Mr. TuffyStandard Weight Tire Liner(Return to Product Page)

Goatheads were the bane of my existence when my son began riding with his buddies on trails near our home. These liners did the trick. Kinda heavy but worth it.

I've been using Mr. Tuffy's tire liners for quite a while with complete satisfaction. It's very rare that I'll get a flat when they're installed.

These bike tires liners work great no problem.

Put these in for winter riding and no flats so far on approx 1000km.

If you don't race and would rather ride than change flats these liners are the way to go. I have them on all my bikes and I have only had 1 flat in 15 years. The flat was caused by a staple that went through the sidewall, missing the tuffy liner.

I was plagued w flats on my commuter bike so I pulled the trigger on the standard wt. Tuffy's. It was easy to put on and didn't really notice additional rolling resistance (my tires are already large 700 x 42). I only have few hundred miles on these but wo them I'd had a flat by now so I'm sure these are working like it suppose to. I like them so much that I bought the lighter versions for my road bike. So if you're getting more flats than you deserve slap these on enjoy the ride.

Yes, it adds weight and works, but some things get through. I do a fair amount of riding in the dark commuting to and from work in the northeast. Riding to work one early winter morning, I picked up a rather large piece of glass that gave me a flat. Don't worry, I was able to make it to work.

If you ride in the desert and are not running tubeless tires, you will prevent most flats with these. They slip right in between the tire and tube and are self-centering. Make sure the tube is partially inflated. As a test, I tried to poke a sharp knife point through the liner (before installation) and couldn't. I've tried this test with other brands, and the knife went right through, just like a thorn or other sharp object would.

Mr. Tuffy's, good tires, thick tubes and a sealant like Stan's will have you riding flat free for months if not years.

I've used Mr. Tuffy tire liner products on both a road bike and mountain bike for over 25 years and have generally been satisfied with the product's quality and usefulness. However, it's still possible for a Mr. Tuffy tire liner to inadvertently puncture a tube.

This manufacturer's tire liner will generally block small, sharp items like a piece of broken glass from puncturing a tube, but the liner won't stop a larger, sharp piece of broken glass or any type of nail, for example. Also, given that the liner is supposed to be seated in the middle of the tire, don't expect protection for the tire's sidewall.

The manufacturer's claim that their tire liner will Absolutely, Positively not cause tube damage isn't true.

When installed, the tire liner must be seated directly over the tube and generally centered in place all the way around the inside of the tire wall. This process remains difficult to achieve perfectly so that the tire liner is seated correctly. Frankly, it's nearly impossible to get both the tube and tire liner properly seated together, especially when re-mounting a Michelin Pro 4 Endurance tire model. There's a slick, slippery finish to the tire liner that makes it difficult to keep in place while attempting to position a tube. So, the tire liner moves around a bit, can end up not being centered over the tube, and is instead pushed off to either side of the tire, and therefore may end up with a small bend or crimp in the edge of the tire liner.

If there's a small bend or crimp in the edge of the tire liner, the end of the bend or crimp forms a small, V-like point that rubs a hole in the tube and causes a flat. Mr. Tuffy tire liners previously had hard edges that historically caused flats. A significant improvement was the softening of the tire liner's edges so that flats wouldn't occur. However, a bend or crimp in a tire liner not perfectly seated can cause a punctured tube.

I bought a set of Mr. Tuffy tire liners in May, installed them in June, and new tubes in both my front and rear tires were punctured by a small, V-like point at the end of the bend or crimp in the tire liner. I've never had this happen before. I'm not happy that it cost me approximately $16.00 for two new tubes.

Nevertheless, I ride through a lot road debris on Pacific Coast Highway in southern California, and still believe this is a worthwhile product when its installation if achieved perfectly such that the tire liner is centered and seated correctly all the way around the tire.

I use the Mr. Tuffy tire liners inside a Michelin Pro 4 Endurance tire model on a 700x23 wheel.

I've been using tire liners on my bikes for 25 years. In that time I've had two flats, one road the other mountain. Before that I was having flats all the time on my road bike. One of the best investments you can make as a cyclist. I prefer them greatly over tire sealer which I have also used. Install them and forget them, unlike sealer.

I've used Mr. Tuffy liners for years now. Started out with the "slime" products that you squirt into the tube and found that a leak would cause a mess that was more trouble to deal with than just patching the tire. After I started using the Tuffys, flats have virtually disappeared. They come in a variety of sizes, but are easy to trim to shape with a pair of sharp scissors so you can get the perfect fit. Long lasting, to boot. Highly recommended.

I fixed a lot of bikes in my 20s, but now I'm 40, and I like having clean nails and dislike bending over for too long. Anyway, this worked to fix my husband's issue with flats and didn't require any goop or valve-stem removal or anything like that. We live in AZ and his first day commuting 5 blocks to work he got 4 holes from dreaded goat heads. And since we added these, he's had no flats in 2 months of commuting (though the goat heads are still there, trust me). So, these work great. Here's how I dealt with adding them to the tire:

1. Put one beaded edge of the tire in the rim.

2. Added the liner into the tire. I tried to hold it there with Scotch tape, which didn't work well because the liners are so slick. Duct tape would have worked better, so try that.

3. Fit the tube into the tire.

4. Squash the other beaded edge of the tire into the rim.

Highly recommend!

i have been using these liners for several years now and very happy with the results. Provided the tires are inflated properly the flats i do get are ones I deserve for example pulling out a 3 inch staple from my tire or other. these guys are really good and happy with the result. flat proof....no? Flat resistant.... yes.

I have read that some have challenges installing them, but its quite simple if you lay the rim flat after the tire is partially mounted and insert the liner and then tube. no big deal.

1st time used this, trying to reduce number of punctures. lots more junk in our streets than used to be. still have the product and actually still had a puncture from a center of tire (continental gatorskin) from a thorn. kind of mixed on this, believe it might move around the tire a bit more and I inflate before every ride.

Fall is goathead season in southern California. I had 6 or 7 punctures on my road bike in two or three rides, so I installed Mr. Tuffy's with a new set of tires. All was good...for a while. This morning I had two flats...one front, one rear, and in both cases the dreaded goatheads pierced the tires, Mr, Tuffy's, and tubes. They repel 95% of them, but after my experience this morning, I realize there is no 100% protection from the dreaded goatheads, short of armor plating. But they can probably penetrate that, too!

There's a much slicker, slippery finish to the 2019 Mr. Tuffy tire liner product I received that makes it difficult to keep it in place while attempting to also position a tube. So, the tire liner moves around a bit, can end up not being centered over the tube, and is instead pushed off to either side of the tire, and therefore may end up with a small bend or crimp in the edge of the tire liner.

However, a bend or crimp in a tire liner not perfectly seated can cause a slow leak and eventual punctured tube.

I bought a set of Mr. Tuffy tire liners in May, installed them in June, and new tubes in both my front and rear tires were punctured by a small, V-like point at the end of the bend or crimp in the tire liner. Today, July 16, the Mr. Tuffy tire liner rubbed another hole into a new tube because the liner slid out of its centered position and its edge became a point that punctured the tube. I've never had this happen before, and at this frequency, with a Mr. Tuffy tire liner product. I'm not happy that it cost me approximately $24.00 for three new tubes.

Have been using these since I first found them on Bike Nashbar co. in the mid 1980s. Never a flat since and I even lived off my 10-speed for three years when my car crapped out in LA. These even held air when I skidded through glass and worn out enough tread where the protector could be seen and it still held air enough to pedal home.

I commute to work six days a week weather permitting. I have three bikes with electric motor kits and do a lot of riding. Put tuffy tire liners in my tires haven't had a flat since. Had several flats before that. Good product. I ride 14 miles to work round trip daily. Plus other errand's everyday.

Bought this to use for a Florida bike trip that involved lots of shoulder miles and bits of vital strength around as well. No flats at all during the ride (others not so fortunate)! Highly recommend.

Use Mr. Tuffy in my mountain bikes for trail riding to prevent blackberry thorns from puncturing. I also convert on of my mountain bikes for winter when I install road tires but keep the Mr. Tuffy in to prevent punctures from road debris.
