About 90% of my riding is on almost rock-free trail surfaces: clay, hard packed dirt, and loose sand. Those trails are either fast and flowly or extremely turny. For those conditions it is advantageous to be using 2.4" wide tires at low inflation pressure; 16 psi in the front and 22 psi in the rear. However, these woodland trails are littered with all sorts of thorny, brushy, broken branchy debris, which exposes my "soft" tires to a high risk of puncture.After riding all 4 of my bikes an estimated total of 112 outings with the Stop Flats 2 installed, I have not yet experienced a single flat tire due to puncture by a sharp piece of debris. Only a couple pinch flats and a lacerated valve stem during that time span.Installation Tip (with inner tube)StopFlats2 has a curly memory in it because it was probably coiled by the manufacturer for packaging too soon after it was molded/extruded. It should've been allowed to cool all the way down to room temperature before it was packaged. Consequently, it is a little tricky tucking it into the tire as, it is not limp enough; it wants to recoil itself when you attempt to lay it inside the tire. The easiest way to install it is to first pump just enough air into the tube in order to fill out the tube without stretching it; so that its shape begins to resemble a doughnut. Next, set the tube aside within arm's reach, and lay the tire flat on the floor. Carefully unroll the liner all the way around the inside of the tire. Be sure to keep pressing the liner against the tire so as to avoid or minimize the formation of geometric chords across the circle of the tire. The object is to have the liner form a circle in contact with the tire; not a series of arcs alternated with chords. Work slowly, and patiently, not hurriedly. As soon as you make the ends overlap, grab the tube and stuff it inside, still keeping the tire flat on the floor. Next, pump just enough additional air into the tube to expand it enough to pin the liner in place so that it cannot shift while you are manipulating the assembly for mounting to the rim. Run your finger all around both edges of the liner to ensure that it is aligned on the tire's centerline, before you begin handling the rim. ### ⭐⭐⭐⭐ The easy how to do it yourself review *by J***N on Reviewed in the United States on July 14, 2011* It seems like a good product so far. It is a fairly simple install. The liner retained a lot of memory when removed from packaging so it would coil up when I would let go of it making it difficult for a moment. If you only pop one bead off the rim leaving the tube in the tire (leave a little air so the tire keeps its shape) and just stuffing the liner along the rear helped me a lot. Afterwards put the bead back in the rim and inflate. My mountain bike came from the shop with a wider tire in the front as they should I still used the same size as the rear but if you are an anal rider you may need to order 2 different sizes I guess a back up could be handy. I rode a 40 miler after the install everything seemed smooth and balance seemed unchanged even when approaching speeds of 40 miles an hour on asphalt down a steep road. I live in the country and haven't had a thorn puncture yet. My bike has 29 inch wheels and is a hard tail and I could not find a great deal of options as far as liners go and this worked good overall. ### ⭐⭐⭐ I got flats anyway. *by J***R on Reviewed in the United States on September 29, 2011* I got flats the first time I went near any stickers, and just about every time thereafter. I now put three liners in one tire and got a puncture resistant tube, but haven't put it completely to the test. I do think this is the better of the designs that I have seen in liners. Still afraid of the stickers... --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/10896717-stop-flats2-29r-bicycle-tire-liner](https://www.desertcart.pl/products/10896717-stop-flats2-29r-bicycle-tire-liner) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
