a fellow inmate was mounting a motoz 140/80-18 tonight on his 690 with the 2.5" wheel. i went over to see how it would fit the 990 4.25" wheel, and it is not even close. the tire's profile is nearly flat and would only be good in a straight line.
i am running a 140/80-18 karoo 3, and although not optimal, it fits the rim much better.
motoz, please come out with a 150/70-18.... pretty please?!?
