Can anyone tell me if they know anywhere to buy a 3.25x18 front trials tire?.  I am running a 1973 Yokohama that still looks pretty good, though I know that it probably isn't.  I figure that if I change the rim or tire size, that will screw up my speedo accuracy.

You can look on here for some options; www.yamaha-enduros.com/index.php/forum/g...6-master-tire-thread

It's also worth noting that most the stock speedometers are ~ 10% optimistic too.

Thanks, I'll check that out. I looked online and only found a Continental 3.25x18 trials tire at a online store in England, but when I clicked on it, I got an error page- probably an old ad. I have a 3.00x18 tire that looks a little small, but I could use it if I had to. I just sold my last street bike, and am getting the CT3 ready to run (it hasn't run for 36 years). I bought it in 1975, and am glad I kept it.
