If you don't race and would rather ride than change flats these liners are the way to go. I have them on all my bikes and I have only had 1 flat in 15 years. The flat was caused by a staple that went through the sidewall, missing the tuffy liner.

Simple and Effective
rating

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.

Works, but some things get through
rating
by Ben K

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.

Used This Tire Liner Product on Multiple Bikes Over 25 years

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
rating
by Rick
Cycling Enthusiast
Ventura, CA

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!

Mr. Tuffy tire liners previously had hard edges that historically caused flats. A significant improvement was the subsequent 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 slow leak and eventual 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. 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.

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 is achieved perfectly suc

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'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 have been using liners for many years now and very rarely get flats. The additional weight of the liners are not that noticeable and the peace of mind far outweighs the 50g per wheel.

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...)

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
