OK so I bought some pirelli SL 26 tires and put them on my Helix and my CH250, both lasted under 1000 miles, ouch! That's with normal commuting and aggressive weekend riding, no skidding or anything crazy. I just wanna ride my scooter, not change tires or work on it! So what is everybody else running and how many miles are you getting? BTW I just replaced the pirelli with a IRC MB99, will see how long it lasts and post the results. Happy scootering!
