So I want your advice on tire liners , I have the rhino dillos for my tires but they overlap about 2-3 inches I read somewhere I should cut then to where they are even inside the tire, then I have heard just let them overlap it willl not hurt anything.

So looking for a tie breaker or so , really looking for the proper way they should be installed.

thanks

We always let the liners overlap a little bit. The overlap is opposite the valve. One potential in cutting the liners shorter is that the ends can errode through the tube. Any sharp edges only hasten this. I never liked selling liners for that and a few other reasons. The last thing i'll mention is that many liners will take a "set" after installation and use. So getting the liner straight from the get go is essential. Of course without Xray vission that's hard to know. Many times I have fixed a customer's flat, found that it had liners and that the liner was snaking back and forth, exposing some of the tread section. I try to show the customer because the liner won't ever be placed straight again and we'll get the blame for the next flat. Andy.

I bought a set of stopflats2 and the directions explicitly stated to let them overlap and don't cut

I've had similar snaking issues with tire liners. At one point, I had two bikes with liners. On one bike, The liners stayed straight in the tread line. On the other bike, the liners would work themselves out of position, snaking back and forth as Andrew R Stewart put it, so that the liners were not under the tread in some places. I ended up taking that set of liners out and putting puncture resistant tires on that bike.

I don't cut my liners down, but allow them to overlap.

I used Mr Tuffy liners for a couple of months years ago but not anymore. The reasons are 1) the edges wore away the tubes after a time, thus causing flats, and 2) they prevented a few flats IMO, but their effectivity was very limited.

After having the end wear a hole in the tube, for customer installs,
I use the Shop Bench grinder, & taper the end thin, and load the tire up with Talc powder..

But really, now, I Just put Schwalbe Marathon Plus Tires on,
the same effect is outside the casing, then. Under the tread.

I do this.

I also do this.

I can feel the lump in road tires over 100 psi or so, so I like to cut those. Last pair of Mr. Tuffy I got were cut off square, so I had to adjust to that. I actually rounded off the corners when I cut 'em, not a complete arc like the old Mr. Tuffies, just rounded corners. I sand the inside cut edges just by rubbing them on the driveway a bit.

Sometimes I'm lazy and just run 'em overlapped for a while, but usually cut them after I eventually get a flat.

I've been lucky. Have not experienced a great deal of rubbed-through holes from the edges of tire liners. I vaguely remember one back in the 1990s on low-pressure MTB tires, but very vaguely.

thanks for the replies, now when installed will I notice a difference in the rolling resisitance or will the tire seem out of round if the liners overlap?

FWIW, IMO this would be counterproductive because it would allow the tube to move against the edge and thereby wear. If the tube is stuck to the liner and can't move with respect to it, it can't wear. It may fatigue at that point, but I rather doubt that too. I don't think the tube moves at ~100 psi on a road bike either way. I believe it to be more of an issue at the low pressure in mtb tires and with the greater deformations they under go.

Also FWIW, I liberally talc my tubes and inside of the tire for the purpose of making them easier to install/remove and reduce the chances of pinching the tube in the process.

Hmm maybe thats why I dont experience rubthrough problems that others do. I dont powder. Then a year or two later when i get a flat I have to peel the liner off the tube - sometimes they're really stuck good.

I run 700C Mr. Tuffys, and am very happy. I recall the instructions saying to let them overlap. It would be nice though if Mr. Tuffy would taper his liners for us. That said, I have not had any issues with tube-cutting or bumpy rolling.

I did once get a flat due to the above-described "snaking", it can be tough to get them to stay straight. What I do is put one bead on the rim, then put the liner in (overlap across from valve, as suggested above), then put in a slightly-inflated tube (just enough to make it round not flat) and with one bead out, go around and around trying to get the colored edge of the liner to run straight (and just hope that it's centered!!) Push a little here, pull a little there, maybe go to the overlap and pull it a little tighter. When I'm satisfied, I close up the bead, pump it up, and pray.

After my first snaky install and flat, and installing more carefully, I have had good success (or good luck) and no more flats. I'm maybe half-way through my tire life, so it will be a little while before I have to mess with it again.

I have bought a pair of the rhino dillo liners , new tires,tubes come in monday so will install then. thanks

I used Mr. Tuffy's in my rental bike fleet for about 3 years. Never trimmed them, just overlapped. 8 bikes, no issues.

Couldn't you use rubber cement to glue the liners in the inside of the tire to prevent from moving around?
