Review on 🚲 Enhance Your Bicycle's Durability with Mr. Tuffy Tire Liner: A Key for Flat-Free Rides by Joseph Morris

I bought Tuffy 29 x 3.1 MR liner. They were 3.5 inches wide (which is what I want) but didn't look fat at all!

Does the description say it prevents punctures from spikes, glass and road debris? Riders who go hundreds or thousands of miles without a flat tire, but even my Mr. Tuffy 29 x 2.5-3, which looked a lot fatter than these, bursts easily when I see the green goo sealing a lot of holes in my tires . Not sure. If they've changed their composition or rely on slime to seal holes, "never got any flats" is true, but more so on slime than Mr. Tuffy. I can't figure it out unless all the drivers are on the sidewalk with the "Never got a flat" sign right now. me in the city
