Mister Tuffy

Dave Burgess in Alabama has been running these liners for
thousands of miles and has not had a flat tire where the rubber
meets the road. He has had side-wall damage. Who else has
used Mr Tuffy liners?

Here in the Phoenix area, when I was still riding mountain bikes, we would use Mr Tuffys, but because of the number of goatheads we were getting, but we decided to Go One size larger to help protect the sidwalls. You have to cut off a wee bit of the length of the Mr. Tuffy so that it will fit correctly, but that's no big deal. The one weakness we found was if we ran a very low tire pressure, the Mr Tuffy would sometimes shift it's position inside the tire.. So, since we didn't worry about rotational weight on the mountain bikes, we also added "Slime". That way we were protected quite well. Otherwise, we all felt that the Mr. Tuffy was a good investment. I don't run them in my tires now since I go off road very seldom and I have a concern about the rotational weight because of the nuts I ride with. Need to keep my speed up. Although, there are a few of the fellas than I ride with that still use Mr. Tuffy.

Safe Rides,

Well, Dave Burgess of AL, said that from TX to CA one may ride the
interstates. He did for thousands of miles and never got a flat. He
told me he pulled a tire with 90 holes in it and never had a flat with it.
Amazing.

The good news for me: I called mark and he knows all about it and
runs them in his tires. He also stocks them. He is building a bike for
me and is going to install them in the tires.

I was surprised, I thought I knew everything.

 

Buddy,

I have used Mr. Tuffy liners for years. I especially use them in any wheel I do not want to have to try and remove in the field like the rear tire on Laurie's trike and the Limo (I really don't want to have to deal with the rear tire of the Limo on the road).

The rotational weight doesn't bother me, the time I save not having to change the tube more than makes up for it.

 

Good news indeed. The off road fat tires will be bullet proof, and can
ride it on road in glass etc. Needed that back in the 1970's when my
boys were pushing the Honda 90 trail back in from the Bakersfield CA
sand dunes. The old bike is out here in the shed now with flat tires.

 

OK after THREE FLAT TIRES this week, I am ready to look for some help.

I searched our board and found that tire liners can help. Any comments good or bad???

 

Jon,

I've always ran Tuffy's in my DF bikes, and I had them in my ActionBent Jetstream. The only flat I got on it was due to a burr in the valve stem hole, which of course made the tube unrepairable.

My Linear had Tuffy's and no flats, even when riding off road. And I rode it off curbs, mountain trails, etc, absolutely no problems.

My RANS V2, I haven't put them in yet, but have had two flats, both front tire flats. So, I'll probably put Tuffy's in before too long.

Mr. Tuffy's are great (as I mentioned earlier) but do have one drawback, they protect the tread area but do not cover the sidewalls. If you need sidewall protection as well then look into something like SpinSkins. These are expensive though so I stick with the Mr. Tuffy's.

 

All of my flats have been at the very bottom of the tube where it meets the road. They look like hypodermic needle punctures. No tear or gouges. Sounds like Mr. Tuffy is in my future.

Other comments good or bad?

 

What tire U running? Sounds like U need a tougher rubber compound with built-in casing liner. Marathon Plus are near bullet-proof, but doubt they are available in (what do U need, 650 wheels?). Schwalbe Kojaks are available in some larger sizes. Solid rubber tires are always an option. Only adds about 10 pounds to the bike.

 

I have a 20 " front tire and and 26" back tire. It is the back tire that is causing me fits!!! I am running on Marathon tires. Don't know if they are Plus or not. I looked at the tires and they don't say "Plus" so I guess they are regular Marathon tires. That is the reason I got them. I wanted something sturdy.

Here's what I think the problem is. With all the cutbacks, the city of Knoxville has cut back on greenway maintenance. They used to blow off the greenways a couple of times a year. I haven't seen them do it once lately. I also suspect that the sweetgum prickly seeds which drop in fall (they have all those wonderful spikes on them) have broken apart and the thorny part is still on the greenway. I am doing my community service and picking them up in the tires!!! Usually when they start cutting the grass the lawnmowers also blow off the trails. Grass hasn't been cut yet. I expect my problem will be solved once they start cutting the grass!

Yesterday I was so frustrated, I took the back tire completely off the rim and examine the thread and then turned it inside out to examine the inside lining. I was looking for a thorn, piece of glass, a wire, ANYTHING!!! I found NOTHING!!! I didn't even see any puncture marks in the tire lining. So whatever is causing the holes, they must be tiny! Tiny but effective!

I think I am going with the tuffys and if that doesn't do it, I am buying a new back tire. Never had so many flats in my biking career!!! I usually don't get 3 flats A YEAR!!! Now I have hit that record in one week!!!

 

Never heard of Tuffy liners before. We need to get some before we start touring this summer. Had five flats on the KATY Trail last summer but most of that was because of a bad tire.

 

3 of my past 4 flats with the Kojaks were on the back tire that, altho low mileage, had been slashed and chopped by glass, etc. on the roads. 2 latest flats were at the same large cut in the back tire. I finally gave up and put on a new rear tire that I had gotten from Mark a while back. No flats in over 150 miles.

Some people swear by the Tuffy liners tho I've never used them.
