tire liners?

i'm so sick & tired of flats! do these tire liners really prevent flats, or is it a bunch of hogwash? oh sure the sites that sell them say they stop flats, but i would like an un-biased real world opinion from people who use these. it's hard to believe that a strip of plastic as thin as scotch tape will prevent a piece of glass from penetrating your tube. the bike paths in our city are filthy. glass, & debris, & just about anything litters them & the cities don't care to clean them up. just more people who care less about cyclists....

What's the cause of the flats you're getting? Are they really punctures from glass and debris? Or are you getting snake-bites? Or do you have a rogue spoke sticking past the rim-tape?

The combination I've found that worked well was an Armadillo tyre in 28mm so I can run lower pressures. This stands up the tire less on an piece of glass, the tyre wraps around the object instead. Less pressure on the casing at that point too and less susceptible to penetration.

Then I add a kevlar liner, use a thorn-resistant tube with the thicker layer on the tread. Add some sealant slime and I'm invincible!!!

I havent had flats since I put in Tuffy liners. The tires ride better than the Armadillos and with the liners they are still lighter.

Mr. Tuffys do work.

I was a messenger for 1 year in DC and 6 months in NYC, used Mr. Tuffys the whole time. Never had 1 flat tire.

I have used them on my commuter ever since, always on urban streets full of broken glass. The only time I got a puncture flat from debris in the road was once on the Brooklyn Bridge, I ran over the heel of a shoe that had broken off. One of the shoe nails stuck in my tire, and the Tuffy protected the tube. But, the heel then rotated around and jammed in my fork crown, and another nail stabbed the tire from the side.

Two months ago, I got new tires (real cheap-o's) and decided to skip the Tuffys. I got four flats in two weeks. Little bits of glass and, in one case, a small pointy stone stuck into the rubber of these POS tires. So, I put the Tuffys back in and haven't flatted since, still using the same tires and picking the glass out of them.

Mr. Tuffys are not expensive - ten bucks, and they do not wear out. One pair can last you a lifetime.

Tire liners like Mr. Tuffy work. One bike has the slime tire liner the other Mr. Tuffy. I have had 2 things penetrate Mr. Tuffy while riding. A very thin wire and a very thin piece of glass. Correct tire pressure helps. The thorn proof tubes help too. For some reason, the bike shops won't sell thick tubes. I buy them at Sports Authority. For me, flats occur in the rain or snow. I think the wetness causes tiny sharp things to orient themselves point side up. I also had a flat when a bent cotter pin sliced through the sidewall where Mr. Tuffy wasn't. I did an experiment with a Mr. Tuffy strip. I put it in a tire and put the tire on a nail sticking through a board. I stood on the tire and gave a little hop. The nail went through the tire and through Mr. Tuffy and into my flip-flop. I made sure the nail point wasn't longer than the depth of the flip-flop but the foam in the flip-flop compressed and I felt the point. The Mr. Tuffy-Thorn Resistent Tube combination isn't perfect but it seems to make the time-between-flats longer than the time-between-tire changes.

i just purchased a set of armadillo kevlar lined tires. the bike shop manager told me that those liners do work, but are extremely hard to install, & if installed incorrectly, can actually cause flats. he recommended the kevlar tires which already have that liner in the tire itself. the armadillo tires are much harder then my old tires which are very soft rubber. do they also make tubes that are lined with kevlar?

Warning, grumpy message:

Extremely hard to install? You line the tire with them. I'd be skeptical of a bike shop where this is considered extremely hard. Sounds to me like the manager wanted to sell you 40 dollar tires instead of 10 dollar liners.

Sure, Mr Tuffys can cause a flat if installed incorrectly. Tires can also cause a flat if installed incorrectly, and tubes, and rim tape. All of these things need to be installed correctly to work.

Okay, having said that, I've heard good things about Armadillo tires, and you've probably solved your frequent flat problem. I don't think there are kevlar-belted tubes because the kevlar wouldn't stretch with the tube when you pump it up with air, and it would make the tubes very expensive.

I have been riding with tuffy liners for 8 years now and I will swear by them. Best way to apply them is first sand paper the side of the liner that will go against the tire, then apply rubber cement to the center of the tire and let dry, then stick the liner on the tire. Afterwards I usually place a piece of duct tape on overlap of liner. That's how I do it. This way if you had to fix the tube by chance the liner will be affix to the tire without falling out.

--- I will offer my experiences and let you draw your own conclusions. I bicycle commuted in Los Angeles County from 1972 to 1986. After several punctures I got some Mr. Tuffys and had no more puncture-flats.
Now I have SpinSkin Duro tire liners and have had no puncture-flats with them (yet). Those liners are thicker than "scotch tape".

I don't really think it matters, I've flatted with and without tire liners. Ruined a New Michelin tire with a liner after just two rides. Just my two cents.

I agree with the others that liners do work. When the rear wheel gets six months to a year old, you can extend it's life by using a tire liner. I do this with my street bikes and folders. However there are some problems with the liners themseves.

1. They tend to untrue the wheel --- I've seen the Tuffy tire liner untrue my wheel or create a wobble because it tends to push the inner tube against the wall of the tire unevenly. Depending on the wobble, you may have to true the wheel or live with the wobble. I've had an LBS try to fix this problem and could not.

2. Pinch flats --- I've had my share of pinch flats and discovered that you're supposed to allow the tape to overlap. The problem with this is the inner tub inflates unevenly from the overlap creating a wobble in the wheel.

I'm going to experiment with another liner that's thinner made by slime. I hope it works just as good as Mr. Tuffy without distorting the wheel.

I glue them on so that they do not move around and stay put and centered. Works for me, and some of my friends, so I know I'm not the only one.

It's a fairly thick plastic where one side has grip to hold onto the wheel. I say they are about 3 mm thick. I don't think you want a thicker plastic because it would weight down the wheel.

First off Slime Tubes do not work on road tires, they will not seal even a tiny hole above 65psi. Second of all by the time you combine a Mr Tuffy (110grms), a thorn resistent tube (150grms) and a tire (230grms average) your up to 490grms. When I lived in Goathead City and found that these buggers penetrated even the Mr Tuffy, that after I switched to Specialize Armadillo (370grms) and a ultralight racing tube (65grms) for a total weight of 435grms, my flats dropped from an average of 3 a week to 2 in 3 years and over 15,000 miles, and those flats were caused by a faulty tube and allowing a tire to wear to the tread.

o.k. i just installed the armadillo tires. they are awesome tires! why does everybody say these tires slow you down? i took off like a raped ape on the bike with these tires! no problem there. my old tires were 90 psi tires, & these 125 psi, so the resistance should be less with these i think. anyway, only time will tell how flat resistant these tires are. from what everybody says about them, they are very flat resistant. i also bought a small pouch which contains a small bike tire repair kit that fits neatly in the pouch, a co2 inflator, & some extra co2's. it's about time i have that equipment on board! anyway, my old tires are made of very soft rubber that punchures very easily. the tires i always used are available just about everywhere. they are just a generic tire with a tan sidewall & a lot of tread, but the treads on these wear very quickly. what do you want for $9.00 per tire! actually the tires look like good tires,. but theyr'e really just cheap tires. i never heard of the armadillo tires before & i wish i did. it would have saved me a lot of time. i changed these tires because of wear & flats so many times it's not even funny! actually the rear tire that just went flat was a new tire that i put on the bike at the beginning of summer & the treads are almost all worn off & the tires are very thin. it had a piece of glass from a beer bottle still in it. i'm sure the kevlar lining of the armadillos would have stopped that very easily. i just wish the city would clean their bike path for us. there's so much glass & debris on them it's not funny. i have to swerve into traffic to avoid all the crap on the path. what's wrong with that picture?

just a figure of speech! lol! a lot of people post that these tires have high rolling resistance & slow you down like your pedaling up a hill or something, but i can't feel anything. the bike goes like hell & coasts fine with no apparant drag of any kind. i used bottle dynamos for years, so maybe i'm just used to some drag. or i never really used good tires on the bike just debt. store tires...

I use a thin aluminum stripe between tube and tire. It works great.
