I'm an owner of a GP 1.4 16v Sport, and i would like to know if anyone knows anything about the tire pressure that i'm supposed to have. The manual says 32psi rear 34psi front(for 1.3 mj version-for petrol it doesn't say). Others tell me that all the tyres should be at 30 psi. Others tell me that because of the 17'' alloys the pressure for all tyres should be around 32psi. Anyone has any suggestions?
