Water in tyre...

[chris1001]

Had a couple of new tyres fitted to my L200 today, the new tyres had been sitting outside of the garage in the rain, and due to them being fairly tall sidewalls they trapped a fair amount of rain, one of the mechanics made a half hearted attempt to knock the water out and failed, proceeded to mount the tyres. I asked him if this was OK, as they were so wet, and would it corrode the alloy or damage the valve, he said its totally fine....

So wondering what other peoples opinion is on this? The truck doesn't have TPS valves - but will be doing some serious mileage in 30+ degrees C very soon.

Once in there, it's hard to imagine it doing anything but stay in there. I doubt it would do any harm, but it would be interesting after a few thousand miles to see if it is still there.

Let's face it, it can't escape, it can't evaporate etc.

It is difficult to get water out of a tyre without actually mopping it up etc

I know someone who struggled to find a noise for months on his car and it ended up being a little marble that had formed from water collecting the dust, or powder from the inside of the tyre.

A sort of pneumatic gall stone!

hmmm.. I have a cunning plan, wait until the tyre is as hot as it can be after a few hours at 70mph and then dump the air, if it comes out as steam then great I've lost some water... could be a slow process. If it comes out as dry air then I guess I have nothing to worry about.

I think the laziest way is basically what you've said, but jack the car up to avoid damage to the tyre, and remove the valve core to maximise airflow.

Personally I would get it removed. The valve itself could corrode, also the water may not evenly distribute itself when moving and cause vibration.

Tyre valves are pretty much all chrome plated brass, so they won't corrode, but I would still insist on removing it & properly drying the tyre.

Water when heated enough turns to steam, steam is 1600 times the volume of the water from whence it came.

Cannot imagine what that would do to the tyre/car if that came to pass, whether likely or not due to the pressure in the tyre.

They would take ages to disperse. I remember when I was a tyres fitter removing tyres that had water in them when onto the rim. All it did was corrode the inside of the wheel rim. They generally have moisture inside them one of the advantages if you fill a tyre with nitrogen, that prevents moisture.
If that water does not evaporate with heat, it would get between the beads and cause corrosion and eventually let air leak past the beads.

I really cannot see why the person who fitted the tyre to them rim did not just use a sponge to soak up most of the water, then dry the inside with an old rag or cloth. It is so simple.

If you don't want to go back to the tyre shop, best bet is to inflate the tyres to around 40psi, remove the bore pin (if you have the tool) let the air out completely, then reinflate, you would get most of it out if you do that twice.

Filling a tyre with Nitrogen doesn't prevent moisture when it is already in the tyre.

If the water evaporates, where do you think it will go in a sealed tyre?

If air can't leak out (which it shouldn't) what makes you think water will?

I would say the same...but must admit, I'd love to see it driven for a few thousand miles then taken off to see if it is still in there ! ( which it should be....but you never know )

My opinion? You don't care how you store tyres. The fitter you chose doesn't care about doing their job right! Careless on both counts An airline would blow out most of the water, and a wad of blue paper roll would get out the rest.

Why is water in the tyre important?
A/ it makes balancing the wheel impossible
B/ It makes setting the pressure impossible. As the tyre heats up, water will evaporate and increase the pressure far more than dry air.

Take the wheels to a proper tyre fitter and get it done properly!

Why claim that I don't care how I store tyres? I wasn't storing the tyres, the garage was.....

Just done 2000 miles of motorway driving, no issues so far, managed to get a bit of steam out but not much, will get them removed and dried properly when back in UK.
