Speed Demon I never mentioned that I have fitted Bridgeport valves and Bridgeport valves are not the issue if you read the thread from the start you will eventually realise this. What I was commenting on was the fact that you do not need a perfectly flat surface to fit valves to and all valves have a rubber seal that fits to the rim. The bolt in type most commonly fitted to these rims have rubber sealing washers both for the inner surface and the outer one although I concede that there may be some valves out there that don't but this is where common sense comes into play when choosing which valve to use. The ones from MB fit perfectly and don't require any grinding of the rim what more can I say?

It's not a problem - I think we are all trying to help.

I was simply pointing out that for some valves- like those being discussed - the absence of a flat-faced hole, or indeed a hole of one of the conventional sizes, does make a difference.

While you have not had a problem with your bolt-in valves so far (I think that bolt-in are probably the better solution compared to pull-in for ScootRS rims) I'd advise checking/replacing the rubber sealing washers at least at every tyre change because these have been known to perish over time.

That's certainly good advice Speed Demon as the average mileage that scooterists do ,a rear tyre could last2 or 3 years , but the front ones could last almost indefinately without wearing down so rotate them front to back etc and if when you check the tyre it has surface cracks due to hardening it may well be time to think about changing the tyres and valves for the sake of £30- £40 Especially when you consider that small tyres &wheels suffer a lot more than bigger ones when hitting the all too common pot holes that have appeared around the country.
