I will for sure do a rebuild on the Knuckles... As for tire pressure it has alot less roll resistance |removethispart||removethispart|@ 32 it is a tad rough but I don't mind at least for now. As for wearing out the tires , I figure the Samurai has no weight to speak of anyway so the tires should last a loooong time. But you are correct and I do thank you for your input By the way...how much would you guess a '87 Samurai "Tin Top" would weigh?
