Confusion ignorance High pressure tyre valves

Just had 4 new Vanco 4 season tyre fitted to alloy wheels by Performance Tyres, Bishops Stortford. They new when asked all about HP tyre valves, as they do subcontract fitting for Main MB Commercial Dealer.

Seek out a fitter who does commercial van fitting, or buy a set of TR600 XHP valves for them to fit. They are not metal on metal but have a HP rubber snap in fitment.

What a minefield tyre valves are. I have a slow leak on the front offside tyre. My local Kwikfit diagnosed a leaking valve but were unable to supply a replacement steel high pressure valve. They only fit rubber valves and knew that these were unfit for the pressure required but beyond that they weren’t prepared to help. They suggested I try the local ATS who they said fit a lot of van tyres.

ATS told me they wouldn’t be able to source a valve but would fit if I sourced one. I find this all pretty lame, there are thousands of motorhomes on the roads, presumably many of them require steel valves with a high pressure specification. But two major tyre fitting firms have essentially told me I’m on my own. Maybe I was unlucky with those particular branches.

I think I have three options: approach other tyrefitters until I find someone knowledgeable, or refer the problem to a Peugeot van dealership, or source the correct valve myself and get someone to fit it.
I’m tempted to take the 3rd option to avoid lots of running around and blank looks. The risk is that I get the wrong valve and it doesn’t seat properly in the rim and I’m still left with a leak! And I’ll possibly have to buy a box of 10 rather than just 1.

In summary, from reading this thread I believe I need a steel valve that’s rated up to 5.5bar or 6bar and that’s suitable for an alloy rim pictured below (which I believe simply means it needs a plastic or nylon washer to prevent the reaction of dissimilar metals). I don’t need a sensor valve for TPMS (I have aftermarket Tyrepal sensors). I understand the rim hole is 11.5mm diameter but are valves a standard length?

Can anyone recommend a valve supplier, or indeed any other advice? I really thought this would be straightforward but like most things to do with motorhomes, it isn’t!

You need TR600 for 5.5bar max or TR600HP for 6.9bar max.

Thanks everyone, as ever the forum helped me to resolve the issue.

I followed Casion’s recommendation for Auto4, a specialist tyre supplies business. They were very helpful and I purchased 3 different valves to make sure I got the correct one. At around £2 per valve it was worth hedging my bets.

I took the valves to my local ATS and once they removed the old valve it was clear that the version indicated in the picture below was the correct one. I’m no longer losing air so hopefully it’s solved the problem.

When I get back from our current trip to Scandinavia I’ll make a new post on tyre valves so it can be found more easily by the search function.

Thanks again.
