The front right hand tyre on my mk3 golf appears to lose pressure much quicker than the other three. Normally needs to be adjusting on a weekly basis, which I appreciate maybe the norm, but losing 50% on one tyre ? Not sure if its a puncture as deterioration is not immediate. Could it be linked to the steering ? I'm due to have the care serviced in a couple of months time so would you have any thoughts ? Cheers
