   30 psi is way too low. You're wasting fuel and wearing through the tyres at an unnecessary rate.
   
   36 psi front
   32 psi rear

   It can't be 36 psi front and back as the weight distribution is biased forward. It's the contact patch that's important, if the pressure is too high (or the weight too low) the contact patch is reduced (leads to central wear and less road grip), if the pressure is too low (or the weight too high) you get wear on the shoulders, less performance and increased fuel consumption.
   
   It's 36 psi Front
   32 psi Rear.

    Says in the manual 36 front 32 rear, I wasn't sure so had a gander, it was the PSI for the tyres I have, was for Michelin or something, but can't be much difference. Anyways when I plugged the air, it was at 26 PSI lol, l. I was getting like 31mpg on this . Didn't do the rears though, some guy was waiting for ages whilst I read my manual etc. lol
