Bests & Worsts Reviews from Amazon

While the following review was for the normal weight liners I haven't had a flat on the Ultra Lites either. Will update a mileage increases. So far, so good. Rode the Cross Florida (167 miles) twice with no flats, but honestly the tires looked very good afterwards so I'm not sure the liners got tested. Will update as mileage increases. Update: 1230 miles without a problem. I did get a pinch flat from hitting something on the road but the holes (yes 2!) were caused by the spoke holes through the rim tape. I had seen a fairly good cut in the tire earlier and when I checked the Mr. Tuffy liner I could see where something had poked it and deformed it but no hole in the liner or tube so that was clearly a flat I didn't get because of the liner. I'm removing the tires and tubes this week (6-22) for a thorough inspection and will update after. Update: 2200 miles, still no flats. Rear tire wore and while I replacing it, I found a piece of stainless wire stuck in the Mr. Tuffy liner (photo) but it didn't penetrate. Update over 6000 miles. Still no flats with several sets of tires. Last change had 3 visible holes through the tire including a large one caused by a piece of glass (2 photos). Nothing made it through the liner.
