Tire Liners

[PedalUma]

For some reason we have maturing yellow star thistles all along paths and where everything else has not developed RoundUp resistance. The thorns have microscopic barbs and they break off inside the rubber of the tread only to continue the one-way journey unseen.

Around here we call that a Bull Thistle, we cut down every one we find, No Cal Red Bluff area had miles of them, called Star thistles,
never had any problem with tube/tire problems, that I remember.

I haven't seen the Bull Thistle where I ride in central NM? We have a lot of goat heads and low to ground paddle cactus hiding in the tall grass/weeds being high desert (+5000 feet):

Internet photos below and the reason I like some type of liner and/or sealant. Can be a lot goat heads even on paved bike only lanes and unpaved improved bike trails.

I've had the Flat-Out in my first ebike since Feb. 2023 and it's been in my new ebike since May 2024.

I can still feel it in sloshing around in my new ebike's tires (27.5 X 2.80) when I spin up the wheel in the air. (I don't feel it when I ride?)
There's half a quart in each tube.

That's why I leaned towards FlatOut... Long shelf and service life.. Supposedly

Flat Out states a 10yr operating/shelf life on the plastic jug I have.

For anyone thinking of using Flatout, DON'T Get the passenger vehicle version.

It's for high speed driving and it doesn't work as good, especially in higher pressure tires. (I think it's a lot thinner?)

Your need really depends on your surroundings. If I didn't have goat heads I would not have needed Tanus liners IMO. Since we do have them, I would not be riding without them. As a kid in the 70's we just had to get used to fixing our flat tires, but I also think our bike tires were a bit tougher back then too. Seems the rubber these days compared to 50 yrs ago is a lot softer, but I could be wrong..

I forgot to add that I also run these HD tubes, that about 3x thicker than standard bike tubes, they are kind'a expensive, but for the way
and where I ride, along with Sportsman Flat Out, they are worth to me, imho. yrmv

We call them thorn resistant tubes. They are very heavy, but they help.
