So i have been searching around and am having a hard time understanding and finding the correct tire size. The stock size is 4-60-18. I am replacing the rear and want to go with the Cheng Shin C858. I am on bikebandit and these are the sizes for an 18 inch rim:

80/100-18
90/100-18
120/100-18

I would prefer not to get a taller tire due to the fact i am close to tippy-toe at 5'6. It seems like the 90 would be too skinny and the 120 too wide, i don't even know if thats the correct way to read them as far as width. But to me i wouldn't mind a little wider tire.

Also i was looking at the Kenda K270 which i have seen and heard alot about on this forum but their sizes are:

3.50-18
4.00-18
4.10-18
5.10-18
4.50-18- would this one be the closest to stock?

Any help/suggestions would be greatly appreciated.

Found two sites with 4.60-18 sized Chang woo tires =) I believe the stock tire is a 100/100-18. The 90/100-18 would be about 1/2" thinner and 1/4" shorter. The 120 seems a bit big for what you want. Do a search for "motorcycle tire chart" and you can find some usefull info.

 

80 is the height... 100 is the width.... and 18 is the rim size. your stock tire is a 100/100-18 right? so if you went with the 90/100-18 you should be fine.

 

The 120 width Dunlop 606 took some of the oomph out of my ride. It take more power to make it spin but, it's nice off road.

 

Thanks for the info, now i get it for the most part. I decided to go with the Kenda K760 Trak Master II. It seems like a more off road than on road tire. Like a 80%off / 20%on. The size ended up being 100/100-18 so it should be just like stock size.

I went with the 110/100 Trak Master and removed it after about 120 miles. It just wasn't the right pick for 90% street usage. I then put the Trak Master on my KDX and went riding this weekend at a state forest. Wow! that tire hooked up so well off road that I felt like I was riding a whole new bike. Fantastic tire for the off road.

It takes 80 to 100 miles to break the Trak Master in on the street so reserve judgement on it until then. After that period it's a little better on the street. Enjoy.
