for example, the mavic open pro listed this as their max pressure;
19c tyres - 146psi.
28c tyres - 117psi.
therefore Gatorskin and 4 season 25c at 110psi, althought I personally find it idea for the rear tyres to be pump up a bit more says to 120psi as it carry most of the weight.
Don't forget about rims.
