Confusion ignorance High pressure tyre valves

I need my first set of replacement tyres for my 5 year old Broadway. I have metal valves on alloy wheels. I have looked online at all the usual tyre dealers/fitters. I then contacted several to make sure of two things

1 They could actually fit my vehicle in (size wise)
2 They would fit/replace the high pressure tyre valves

I have been met with a wall of ignorance and confusion. One fitter told me I didn't need them, several remained silent for several seconds before asking if I had rubber or metal ones and they didn't have them in stock anyway. Others stated they simply replace the inner valve not the stem as it is metal. Others stated they had to order them in specially and I would have to pay for them as they were not 'standard' valves. 
With the number of motorhomes on the road I would have thought they would have changed a few tyres by now and know what they were doing. 
What I would like to know is can I simply have the inserts changed, do I need totally new valves, has anyone else successfully had new tyres fitted?
Where did you go?

With normal steel wheels it is well worth having the metal valves fitted, but I think you are wise to query what can be fitted to alloy wheels to avoid problems with different metals that can be an issue in the case with aluminium.
Sorry cant be of any help.

Why change the valves, on the Autotrail I had with metal valves I never changed them in 12 years of ownership ,rubber valve I can understand changing as uv deteriorating the rubber

The valve insert was changed as this was removed to deflate the tyre and a new one inserted to inflate

I think it is usual to only replace the valve insert on metal valves, certainly that was done when I replaced my tyres last year on alloy wheels.

I always replaced the metal valves which I supplied, only a couple of pounds each,, but asked the fitter for approval before fitting. They were on steel wheels

Do you make that many miles, that you have to replace the tyres after 5 years.
In Europe up to 10 years of use , and then preventive replacement, is normal, if you make little miles.

If you have external sensors for TMPS,  the TR600 series is most likely OK , because they are made for 95 psi cold pressure, and wont bend under centrifugal forces at higher speed, so wont leak then at the hole in the rimm.
Metal valves certainly no bending.
The TR600 is snapp in valve with about same price as normal rubber TR4?? Series, so can be renewed every tyrechange.
Metal valves, only the rubber rings have to be renewed, but is seldom done, so in practice can be unsaver then the TR600.
And if you dont have sensors, bending wont happen.

My Nuevo is 2008 Reg and I have just had a metal valve changed as its seal was leaking against the alloy rim.
I didn't change tyres at 5 years, was advised to, and did, check the tread, walls etc annually with no problems.
I think I made an executive decision to change applicable tyres at 10 years tyre age although they seemed to be OK.
Normal wear, especially on fronts, may overtake this process.

I had to have a tyre replaced on my Devon (Mercedes)by Kwik-Fit. I had to go back repeatedly due to the tyre going down slowly. After many conversations they finally agreed to fit high pressure valves. To my surprise they replaced them on all four wheels. Even a large company like Kwik-Fit are not knowledgeable on high pressure valves. Also if you buy them on line beware there are different lengths. I have alloy wheels and they got the wrong size and had to reorder.

For information, I've copied the valve specifications form the Continental Data Book below:

*)43 GS 11.5 are snap-in valves approved for up to 4.5 bar.
38 G 11.5 is a valve for the hose.
Standard rubber valves are only approved for up to 4.5 bar in service.
TR 600 XHP and TR 602 HP (ETRTO V3.23.1+2) are reinforced snap-in valves approved for up to 5.5 bar. 40 MS (ETRTO V2.04.1, V2.05.1) are metal valves approved for pressures up to 6 bar and higher.

The CP tyres recommend TR600 XHP, TR602HP or 40 MS valves.

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!

Try auto4

I think I would explore all the local tyre fitter options first before buying a valve and then asking them to fit it.  If they can source CP tyres they must be able to source the right valves for them.  There should be lots of experience of this from Forum members who have had CP tyres fitted to their alloy rims with or without TPMS sensors.

I replaced mine last year when I put on new tyres. I looked at the TR600/602 as specified in the Continental datebook, but decided to replace the metal stems like-for-like (the threads were a bit abused by a previous owner / garage).

My tyres were fitted by ATS - they did not have the valves in stock so they ordered them from Rema Tip-Top in Leeds. I've attached photos of a spare I kept with the model numbers on, and a screenshot from the Rema Catalogue. These are the TPMS type.....

Hope this us useful.......

On aircraft we would just replace the Schrader inserts and they were 180psi.

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.

A while back when we had a Duetto and after an all rubber valve had been blown out caused by me only sightly over inflating the tyre, broken down and us needing our Transit to be recovered by the AA, I later bought some metal sleeved rubber valves. Our local Kwik Fit dealer wasn't very knowledgeable but they were happy enough to fit the valves I supplied. Our Duetto had steel wheels, now having a Kemerton XL with alloys I'd be wanting all metal valves fitted.

I've looked carefully at the comments in this thread since I am likely to replace my Broadway tyres this year; they are still the original tyres.
My excellent local garage does fit tyres so I want to be able to ask him to source everything required. I will want like for like replacement tyres if possible (Continental Vanco CP)  but I am still not sure what to ask for on valves, etc.
From what I have read here, I should be asking for high pressure valves with the requisite Peugeot Boxer tpms system, suitable for pressures up to 5.5bar?

I replaced my original 4 road tyres last year as they were 7 years old. As far as I know, my local, trusted tyre dealer kept the original metal TPS valves.

By the way, I also intended to replace the Continental VancoCamper CP tyres like for like, but shortly before I took action Caraman drew my attention to new tyres just then introduced by Continental, called VanContact Camper CP. They are M&S rated. As far as I can tell (after 3K miles) any handling or noise difference from the VancoCampers is imperceptible on roads; I've yet to test them on wet grass / snow etc. I've no regrets about buying them.

Thanks for the information, Cymro.  It's useful to know that your tyre dealer kept the original monitoring valves.

I've just had the van's tyres changed.. Same again..Continental Vanco CP.
I was expecting to have to drive for 20 minutes or so to eliminate the TPMS warning signal but nothing appeared!. I was surprised since various posts suggested that you had to drive a certain distance with new tyres or if the pressures had been changed.
The warning light does show up with all the others on the dash when the ignition is switched on and then goes out when the engine is started as it should.

Ah. I hadn't thought about the warning light and the possible need to reset. I'm certain that I simply drove home (2 miles) from the tyre fitter on the new tyres without any warning from TPS - just like you, Merv.
