As I have stated, My mr will be for trail riding. I am wanting to change the enduro tires to a more aggressive tire and would like to go up 2 or more sizes on the rear. currently the front is 3.00X21 and the rear is 3.50X18. Any suggestions? Sizes? Types?

Mine has the original tires on it and they are 300x21 and 400x18. I just bought an extra rear wheel and it has a 450 on it so they must fit. I also have an old Cycle magazine from April 1976 and they put a 350 on the front to help in desert racing

cool! So my rear has been changed to a smaller size... no wonder it doesn't look right. A couple of more, if you don't mind, are your tires enduro style or a knobby (dirt only) style? Have tire companies changed the sizing info for bike tires like they did car tires? I was on a site looking at tires and none of the numbers matched what I had. There were no 3.00X21 and such. Good lord am I showing my age or just my stupidity?

Mine are knobbies, the front one is called Motocross-7 and the rear is Motocross-6, and are original to the bike with only 1150 miles on them. Your right the sizes have been changed and as I understand some tire companies web sites have the sizing charts on them, but I have never looked myself.

Back in the day metzler was the tire of choice. I've checked out a couple of sites and see that they seem reasonable. I am going over to a bike shop in the next town on saturday to pick up my parts and thought I'd check out their selection. I've been out of bikes longer than I was into them and man, things have changed!!!
