Tires related question

[invisible]

I have one tires related question. Tires are Nokian APT A/T, 255/20/R50. 2.5 years old and less than 8K miles on them.

After returning from trip (car was sitting under roof for 30 days) I discovered that rear right tire was half way depleted. The car was parked during this time on flat surface. I did inflated it but the problem returned several days later.

I moved it back where it was parked before - on the inclined driveway (car facing downwards) and I see that rear right is not as depleted after 3-5 days as before but now the front left got depleted half way.

Moved car to flat surface again, left from last Saturday when I inflated every tire to 34 PSI and today discovered lower right almost completely depleted and front left pressure dropped to 20 PSI. Other two are fine.

So... what causes this and how can one fix it?

I took first at Tire Rack but they refused even to look at them telling that side thread on rear tires are worn and telling me that this is because wheel alignment and the only way to fixt is - to buy new tires (from them).

Then I took it at another shop, they took $100 and tell me that nothing is wrong with tires or wheels.

So... what to do? I am not willing to running from place to place or spend another $1400 on new tires.

Everything was fine for 2.5 years

Go to a tire shop with a dunk tank.
Could be a valve stem leaking.

Well - no on that part - Les Schwab and Tire rack simply refused even to remove tire due to a single tire. I told them that I would pay - they refused. And the local mexican shop took $100 and told me there 'everything is fine'.

Fortunately there is a guy in our neighborhood, who has own shop and agreed to take a look.

Moral of the story - having your own mechanic is as crucial as having a good doctor.

Or you can become mechanic on your own which LR successfully does with their customers since 1947.
