[tinyblaster]

Hey i want to find the Diameter of a 98 Yamaha Blaster, and i could not find anything on the internet that would help me find it so i want to ask you now.
Does anyone now how to find the diameter of a Atvs back tire..I:I sorry wrong tittle

Is it not Pi x D ,,, 3.14 times the diameter?

Mind you I stand to be corrected as it is a long time ago since I went to school.

The diameter of the tyre will be written on the side wall eg. 22x11x8. So the diameter is 22" +/-. You can check your diameter with the tyre manufacturer since it will not be exactly what is written on the side wall. Yes the circumference is Pi (22/7) x diameter.

So are you asking Diameter (height) , or Circumfrence (distance around, aka "roll out") ? Dia is written on the sidewall of tire, 22-11-8 is 22"dia, 11 wide, 8" rim. Circumfrence would be 22x 3.1416=69.1152"
