Tyres Need Replacing, Steel or Rubber valves?

[Lenny HB]

The snap-in ones I linked to don't have the collar length problem.

I can't see any links in your posts.

Sorry - wrong word! - not a link, the ones I showed in my earlier post, as below. The picture is from the Schrader catalogue.

I can source genuine Schrader snap-in valves, special high pressure, nickel-plated brass core ones, that are rated to 14 bar - which is 167 PSI - cold pressure. These have the advantage that they are quick & easy for your local tyre place to fit, they are what they are used to. Snap-in valves are also reportedly much more tolerant of the inside of the hole in the rim not being perfect, compared to metal valves. Rims can corrode on the inside over time.

Which ever you use never use metal dust caps. They bond to the threads and are pain to remove. I bought a work truck recently and had to have all four wheels and tyres removed and new valves fitted

I second this! I put some metal dust caps on a car and 3 months later they were seized solid - I had to very carefully cut them off, a right faff. Plastic dust caps only now!

So i found the original valve that leaked last year and then compared it to the replacements that i have (only have 3 of them though), see pics. The replacement looks to be just slightly shorter but not by much and not i would of thoughts something i need to worry about. Thoughts?

It's the collar length that could be a problem Zac - if you've got alloy wheels.

By that I mean the length of this bit:-

The valve is put through the hole from inside the wheel, obviously, but then the collar is screwed on from the outside. The hole in the outside of alloys is recessed - if yours is too recessed, those new ones won't fit. It depends on your wheels.

Steel wheels wouldn't be a problem. You can get valves with longer collars like your old ones - or hang fire and see if I can get these snap-in valves.

that bit unscrews and i am assuming pulls the valve in (i think), the new one also unscrews but it's not as long as the original thats for sure

OK just took a pic of a tyre thats i know i had the valve replaced a couple of years ago due to a leaky valve and i think its the same one i posted which is probably why i only have 3 left. Can't be 100% sure but this is the valve and it looks very similar.

That's exactly what the collar does - pulls the valve body tight against the inside of the wheel.

Your wheel picture - I can't be 100% but it does look to me like you've got a style of wheel where the short collar type you've already got would fit. You could get long collar anyway, to be on the safe side. I'm not recommending these ones as they are unbranded cheapies with no published pressure rating, but this sort is what I mean:-

Or - hang fire and see if I can get the Schrader pull ins in time for you - explicitly rated to over 160psi, no collar to worry about, a named manufacturer and reputedly more reliable than metal valves, as Micheldever said to you. But - more expensive and there may be a wait. If you're keen let me know and I'll chase them later today if I don't get a reply to my email.

 

[Feltwell]

By the way, do you see why the collar length matters now? The red bit below - on some styles of alloy the valve hole is much more recessed than yours, the hexagonal part of the collar would hit the wheel or you wouldn't have enough room to get a socket on it. Even on yours, you'd have to be careful doing them up not to mark the alloy with the spanner or socket. Better to use long collar and do them up with a socket, you can keep it well away from the alloy then.

 

[zac]

Yes it does look very tight, the ironic thing is that micheldever fitted that metal valve that i gave them with no issues. I do have a bit of time to spare with these valves as my motorhome is being picked up today to have some work completed which will likely be at least a couple of weeks but i do need to get this sorted so i can get the 7 tyres moved from my garage.

With a leaky metal valve it's often not the valve but it has worked slightly loose, I had one with a very slow leak the valve just needed tightening and you can do it from the outside with a lot of them.

interesting, i will try that next time for sure.

Will these work although a little expensive if you need like i do 7? Link Here

Yep, they are the ones I was proposing. Not cheap but the best quality, and your tyre fitter will like you!

I've had nothing back from the importer yet so if you want to go ahead and buy from there it would probably be quicker.

i still do have some time as the Motorhome has gone back to the dealer today and thats going to be at least a week if not longer, which length were you looking at as there are 3 to choose from.

The 40mm ones are the most common I believe, so I'd go for those. That's actually the only site I've seen that even offers the other 2 sizes!

they do seem to be quite rare, thanks anyway

I'll have the genuine Schrader valves in stock tomorrow Zac - will drop you a note with details.

sorry, just ordered this morning i ordered 10 which came to £43.14 inc del

 

[Feltwell]

Ahh well - I could have done you a little cheaper but never mind! The importer was slow in responding, person concerned has been away.
