !!!, I'll bet almost all TIRE DEALERS will tell you not to put a CAR tire on a MOTORCYCLE ..... if you go to Discount Tire, to buy a tire and tell them you are putting ANY of their tires on your Spyder :gaah:..... THEY WON'T SELL YOU A TIRE !!!!!!!!! ........... as I stated earlier " if it upsets you , don't use it " ...... Mike :thumbup: Now I'm curious about the Asymmetrical tire thing.... there are three types of tread - directional - symmetrical and asymmetrical ..... Why exactly are you concerned about using an asymmetrical tread on the REAR of a Spyder ?..... What do you think will occur differently from the other TWO ? .... I think a lot of folks here would like to know ... Mike :dontknow:
