High speed tyre fail?

[ducatilover]

Would a tickle of thread tape help instead of an o-ring?

Just be cautious of heavy caps. Like thee light up ones. They have been known to pull a stem out.


Stupid phone / Tapatalk, apologies in advance.

Ordered myself some cnc ones with o rings.
Rear wheel wibbly at 300 was not very much fun.
Guess im lucky it wasn't the front.

Might take a some spares next time and see if anyone has some missing.

Sounds like you just need some CNC lightweight valvey doodads, resist the centrifictional forces, save not only weight, but unsprung weight too, and not only unsprung weight but rotating weight at that, shave literally infintesimal fractions of a quarter mile run off your time. No vin deisel monologues for you while you head down the strip.

What I needed was for the rim to get damaged and talk the wife into a set of BST carbon race (safety) wheels.

Main reason is if I get nice ones im not likely to forget to put them on after checking tyre pressure.

Yeah Google that shit and decide whether you want to run BST on the road

I couldn't afford BST anyway. Its just so much money that could be spent on other things.

I had this issue on the GSXR once after fitting a new tyre, was worried as mate had dented his ZXR front rim on that poxy BP entrance at Howick...
Shop pulled it off and remounted with some kind of bead sealant which cured it. Next tyre changer cried about the mess and didn't use it, haven't had problem again.
Maybe its a quality control issue with the odd tyre. Was only quick road use too, not track stuff.

Wonder though with how much the centre expands at speed that its plausible for the bead part to be doing similar, even a fraction would leak air.

How old are you valve stem outers? Mechanic replaced my rear one, few tyres ago. Not much room to get air line in so was always getting twisted a bit.

Something from trucking world, have had the longer valve stems (about two inch) get cracks. Even top of the line Alcoa allow wheels fatigue crack with age, had one replaced on steerer at about 800,000km.

Bikes under 2 years old on its original tyres (rear is due to be replaced 4tho km now)
Tyre had about 1 pound once cooled down and was still beaded. Inflated and holding.
