Rear tire 140/80-18

I'm running Dunlop 606's. 120/90-18 but i'm thinking about a Motoz Tractionator Desert H/T Hard Terrain Rear Tire in 140/80-18 or 130/90-18. Will they fit? Anyone use them?

Get the 110/100, theres a youtube vid or two showing it on other 250's. The 130 would fit but the bike wont like it, its huge and heavy which kills power and cornering.

The motoz desert tires last forever but don't bite as good as a 606 offroad but are better than stock or a shinko244, which is exactly what lots of guys need.

I haven't tried one but am looking into getting one as I'm doing more road stuff on my wrr now than I was.

Thanks. I found the video.
