I am having a Grand Prix worked on in a bike shop and I want to buy new wheels and tires for it and have them put them on. I ride about 80% on regular pavement and 20% dirt/gravel. I am looking for the best I can buy for $100 (for both wheels and tires). The most important thing to me is the strength of the wheel and the ability for the brakes to work well (not too much to ask, right?). Right now I have these semi-hybrid tires which are thin but have knobbies on them...I wouldn't mind having these kind again..The old ones are rotted out and everyone tells me any day know they're gonna pop!
I don't know tire/wheel sizes and have no idea what's on my bike now...What's a standard size?
