Was a Clio 1.8 16v
When i had my old phase 2 wheels on, one front one seemed to fall down to 25psi every week whereas the other front tyre maintained 35psi. Theres no offending object and their new tyres on front. The same happens with the rears.
Just bad tyres? Or wheels have erroded and no longer has a perfect air tight fit to the rim? If this is the case does re-fubbing them sort out the seal edges?
