Step up your puncture protection with Mr. Tuffy Tire Liners.

These re-usable polyurethane strips form a protective barrier along the inside of your tire, increasing protection against inner tube punctures caused by sharp objects like thorns and broken glass.

Mr. Tuffy liners are lighter than self-sealing and thorn resistant inner tubes, effective against a wider variety of road hazards, and they're easy to install -- no gooey mess. Sold in pairs (enough for one bicycle). Made in the U.S.A.

Choose the color which corresponds to your tire size:

  • Orange: 700c x 20-25mm / 27 x 1" (57g)
  • Red: 700c x 28-32mm / 27 x 1 1/8" / 27 x 1 1/4" (52g)
  • Gold: 700c x 32-41mm / 29 x 1.5-2.0" (69g)

No more flats! And no need to be technical to use.
by Clean Nails in Tucson
Casual Cyclist
Tucson, AZ

I fixed a lot of bikes in my 20s, but now I'm 40, and I like having clean nails and dislike bending over for too long. Anyway, this worked to fix my husband's issue with flats and didn't require any goop or valve-stem removal or anything like that. We live in AZ and his first day commuting 5 blocks to work he got 4 holes from dreaded goat heads. And since we added these, he's had no flats in 2 months of commuting (though the goat heads are still there, trust me). So, these work great. Here's how I dealt with adding them to the tire:

1. Put one beaded edge of the tire in the rim.

2. Added the liner into the tire. I tried to hold it there with Scotch tape, which didn't work well because the liners are so slick. Duct tape would have worked better, so try that.

3. Fit the tube into the tire.

4. Squash the other beaded edge of the tire into the rim.

Highly recommend!

Flat proof....no Flat resistant...YES
by crunch

portland, or

i have been using these liners for several years now and very happy with the results. Provided the tires are inflated properly the flats i do get are ones I deserve for example pulling out a 3 inch staple from my tire or other. these guys are really good and happy with the result. flat proof....no? Flat resistant.... yes.

I have read that some have challenges installing them, but its quite simple if you lay the rim flat after the tire is partially mounted and insert the liner and then tube. no big deal.

Use Mr. Tuffy in my mountain bikes for trail riding to prevent blackberry thorns from puncturing. I also convert on of my mountain bikes for winter when I install road tires but keep the Mr. Tuffy in to prevent punctures from road debris.

Used This Tire Liner Product on Multiple Bikes Over 25 years
by Gio

I've used Mr. Tuffy tire liner products on both a road bike and mountain bike for over 25 years and have generally been satisfied with the product's quality and usefulness. However, it's still possible for a Mr. Tuffy tire liner to inadvertently puncture a tube.

This manufacturer's tire liner will generally block small, sharp items like a piece of broken glass from puncturing a tube, but the liner won't stop a larger, sharp piece of broken glass or any type of nail, for example. Also, given that the liner is supposed to be seated in the middle of the tire, don't expect protection for the tire's sidewall.

The manufacturer's claim that their tire liner will Absolutely, Positively not cause tube damage isn't true.

When installed, the tire liner must be seated directly over the tube and generally centered in place all the way around the inside of the tire wall. This process remains difficult to achieve perfectly so that the tire liner is seated correctly. Frankly, it's nearly impossible to get both the tube and tire liner properly seated together, especially when re-mounting a Michelin Pro 4 Endurance tire model. There's a slick, slippery finish to the tire liner that makes it difficult to keep in place while attempting to position a tube. So, the tire liner moves around a bit, can end up not being centered over the tube, and is instead pushed off to either side of the tire, and therefore may end up with a small bend or crimp in the edge of the tire liner.

If there's a small bend or crimp in the edge of the tire liner, the end of the bend or crimp forms a small, V-like point that rubs a hole in the tube and causes a flat. Mr. Tuffy tire liners previously had hard edges that historically caused flats. A significant improvement was the softening of the tire liner's edges so that flats wouldn't occur. However, a bend or crimp in a tire liner not perfectly seated can cause a punctured tube.

I bought a set of Mr. Tuffy tire liners in May, installed them in June, and new tubes in both my front and rear tires were punctured by a small, V-like point at the end of the bend or crimp in the tire liner. I've never had this happen before. I'm not happy that it cost me approximately $16.00 for two new tubes.

Nevertheless, I ride through a lot road debris on Pacific Coast Highway in southern California, and still believe this is a worthwhile product when its installation if achieved perfectly such that the tire liner is centered and seated correctly all the way around the tire.

I use the Mr. Tuffy tire liners inside a Michelin Pro 4 Endurance tire model on a 700x23 wheel.

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.

Works well, but not totally goathead proof
by Rick

Fall is goathead season in southern California. I had 6 or 7 punctures on my road bike in two or three rides, so I installed Mr. Tuffy's with a new set of tires. All was good...for a while. This morning I had two flats...one front, one rear, and in both cases the dreaded goatheads pierced the tires, Mr, Tuffy's, and tubes. They repel 95% of them, but after my experience this morning, I realize there is no 100% protection from the dreaded goatheads, short of armor plating. But they can probably penetrate that, too!

I bought a set of Mr. Tuffy tire liners in May, installed them in June, and new tubes in both my front and rear tires were punctured by a small, V-like point at the end of the bend or crimp in the tire liner. Today, July 16, the Mr. Tuffy tire liner rubbed another hole into a new tube because the liner slid out of its centered position and its edge became a point that punctured the tube. I've never had this happen before, and at this frequency, with a Mr. Tuffy tire liner product. I'm not happy that it cost me approximately $24.00 for three new tubes.

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 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...)
