worried about slime

The stuff distributes around the inside of the tyre as the wheel rotates and remains liquid until there is puncture when it solidifies in the hole. AFAIK, the reason for the valve being at the top is to make injecting the stuff easier. The stuff I have recommends removing the valve, injecting the gloop, spinning the wheel and then replacing the valve.

As you have correctly said, the tyre only ever gets flat at the bottom. Gravity will ensure that's where the slime ends up, so you'll be fine ;)

But the chances are you won't need put air in the tyre so often as the Slime also reduces the natural porosity of the tube ... and taking the valve out to clean it once every so often (not that I have *ever* had to) is a small price to pay (IMHO) than even getting one puncture.

I typically run slimed tubes in Schwalbe Marathon / Plus (puncture resistant) tyres on all my bikes (and tandem) because I care less about good rolling resistance than I do getting home with no (puncture) issues.

YMWV of course. ;-)

Good luck with removing a Presta valve!

Never underestimate what can be accomplished with a pair of mole grips and a hammer.

The slime must react with the air presumably in a short period of time in service to seal a puncture, but what makes it possible for it to be introduced to the tyre and not react with air in the process or with the air in the tyre when it is reinflated?

Slime is an anagram of smile so I'd not worry! Brian

I did?

What part of 'Slimed' didn't you get?

Like I said, YM*W*V, because that's your MO. ;-)

Despite them suggesting it can be used in car and motorbike tyres the small print says....

"Use as a preventative/repair measure in all NON-Highway vehicles"

The two statement aren't contradictory.

The first statement is a suggestion. That it CAN be used in the appropriate circumstances.

The second statement is an exhortation that it SHOULD be used in ALL non-highway vehicles. The emphasis here being on the word ALL.

The implication being presumably that there are some road going vehicles where its use would be unecessesary, or impractical. But that this limitation doesn't apply to non-highway vehicles for some reason or other.
