Optimized Mountain Bike Tire Liner and Bicycle Tire Protector – Fits 24", 26", and 29" Bike Tires Review

I bought this product because I thought it would help me avoid a flat tyre. There are many thorns in my area. Unfortunately nails don't help. For the most part it works, but still not strong enough. I'm still looking for the perfect seal.

Before I have them I have a flat tire every week maybe twice a week. it's been a nightmare since these were fitted, not a single puncture, but that's not normal, rides. This thing made the wheels a little unstable, it felt like the wheel was flat. But that's not the case. strange . but I'm glad to have it.

I ordered these for my kids in addition to other brands of different size bike tires. This brand was significantly thinner than other brands and I don't think they will stop a puncture. I thought I would save some money by trying this brand but in the end I think it's better to pay a little more for the Tuffy brand which seems to be a lot thicker than this brand.

I've used a similar tire sealant in the past that has worked reasonably well. But this version is too slippery and too stiff in width. It will not stay in line with the tire even when installed under a partially inflated tube. If you imagine a straight bob run, a good bob stays at the bottom of the ditch. This product is more like a drunken bob, sliding up and down the sides of the ditch. Absolutely useless.

I've had 2 flats in about 4 months so I put this product on both the front and rear tyres. A month after installation I had a doubly smooth ride. Then over the next 5-6 weeks I had two more flat tires on the rear wheel. I removed both earbuds and haven't had a single bowl for two months after removing them. Coincidence? (FYI, I've checked the rim and tire tread for dirt and other objects with each firmware and replaced the punctured tube with a new tube each time.)
