I love Ride-On. I have had a screw in the tire and still rode it 25mi to the dealer without any loss of air pressure. They changed the tire under my Tire/Wheel warranty and never said squat about it. My only complaint is that is does seem to go in and out of balance at times. Doesn't stay balanced 100% of the time. I guess that is a small price to pay for peace of mind against most punctures.
