Mr. TuffyStandard Weight Tire Liner(Return to Product Page)

I was plagued w flats on my commuter bike so I pulled the trigger on the standard wt. Tuffy's. It was easy to put on and didn't really notice additional rolling resistance (my tires are already large 700 x 42). I only have few hundred miles on these but wo them I'd had a flat by now so I'm sure these are working like it suppose to. I like them so much that I bought the lighter versions for my road bike. So if you're getting more flats than you deserve slap these on enjoy the ride.

Yes, it adds weight and works, but some things get through. I do a fair amount of riding in the dark commuting to and from work in the northeast. Riding to work one early winter morning, I picked up a rather large piece of glass that gave me a flat. Don't worry, I was able to make it to work.
