Rear Tire Size

I am going to replace the rear tire for a Kenda 760 and the stocker is a 120/90-18 deathwing. Will a 120/100-18 fit ok?

Yes, the second number is just the width and you can fit a little wider tire on okay. I believe I have the same numbers, just with a k270.

Either way it will fit. This tire is a 110/100-18. I replaced it with a 150/90-18. Both fit great.

The 1st # is the tire width.

The 2nd # is the height (ratio).

The 120/100x18 is "taller" than a 120/90x18.

The same holds true for auto tire sizes...

A 70 or 80 series tire will be taller than a 50 or 60 series.

265/70x16 (taller) vs. 265/60x16 (shorter) profile

Correct.

I run a 140/80-18....140 wide, 112mm tall which is only a tiny bit taller than the stock 120/90 which is 108mm tall. I like the 140 in the mud and trails.

Either way it will fit. This tire is a 110/100-18. I replaced it with a 150/90-18. Both fit great.

That 150 will eat the hell out of your gearing tho compared to the 110/100. Did you change gearing to compensate?

Remember that these numbers are often more a guide than an actually mesurement.. 2 different makes/model of tyre with the same numbers will probably be different sizes and shapes.

Size and profile vary with the tyre application. Tyre manufactures make them for an intended bike or purpose. Deathwings are a road biasd tyre, the 760 aren't so the sizes have little relivance to each other..

Rick68fl, can I ask why you used such a large rear tyre???

Yeah, I had already changed to 14-47 sprockets. I had it out over the weekend with the new tires and it worked great!

I bought a Teraflex. Almost all of my riding is in deep sand and super soft stuff. I had been wanting to try out the teraflex for a while and finally went for it.

Makes sense.. When I saw your pic of the bike on sand that had crossed my mined.. We don't have alot of sand over here, especially near me..
