Hi to all the Mods and all the Seniors and Juniors too...

I am a newbie in this forum. This is my first post....

I have owned a CB twister two months ago. Everything is working very fine.
It has a average of 65-70 on Highway..I am very much impressed with it.

I did some tweaks to it..like lightings, paints, horn...

I want to change the rear tyre. I know that it will surely decrease the average but I want to change little big tyre. The size of rear tyre is 80/100 17". I asked to my friend who has R15.. he told me that I can fit 100/80 17" tyre.. I searched in the marked but I can find other sizes but I didnt find that..So, would u suggest which size is accurate for the rim..Actually I dont want to change the rim...

Thanks in advance...
