Review on 🚲 Mr. Tuffy Fat Bike 4X-Large 26/29 x 4.1-5.0" Teal Tire Protector by Jeff Sorensen

After suffering a puncture from hitting a flat tire, I first replaced the bike tube with a sturdy one and then added this Mr. Tuffy. Since then no problems. My bike has fat 20" tires, but Mr. Tuffy only makes 4" tires for 26" lengths. As it turns out, this isn't a problem. I simply cut off the excess length with sharp scissors. Supposedly this liner added a little to the rotating weight of my bike tires but I didn't notice. Rather, he added more security to my trip, knowing I was far less likely to be stuck miles from home and having to do complicated and time-consuming pipe repairs.
