What I'm still getting my mind around is the classes... touring, grand touring, etc. I may end up with a pair of RT43s, they do have some similar points. They will be discontinued the instant I make a purchase lol. There are a couple older HPs with the lesser speed rating still lingering on my GT. I could deal with having those mixed in, but since they are on different wheels its gonna stay ugly until I get some swapping done at a tire shop. I'm needing to get some 15s for the 69 also. Killin me man.
