Stay Away from thin walled tubes. I always get the best thick walled tube I can find. As I run fairly fat tires. So pretty much had always bought ''separately'' and put a whole bottle in each. Many of the pre-slimed tubes have a miniscule amount of product in them In my experience. . My way has been bullet proof for me for going on about 30 years now. .
I cannot count how many times I made it home etc to see some kind of a projectile lodged in and it brought me home
fully.
Have pulled nails and large thorns out on many occasions with absolutely no repair necessary.

Of course one may have to air up again. I Ride it and it always stops leaking all together.
Have been on many a construction sight to have a wheel barrel party . Basically getting a frantic move on to set cement foundations etc. Every one of the wheel barrels owned by construction workers I have known all my life here live by it. Bicycle shop up the street from me has it by the 5 gallon bucket.
We have ground sticker thorns here. When you find a patch of them it is pretty brutal. I don't go out of my way to run through the stuff. Yet have no worry's about them at all ether.
These are guaranteed to wreck a wheel barrel party lol.

Dang things were a bad welcome to my child hood. While it is true that a good tire, liner and thick heavy duty walled tube etc can be enough. I will never take the chance having seen what my tires have casually survived with it.
Never did like tire liners though they messed with my ride quality In My Humble Opinion . Sometimes I like a tire to scrub the pavement with a little better flex. Folks have had awesome luck with tire liners. I just never came to them.
