Self Sealing Inner Tubes: Do They Work ?
Hello,
Concerning those "Self-Sealing" inner tubes:
Do they work ?
Worth going to the trouble to find them when putting on new tubes ?
Any thoughts on would be most appreciated.
Thanks,
Bob

sometimes .. but if they don't, the sealant, prevents a normal patch from sticking.
extra thick Thorn Resistant tubes are worth a try.

What kind of bike?
If you're running fat, low pressure tires, self-sealing inner tubes will repair small thorn pricks. If you have skinny, high pressure tires, not so much.

I don't like them. I prefer to spend my money on a good quality tire with Kevlar belts. However in a couple of cases I have used them with mixed results. Biggest pain is if you want to let air out of the tire, you have to pull the valve core and you get the slime all over the place.

They've held a 1/8" gash for me but only just well enough so that I could get home.
They work great on small pinpricks. If you need to use a patch, you can just wipe the sealer off on asphalt, while trapping what's left inside the tube away from the puncture.
I buy the sealant separately some of the time and add it to ordinary tubes. This does not work so well with a presta valve.
Thicker innertubes will add a lot of rolling resistance.

read a story about how difficult it was to get neon green Slime sealant off the Cat,
when the tire Blew off the rim, and Kitty was collateral Damage.

It depends on your situation and what you mean by work. If you ride in a area where you get a lot of thorn flats (small sharp punctures instead of cuts), and rather than patch your tubes you just throw them away, then definitely. If you run tubular and so can't patch, it might be worth it to you. Pretty much a must with tubeless tires... In CA I used to run it in my mtb tires. Tried and abondoned it in the road tires. Now in New England I don't use it. YMMV.

Not well and they are more trouble than they are worth. For teeny tiny pinholes that create slow leaks, they do work. Anything bigger just gets sticky crap all over the tire, tube, wheel, and whoever the poor slob is that has to replace the tube. Valve stems get clogged with the sealant too. Like fietsbob mentioned, wait until one explodes if you want to see a real mess.
The tire sealant goop works much better on tubeless tires like those used on ATV's and lawnmowers.
