Depends on a few things matey, How hot the weather is ,how hard your pushing and what tires your using and if your using tire warmers,,,if its a full day sesh just go out with the road pressures and once warm check the pressures you should notice theve went up just drop a couple of psi each end aand see how it feels but don't get too caught up in the pressures m8 just go out and enjoy,if your quite a quick rider maybe drop them to 30 cold and see where you go from there... i usually run 30 psi front and back hot on metzeler racetecs so again on road tires youll want a bit more in them , Enjoy
