Leak at base of rubber tyre valve - DIY Fix?

[ukkid35]

Do I have any hope of replacing the valve myself?

The tyre is an AD08RS with pretty stiff sidewalls on a 15" rim

I have a cheap Workzone 2.5 HP Air Compressor from Aldi

May as well just take it to a local tyre place. It’ll take them seconds to the replace the valve rather than you wrestling the tyre trying to break the bead without proper tools.

I wouldn't recommend it. There are no upsides, and a world of pain taking a modern tyre off a rim.

You can only change the valve with access to the outside of the rim.

Well I don’t think I have ever seen ad08s on a smart car before :-)

A mate of mine put AD08 on his Integra some time ago and I decided to copy him

He even lent me the car a few years ago



I have fitted AD08R to my other cars as well





I did once get it wrong on an out lap when they were cold

Then last year I nearly killed my 928 as it was getting damp and I was on the wrong line

But that was definitely user error, I am a big fan of the AD08

What's wrong with the valve ?

I'm sure it is possible to change it DIY....but I would imagine it is like trying to take your pants off over your head without the correct tools

I used engine lube around the base, and then used a valve extension to spin the valve free, and eventually push it in towards the centre

Then I was able to spin it to try to clean up the mating areas, and pull it back through, and pressure the tyre

After two or three goes the bubbles seemed to stop coming through the engine lube

However, it will be a few days before I can be sure it's really fixed the leak

I thought someone had mentioned this ages ago on here...there are tools for this

Although I do prefer short valves as opposed to the regular long valves.

Steel wheels only. The depth of the hole in alloy wheels means forcing a valve in from the front without buggering up either the valve or the rim is nigh on impossible.

Thanks was tempted, but the Sealey description only mentions Steel wheels as you said

No pressure loss after a week so my zero cost fix worked nicely
