Tires lose pressure quick?

[RR76]

Car is 10 years old and tires lose pressure pretty quickly like in a few days they can go from say 38psi to 26psi well the worst can, the other may drop from 38 to 32psi at a rough estimate.

I assume it's the wheel rims causing this, rust etc. Is it worth taking them to a tire shop, can they do anything about it or would you need to buy new wheels?

Yes, it's worth taking to a tyre shop. It could be the wheels, or it might be a slow punture, or a leaking valve.

How old are the tyres?

Take it to a tyre place and let them have a look. Could well be corrosion on the inner edge of the wheel rim, if it is then they should be able to rub it back and seal it. Saying that reminded me that I had a slow leak on the spare tyre on my van, when the tyre was removed it exposed a rim which was so corroded the tyre place couldn’t fix it so had to have the alloy refurbished.

If you really fancy giving it a go yourself, take the worst wheel and tyre off the car, pump it up to the maximum safe pressure, and then with it laying flat, put a mix of a little Fairy liquid in water around the rim and some on the valve (cap off), and keep an eye out for bubbles forming. Bubbles from where the leak is. Flip the wheel and tyre over, and do the same again.
