I have a 2000 WR 400 and i would like to put an IRC M5B on her, but i do not know what size of tire i can put on there, i know my stock tire size is 110/100/18, can anyone help me out? Any advice would help, Thanks

I had a 130/80 on my WR426 with no problems, and I've heard of people running 150/70s as well, the edge of the tyre just gets chewed be the chain a bit.

The IRC M5B 130/80 fits just fine on my 2.15 rim.

110/90 or 120/90 (Dunlop) is all I would use....
