Hi, one of my front tyre deflates rather quickly(ie. When I inflate to abt 240psi the night before, it deflates to abt 130psi the next day).I am suspecting a leak but is it with the tyre, rim or valve?How can I be sure?My car is a Renault Megane Cabriolet 2001 1.6 16V. Mileage at 120000KM and tyre is 15inch. Thanks!

You need to perform a test to determine where the leak is coming from.

One way of doing it is to remove the wheel and dump it inside a tank of water and note where air bubbles are coming from to locate the source.

I do not think you are referring to 240 psi. Most tires have a maximum rating of 60 psi for passenger vehicles.
