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?

    You are overthinking it my man. Yes, the pressure does go up, but overinflated tires need to be way way way over inflated to explode. Unless you are a pro cyclist or store your bike in the trunk of your Kar in the Sahara desert… no, they don’t pressurize enough to matter.

      Overpressure can cause its own issues, it can cause uneven wear. That uneven wear can lead to bald spot that can cause the tire to blow.

      Optimal tire pressure should be maintained at all times, not overthinking at all.

      To do the math, an assuming constant volume, a 30C increase corresponds to around 10% increase in pressure. That’s well within the margins of the tyre even if you go to the max rated.

      If you then consider deformation and most importantly leakage over several weeks, this is a non-issue.
