I'm sure this question has been asked and answered before but... When checking tire pressures I am aware that you should check them when cold, meaning before they are driven and after they have had a few hours to cool off after driving. But what about the difference between checking them on a day when it is 90 degrees (F) and one when the temperature is below freezing . The pressure will drop as the temperature drops so my thought is that one should check and adjust the pressure to have optimum performance, routinely checking as the seasons change. I don't remember doing this in the past but I could have just been being sloppy.

Tire Pressure Question
- Thread starter Beasts
- Start date
Once you determined the cold pressure needed for the speed and load on tyres, with maximum reserve at wich comfort and gripp is still acceptable, you can let the cold pressure flow with ambiënt temperature.
At least that is the conclusion of this pigheaded Dutch selfdeclared tyrepressure specialist. It will be proven right in about 20 years.
The general idea is to fill if determined 35 psi, that at 30 degr F and 100 degr F.
Tire pressure is to give tire a deflection that wont overheat tire-material when driving the speed constantly, for wich its determined.
When hot outside the tire needs the higher pressure to give lesser deflection, so lesser heatproduction at same speed. Cooling down is also lesser then, because of lesser temperature differences between tire material and in and outside tire air.
When cold outside, the other way around, but then highening up the pressure is allowed for energysaving and riding quality.
I made pressure axleloadcapacity lists in other topic, to determine the cold pressure at about 20 degr C/ 68 degr F.
Here the topic, I gave several P:LC lists.

I adjust tire pressure several times per year according to the season.
When winter comes, I wait for a cold morning with temperatures few degrees below freezing point and adjust tire pressure.
When spring comes, I adjust in the morning when temperatures are between 5 to 10 deg C.
When hot summer is on the horizon I adjust the pressure when morning temperatures rise somewhere in the region of 15 to 20 deg C.
