Tire pressure increase

Remarkable improvement in steering feel was observed on my TOYOTA Caldina AZT241W after  increasing the tire pressure according to the climate temperature change, now we have some adjacent point from Summer to Autumn.
About 10 degree Celsius lowering phenomena happens now in Japan, leading to tire pressure reduction about 0.3 KP. So, I make it a rule to increase tire pressure as a routine periodical maintenance.
Tire pressure has much to do with the the balance between the axle constructive design including the spring rate and the dumper setting by the original design.
The tire selection and it's pressure setting are not defined unreasonably by the research and developing division of the vehicle manufacturers.
This is why I am relatively nervous on the tire pressure setting on the vehicle.
