A539's 195/50/15's on rover 216

I'm running around 27 psi in the tintop, which I think is too low. Looking at the scrub on the tyre i don't think i am using the centre much.

What are other people running, is 30 more like it??

Well I have a slow puncture on the NSR of my Golf and it wears A539sin that size , so my pressures are 28 - 28 - 28 - 73...
