What do you guys think? Any of you guys/gals got 'em? I've read where they if you don't install it correctly that it'll end up causing a flat... but when installed right... it's worth it?

I not watching on how light my bike is or if it's going to slow me down... Any good experiences? I've got the tuffy on my mtb but haven't road around it as much as my road bike to see if it works. Thanks...

They are crap.
Even when installed correctly they will still cause flats.
However, after you put them in the tire, go over the seam with a few pieces of duct tape. Or run a thorn proof tire as well, or both.

If you can avoid the pinch flat dilemma with tuffy's, and you don't mind the weight, then go for it.

Other than that, these things should be pulled off of the market.

Tuffy's have never caused me flats = give me a break. I love em - they've reduced my flat frequency to next to nothing.

Mr Tuffy's went out in the late 80's, I use a tube sealant, like Slime

They were already installed on the used Cannondale I bought last year. I've ridden that bike almost 3000 miles so far . . . zero flats.

instead of mr tuffys (tuffies?) on your road bike, do what i do

get some extra thick tires (like the bontrager hard case) and then take an old tube and cut out the valve stem and line your tire with that.

Thanks for the responses everyone...

I didn't think about Mr. Tuffy's and pinch flats. Also, for that Slime stuff... can that get messy?

RBI... on the Bontrager tires you mentioned... I read a couple reviews on bikeforums and is it really as hard to mount the tires as other reviews have described? Wrestling match?

Thanks in advance...

Another simple, and cheaper fix is to just line the inside of your tire with some duct tape and electrical tape. The problem with the tire liners is that they leave a seam . The liner has to stop somewhere. Even though they are tapered on the end, that just makes the end of the liner sharp. If the tire flexes in that specific area from let's say a curb or rock it can cause that seam to pinch the tube.

If you are just commuting and keeping both tires firmly on the ground without the proper air pressure, they might last a long time. I have never gone more than a week without getting a flat due to pinching from the liner seam. In fact I was puzzled, as to why I was getting flats with tffy liners until I realized that it was the cause itself.

no, ive never had a problem mounting those bontrager tires onto my rims. i have them on both my fixie and my road bike. i think they are perfect.

slime doesnt work in a high pressure road tire at all so fuck that noise.

Nothing like slime exploding all over your frame, wheel, and everywhere else. On top of that, it sometimes seals off your valve. Then you can't air up.

I've had pretty good luck with slime in high pressure tires.

It doesn't mean that you don't get flats - I would still get the occasional flat, but just pump it back up and off you go.

When I finally had to take the tire off of my wheel to replace a busted spoke, I counted 7 seven leak spots where the green slime had sealed up a flat.

I still carry a spare tube though - if you hit a piece of glass, slime ain't gonna help you much.

ever since I installed mr tuffy liners on both my fixie and mtn. bike I've had zero flats since. going on one year with ZERO flats. just depends if you're putting them in correctly. i think they're great.

To the guys that has had success with the liner... do you guys just install it as is or do you tape up the overlapping area?

installed as is. no duct tape. make sure you buy the right size of course, and DO NOT cut off excess liner that may overlap. it takes the tiniest bit of finesse at first to get it in, but once you get it you're fine.

I ride Specialized Armadillo tires on my fixie and have had 1 flat in 1 and half years. I ride all over the city from the valley to hollywood. Attend 90% of MR and Hollywood Ridazz and commute to work.

I see lost of glass and other unfriendlies. I've plucked chunks of glass and bits of metal from the tire with no puncture.

Armadillos.

I just installed a Mr. Tuffy in my rear tire last weekend. 50+ miles, no problems yet. Really annoying to get installed properly.

I only had one liner, so for the front I doubled up a piece of rubber-backed Cordura fabric all the way around. I tried to pierce it with a push-pin; seems tough enough to repel most road hazards that make it through the tire.

On the other hand, prior to the tire liners, I rode for more than a year with only one flat, and that was a pinch due to under-inflation.

my solution on my fixie was to install thorn resistant tubes, you know the double thick ones, and run a set of kevlar lined tires, my tires have gouges all over them, and I've only had one flat in 9 months, from a valve stem that had just had it (the tube was 6 months old).
