Answer: The tire pressure will be higher when the temperature is higher.

Pressure is the result of collisions of gas molecules with the walls of the tire.

Temperature is a measure of the average kinetic energy of the gas molecules.

As temperature increases, gas molecules move more quickly and they collide with the tire walls more frequently and with more force.

Pressure and temperature are directly proportional.
