I am a roadie - cycle 40 - 60 miles per week.
I use Mr. Tuffy's "Orange" 700x20-25c liners. 100 - 120 psi in the tubes.

I have had nothing but positive results from Mr. Tuffy's. I live in New Mexico where we have these horrible thorns called "Goat-heads", the bane of all things pneumatic! Before the liners, I'd get a flat nearly every 3-4th ride.
I got Mr. Tuffy's and for the past 2 years, I've had - maybe? - FOUR flats. Three from small wire pieces from steel belts of tires, and one from a perfectly placed sliver of glass. NONE from thorns. From all the slashes I've had from the tires, I know I've dodged the bullet from glass many times.

There is no noticeable performance disadvantage - but then, I'm not the most competitive cyclist. If you're a gram counter and like stopping to change your tubes, do without Mr. Tuffy's.

One potential caveat: I have friends who swear their Mr. Tuffy's caused pinch flats (I just don't see how that can happen - but I know they wouldn't lie about it), but that's never been my experience.

I highly recommend Mr. Tuffy's!

I ride in NYC, and there's a lot of sharp debris on the roads here. Since I installed these tire liners, I've had exactly one flat, and that was from riding over a board that I realized (too late) had nails sticking up out of it. I've pulled chunks of metal and glass out of my tires, thinking surely they'd be flat in an hour, and had them be in fine condition the next morning. Can't recommend these highly enough.

Goat head thorns are my nemesis. Not one or two at a time, we're talking 60+ thorns in each tire. When it happens, it happens with a vengeance. So, I got the purple Tuffy's for mountain bike tires. My setup has 2.3" and 2.4" tires, and the purple liners are the widest available when I bought them in September 2011. For me, they are not wide enough. With a really wide knobby tire, there is a lot of area for thorns to find their mark, and especially with the lower air pressure allowing more deformation of the tire, the sidewalls are extremely vulnerable. So I just cannot understand why these widest of Tuffy liners are so narrow. They really need to wrap around the sides, but they don't.

The other problem with these liners is resistance to puncture. They just don't have much. For some reason I had assumed that twenty bucks for tire liners would get me kevlar. With super sharp goat head thorns, these "recyclable" poly liners are not "Tuffy"-enough.

Sorry to be the wet blanket, and disagree with everyone else, but these liners just don't do it for me.

If Mr. Tuffy ever develops a wider, stronger tire liner, I'd be more than happy to give them a test ride.

I use Mr Tuffy for commuting.

I start with kevlar, high thread-per-inch tires such as Specialized Nimbus EX Armadillo or Continental Top Touring, then line them with these strips, and I never get flats despite riding through many broken bottles.

Some say that the stiff Tuffy plastic cuts the tube and gives flats. I don't think so, but you can always bevel the cut edge using a belt sander or sandpaper or a razor blade, before you install them.

I have three road bikes in my household, each of which get 80-100 miles of riding per week, and all three are outfitted with Mr. Tuffy Orange (700x2_) size. These bikes are run along road edges, with normal due care taken not to run over things. Over the past two years, I have experienced 8 flat tires among the three bikes. In one case, a piece if super-thin wire poked in about 45 degrees off the tire centerline. The wire made it all the way to the tube, passing through the orange part of the Mr. Tuffy liner, (i.e. not the reinforced part). This would lead me to say the reinforced part is not wide enough.

All of the other flats were the result of punctures of slices that went through the (reinforced) grey strip of the liner. One puncture was some kind of sharp metal, which sliced right through the tire and liner and tube. Others have been surprisingly dull, rounded pieces of metal. Not sure if there is a strength specification associated with these liners, but they can definitely be punctured. The company offers a guarantee in the form of free replacement tubes, however you have to send in the old one and the liner I believe. For the cost of that shipping I could just go buy a new tube.

Despite the number of punctures I have experienced with these liners, without the liners I would surely have had more. I have pried many small bits of broken glass, thorns, and metal out of my tires with no tube punctures, so I guess they do help somewhat. I have decided to buy two sets of high-end Specialized Armadillo tires and just for grins, one set will get Mr. Tuffy liners, the other will not. The Armadillos are touted as super tough and puncture proof. We will see, I will report any interesting results later.

It is not an easy task to insert it and keep it centered in the tire.
I have the orange model with a 700 x 23 tire.
You insert it first in the tire then you put the tube in. This displace Mr Tuffy and with a 700 x 23 tire there is no room for one finger to recenter Mr Tuffy. It would be a good idea if Mr Tuffy had glue on one side to keep it centered on the tire. I read some review that Mr Tuffy pinch the tube, It can not if it is centered. I suspect that Mr Tuffy moved sideway during the installation.
