I think I mentioned this earlier as well, but I did not get an answer.


I have a 2012 Toyota Corolla and I got brand new tyres for it 8 months ago.

However, from the start, I would always get a low air pressure in them and had to pump in more air at least once a month.

Is this normal? The place where I live has very very bad roads, can that have caused this?


The problem here is that the rim may not have been cleaned properly when it was installed. Which causes the tire to loose air where it makes contact with the rim. Have had this happened to me before.

Take the car to a tire shop and have them remove the tire. Clean the edges of the rim where the tire makes contact. Reinstall and balance the tire.

Make sure they test it for leaks.

Also one other thing that comes to mind is that the valve steam may be leaking.

So maybe have them check for leaks first then go on with the repair.

Very Interesting. I never thought it could be a problem with the rim.


You are correct about the valves. I once had faulty valves and had to get them changed. Maybe I should look at the valves first and then see if it solves the problems. Btw, can new tyres have faulty valves?
