I have had Hankook Ventus V12 EVO tyres on my FR TDi for about three years. Shortly after having them fitted I noticed that they were losing a bit of pressure (about 2 psi per week.) I went back to the fitter but they said that it was too small a leak for them to find in a water bath. They offered to refit them for £13 per tyre but I decided not to bother.
About three months ago I replaced two tyres with V12s again and hoped that they would be all right. However, they are still losing pressure. The first time I checked them, after about a month, two of them were down by about 7 psi and the others by 14-15 psi. I checked them again last night after a fortnight and the fronts were down by 2.5 psi and the backs (the new ones) by 6.5 psi.
Obviously something is not right but I have no idea what is wrong. Possibly the rims are corroded and air is escaping under the paint or I have faulty valves fitted. Does anyone else have this problem or any suggestions as to what is causing it?
