I drive a Euro C180 1994 model and today it felt quite hard like the tyres are over pumped. Before the last service, I had it very low like 28psi and the ride was very soft and smooth. At the service I was told it required 36psi which I thought was far too high. What do you guys think, is 30psi just right? The car is only 1350kg kerb weight and thats quite light compared with my Camry which is 1830kg with a 2.2ltr engine compared with the 1799cc of the C180. Tyres are 195 standard 15inch steel rims.
