Mr. TuffyBicycle Tire Liner

I've been using Mr Tuffy since back when they came out with Mr Tuffy since back when it first came out when I started using it was around late '80s early 90s what I recall before Amazon even existed I bought it at the bike shop it has worked very well although it's not foolproof you'll still get some Flats every now and then but do remember it's the sidewall where is the weakest point if you know anything about bicycles and fixing them then this product is for you if you don't you're going to give a bad review and I seen that those are people who have no knowledge about bicycles but as for me I have digged out glass Thorns from the tire and the tire is not even flat now I have had flats for like I said the weakest points is on the side wall for the price and the budget this is a good product now if you want full protection TANNUS which is one that recently came out a few years back I put it on my e-bike now my backyard mechanic I learned how to fix my own bikes we back before YouTube I recommend if you want to go all out and spend the extra money TANNUS but as far as for the budget Mr Tuffy is the way to go like I said I've used them for a very long time BEFORE TANNUS came out and they protect the whole tire sides and top but expensive I still trust Mr Tuffy I've had less Flats with Mr Tuffy's since I've been using for the budget I will go with Mr Tuffy

I was getting fed up with punctured tires every few weeks, especially with the rear tire, so I decided to try the Mr. Tuffy tire liners.Recently I punctured again on a Sunday morning ride after 33 and a half miles, 400 yards from home.No big deal, it was a short walk. Front tire was completely flat almost immediately.When I got home, I found 2 small, but very sharp thorns embedded in the tire casing which had pierced the inner tube in 2 places.Here's the thing. I found 2 more, longer thorns embedded in the rear tire which was protected by the Mr. Tuffy tire liner which I had installed the week before.The weird part is I wouldn't have checked either tire if the front tire hadn't punctured. I was running 700x25c Michelin Pro 4 endurance tires @ 82 psi. I would recommend the tires and the tire liners.

I've only had this product installed for 9 days at the time of this review, so take that for what it is worth. I watched the available video tutorials for several different methods of going about the installation. I own a mountain bike with 29 X 2.30 size tires, so I got the purple stuff. I saw one person install the liner by fastening it into the inside of the tire with gaffer's tape, another put the tire on first with a totally deflated tube, and then installed the liner. The liners come with a slight curve that makes it obvious which side faces the inner tire. The solution I finally settled on, was to first take the end with the tightest curl, then apply super glue to about 1 1/2" onto the side that faces the inside of the tire, then hold it down while spreading the glue out evenly, making sure that it was both straight & absolutely centered, before proceeding with installing the rest of the liner. One really good thing about the liners, is that to a large degree, they self-orientate, and to a large degree self center. I then installed a partially inflated tube in order to hold tire liner in place. The mistake I made, was that I did not go back in by hand to make absolutely sure it was centered, before reinstalling and inflating, & I suspect that the main reason I got a flat, is because it was not perfectly centered. I just got done patching the tube, and this time, went in and made sure the liner was absolutely dead center inside. The liners themselves are fairly thick, soft & pliable, made to stretch as air pressure is increased, and I would consider them quite durable, and I would expect them to last several tire changes, as my tires wear out. As an additional precaution, I plan on removing the valve stems in both tubes, and then installing Slime Tire Sealent in both the front & rear tubes for added protection against things like nails & sidewall flats. Also worth mentioning, I did not notice any difference in riding after installing the liners, compaired to before the liners were installed. I inflate to 40psi, as I do not like riding on low pressure tires, and being a mountain bike with 29' tires, I am still getting what I consider a smooth ride, with the most efficient roll. If I have further issues with the liners, I will give updates. I absolutely would purchase these tire liners again. I do hate fixing flat tires, and more so, I do not enjoy pushing a bike several miles home.Update:After going back in & making sure that the liners were dead center inside the tires, I have pulled well over a dozen goat head stickers(three pronged stickers that are all over my area, particularly off road, that can have very long & sharp prongs) out of both front & rear tires, both without any flats, or loss of tire pressure. I've looked for higher quality liners, before purchasing this product, but could not find any. I would, & will buy this product again if I get an additional bike, and I would recommend this product as a first line of defense against flats. Also, I would recommend the installation procedure I used, however, I would be happy to know, & to learn of a better method of installation.
