I read few pages and it seems that everyone is running quite high pressure as oppose to what's recommended in the manual.

I have Astra H CDX on 205 55 R16 and recommended pressure is 27.5! Got new tyres few months ago and they pumped it up to 36 but that was quite uncomortable so I took it down to 31.

Isn't higher pressure making the tyres wear out quickly as well as shock absorbers and loosing bit of control?
