Mr. Tuffy XL Series Tire Liners for Fat Bikes

Western was easy to order from, and Mr. Tuffy has proven its worth. I installed them myself inside Kenda tires on my RAD City Power Bike. I watched a video first, and because the Kenda tire was bigger than that shown in the video, the install was easier than I expected - smooth and complete. Up until Mr. Tuffy, I'd experienced a front flat and two rear flats since purchasing the RAD in late August 2018. Mr. Tuffy does seem to have slowed down the speed a tad, but there have been no more flats, the ride feels more secure, and that's riding on gritty, winter crud in the bike lanes where the flats occurred. Western shipped Mr. Tuffy sooner than I anticipated. I bought a set for my wife's RAD City too, but because she hasn't had a flat yet, she didn't want me to install them. One more thing. I'm 74 years-young, and if I can install Mr. Tuffy...well, maybe you can too.

a little bit hard to insert properly but once in they work great.

I ride the fat tire bike on a lot of different terrain and had a couples of punctures in the past, So far no problems since installing the liners.

Double skinned these liners inside a 29 Big Apple 2.35 rear due to thorns. Stuck them together with thin double sided adhesive tape to hold them in together evenly during installation. Running BigBen 2on front with GreenGuard. The Apple needed more protection being on a norco vlt r2 ebike rear. Changing the rear is not quickeasy.

High speed no problem. Top speed of 57.7 kph downhill into a bend stable.

Make sure you cut overlap for better balancestability at speed. You can keep the excess in your spares kit as a worse case emergency sleeve. Installed just one initially leaving overlap and bike stability was impacted negatively above 40kph. Hence cut them

Apart from that initial learning curve they've proven to be bullet proof onoff road.

Simply rolled Mr. Tuffy XL liners around my 4" wide tubes. I like the ease of installation (once I removed the rear wheel of my electric bike, that is). I had a nail puncture flat the week before I purchased Mr. Tuffy. I had my tubes filled with slime but my tire still went flat. Fortunately I was near the end of my ride and only a half mile from home. I knew I needed more protection especially because it is very time consuming removing my rear wheel on my electric bike and I did not want to flat 20 miles from home. I chose the Mr. Tuffy product and haven't looked back.

I'm angry that I relied on the tire sizes listed. These are only 2.5" wide, although green liners 2XL are listed to work with 3" tires. What I needed were the tan 3XL liners, but I refuse to pay for return shipping and I won't buy from a company that doesn't provide free shipping for returns ever again.

I bought lime xl liners for 3" tires, but the liners are only 2.5" wide. I wish that I had bought the tan liners instead while they were still in stock... Don't trust the guide, they run small width-wise,

I use these in mountain bike tires, both knobbies and smoother trail tires, the inconvenience of flats is greatly reduced and on a plus or fat bike the added weight is negligible.

These were delivered to me quickly & brand new as expected

I installed them about 300 miles ago and have been very happy
