Thanks for your replies/answers. Seems everyone runs on different pressures! What difference does 3-4 psi make though....is it a safety issue? Been running on 31/32 psi for 3 years without any trouble- tho' did notice steering improved now tyres at 36psi....guess that's because there may be slightly less rubber/tread on the road surface.

Still confused!

(Thanks Mo, but I've lost the sticker with the tyre info on from the door pillar]
