Thanks Richard. I did go with the Shinkos, 275 in front and 300 in rear. Should have them mounted next week.

I recently picked up an Ace 90 and need to get new tires for it. Looking for a trials type tread. Any recommendations? Also, would a 3.00 x 17 fit on the rear and 2.75 X 17 work for the front?
Thanks for any thoughts/suggestions
Jim
