If I get a side wall rip, and all the sealant in my tyre pours out on to the trail, is it going to kill all the squirrels?

How bad is a latex based sealant to the environment?

have a think about where latex comes from

you are not BP

poor little squirrels, tails all matted from all the latex

BAN TUBELESS TYRES I SAY

I've got a mental image of rubber squirrels bouncing about the place… (-:

The only info I can find about latex hazards (outside of NSFW applications) is relating to people who are allergic to the stuff.

Have a think about where crude oil comes from.

Actually, having never run tubeless I don't know much about them, but is there actually a risk of sealent "pouring" out? I assumed that it worked by coating the insides of the tyre and drying rather than sloshing about in there.

Have a think about where crude oil comes from.

Mostly from the sumps of MkII Escorts and Transit vans in my experience.

Cougar – it stays liquid until it clogs up a little hole.
If the hole is too big it stays liquid and just pours out, at which point a tube is used and the non tubeless converts laugh and laugh.

Right.

Isn't that terribly off-putting?

crude oil comes from trees ?! – cool, I think I might dig up large tracts of land to plant palms
