General Cycling Discussion - Mr.Tuffy tire liners instal

Ordered them for more protection on my tires and I need some details or tricks on how to install them.

My install now:
Tire off rim
Sand, cut and fit liner
Contact cement on liner and tire
Apply liner
Place tube in tire, inflate lightly
check liner
Place on rim, and fully inflate while squeezing tire to fit tube

does this sound good? Or am I doing it wrong? Any instructions for me?:twitchy:

I just stuck mine in the tire, made sure it was lined up, put the tube in, inflated a touch and made sure things were straight, then mounted and inflated. I didn't mess with cutting, sanding, or gluing them in place. They seem to work that way.

I used the bench grinder to taper the ends.. but they still move against the tube with every rotation
so will abrade the tube in time, heavy thorn resistant inner tube will slow this.

I buy Schwalbe Marathon plus tires now. .. instead.

If possible, buy it in the right circumference for your wheel size instead of cutting it. Sanding, etc are remedies to fix the problem you'd create if you had to cut it.

I also wouldn't cement it to the tire. It will stick to the tube on it's own.

Just get the correct size, put it in, and if you run low pressures replace it before it starts to crack.

That's why I don't think you should use talc. Without talc the liner seems to get really well stuck to the tube and stays there, but with talc it can move and begin to abrade.

Problems I've had with tire liners are:
-I cut end to fit small diameter wheel and didn't taper end. End cut into tube.
-I removed tire liner. Road debris cut into tube.
-Switched to wider tires with same liners. Got puncture through side because liner was too skinny.
-Used extremely low pressure for winter traction. Noticed cracks in liner after a few years of use, but didn't replace. Cracks cut into tube.

I think a liner works better than a built in puncture layer because they can be like a football "defensive linebacker" and react to puncture threats: if a sharp object begins to penetrate then the liner moves further in to continue resisting the sharp point. The downside is that any movement will cause abrasion over time...so one needs to be mindful of things which may contribute to unnecessary movement such as excessive tire flexing at low pressures or lubricating powder.

I've been using tire liners since the early '90s. AFAIK I've never had a flat as a result of the tire liner cutting into the tube. I never use talc. When I've replaced tires and tubes I've noticed that the tube is always stuck to the liner perfectly, so there's no movement that can cut the tube.

I've had 2 flats cause by Tuffy liners. Even after sanding, trimming, positioning, and placing tape over the edges. One was on an organized ride.:mad:

Much better luck with good tires minus the Tuffy.

Thank you all. I'll try my luck I got some 27" 1 1/4 for my well same size tires with thorn proof tires. I just didn't want any flats, I don't like them and out in my roads, I get them all the time.

I use stopflats2. They have an awesome lifetime guarantee. I was touring and at the end sent them two liners with 5 punctured tubes and they sent me 2 brand new liners and 5 brand new tubes to replace it. I should mention that I was using my crap stock tires instead of upgrading and the punctures I did receive were long and heavy duty nails.

Stopflats (not sure if tuffys have the same recommendation) advise to NOT cut or sand the liner. doing do will increase the chance of flats when the liner cuts through the tube. The liners come pre-tapered. I didnt use talc, stuck put them in and inflated. After a while, the liner sticks to the tire enough to not move but can still be removed with minimal effort.

I have been experimenting with graphite lubricant between Mr Tuffy and the tire. Theory being Mr tuffy should not move with the tire but with the tube. If you put graphite on the tube it becomes a horrible mess if you have to remove it.

If you put the graphite in there then how can you prevent it from getting between the liner and tube? I can't think of a better way to mix something up than inside a tire.

Here is a YouTube video of how I do it.

Don't know if this is in time to be of any help but here (http://www.bikeforums.net/showthread.php/708735-Tire-liners?p=12713690&viewfull=1#post12713690), is what I did using Slime liners purchased at Wally World.

Good luck!
