thread Not with snakebites
in fact it might make them worse by raising the tube. Rim tape will only help with rim punctures.

The only solutions are more pressure (I'd run 25s at over 100psi - more like 110) and making sure he is seating the tyre properly (not catching the inner tube at all).

Weldtite used to make anti-puncture tape which was like rimtape, but went between the tube and tyre instead, but I do not think it will help with snakebites either (and it looks as though it has been discontinued anyway).

I am assuming he mounts his tyres correctly, so this is just egg sucking, but inflating them to about 20lbs or so, then spinning the wheel and feeling for irregularities is a must for high pressure tyres. I have had too many blowouts and pinches when inflating, due to idiotic Manley error, not to do that every time.
permalink I know nothing about road bikes,
but I've used special tape that goes between the tube and the tyre, that is made out of special goo, that reacts to any air being expelled from the tube, and cleverly seals the gap.
It's like those MTB inner tubes you get that have liquid gack in them that solidifies in the area of any puncture.
permalink Yeah, that is kind of what the Weldtite stuff was like.
It served dual functions - had less chance of a puncture (because there was a barrier) and attempted to close up punctures - fine at 30PSI with a Swampthing, probably fuck all use at 110PSI in Gatorskins.

If you are as fat as I am then 20mm tyres are not worth the effort, they end up being as wide, if not wider, by the time I compress them.
