I've been using tire liners on my bikes for 25 years. In that time I've had two flats, one road the other mountain. Before that I was having flats all the time on my road bike. One of the best investments you can make as a cyclist. I prefer them greatly over tire sealer which I have also used. Install them and forget them, unlike sealer.
I've had my set of liners for three years now, and no flats. At least until I split a over-worn tire 15 miles from home. Despite the large hole in the middle of the tire, I replaced the tube and the Mr. Tuffy llner, and that got me home with just the liner between the road and the tube. Highly recommended if you hate flats.
I use these on my road bike and I haven't had a flat yet. I was having a lot of problems with those little wires from blown racial truck tires. I use gator tires with these inside, by the way they were easy to install. I check the tires to get the wires out as often as I can and this works well for me. Remember if you don't get the wires out occasionally they will work their way thru to the tube.
I have old Schwinn vintage bikes that have very limited tire selection. The tires do not have the new puncture resistance rubber so these liners are great so any glass will not give you a flat. I use these liners on all my bikes and ride about a 100 miles a week. Each time I have to dodge a broken glass field and other bikers just go pop and whistle as their tires go flat I have only had one flat with these liners from a large piece of glass after about 6000 miles. These liners will last for 3 or 4 tires so it is a small cost to prevent flats
I use these on all of my bikes....from grocery getter to mtb.....to ease my mind ,worrying about the dreaded flat.
Easy to fit and install....no having to cut to length cause they come in numerous sizes to choose from. Flexable yet strong along contact patch,no sharp edges to sand down or cut. Great product.
Put this product in my gravel bike tires to keep the tiny needle shards of disintegrated truck tire steel cords on the highway (normal in Arizona heat) and the goat head thorns that are off road. So far, I haven't had a puncture since putting them in. Worth the price and the frustration in dealing with both. Easy to install, and not a problem if and when the rare flat does a occur. A fair price for an excellent product.
I am a long distance cyclist. Installed Mr. Tuffy and have ridden three 500 milers and not one flat. This is a great value. You must be a bit careful on installing the liners to make sure they are seated properly but this is not a big deal. I have this product on all my bikes and no flats!!
I have worn tires down to the threads before with these in them and not had flats, nor did I even notice how thin the tires were since I usually start noticing the tires are getting worn when I start getting flats. Cuts out flats from punctures even when the tires are getting pretty worn and you usually start getting flats.
You still have to keep your tires pumped up regularly though since they do not stop pinch flats, as well as use the standard caution while installing tires to be sure you don't pinch the tube upon installing the tiretube (i.e. punctures are not the only source of flats, which some people may not know...)
If you ride in goathead country, and are tired of dealing with the mess of sealants like Slime, then, hello. I have been through countless goathead experiences. I have even taken tubes, cut off the valve stem, slit the tube on the innerside and used it as a shield between the tire carcass and the functioning tube filled with Slime, which makes your bike weigh a ton. No more folks! These babies are cleaner and lighter, and really work! Thank you Mr. Tuffy!
Upon installation, just place the still rolled-up Mr. Tuffy inside the tire carcass, and unroll it inside the tire, then insert the partially inflated tube to hold it in place.
Usually get six to eight flats a year. Decided to give the Tuffy's a try. So far no flats, have about 550 miles on them so far. I use them on my training bike where I am not concerned about weight. They are easy to install and have had no flats.
After several years riding with these liners, I can remember only 1 flat. The only time I take tires off anymore is to put on new ones. I easily go up to 4,000 miles without a flat. Also, if someone wasn't told they were in there and rode the bike they would never be able to tell the difference.
