I know bike tires will lose pressure in colder seasons because the air temp causes the pressure to drop, but is the inverse true? Does bike tire pressure go up in summer due to heat?
If so, do I need to deflate the tires a bit in summer? Do bike tires ever explode because of a temperature change?
Pressure, volume and temperature are all interrelated.
Assuming constant volume; as temperature goes up, so does pressure to compensate. (Alternatively volume can also increase. While tire generally don’t expand much, they do expand slightly, since rubber is… well, rubber.)
