I have a ITB 1980 Mustang and I need some info on tires, i know there is a ton of things to know but I am just starting out and seat time is all I am worried about right now. but choosing a good type, brand and size that won't break the bank to start out with would be nice. I know a lot of things factor in weight, temp etc. but how long on the average do you get out of a set of tires?
