With the non-stop heat we’ve been living with in Los Angeles this September, I’d like to remind everyone to check their tire pressure. Hot weather means that air escapes from bicycle tires faster than it normally would. However, don’t over inflate your tires! All that extra heat combined with too much air in the tire can spell trouble: blow-outs on hot days are not uncommon (a loud boom and a popped inner tube).
Why do bicycle tires lose air anyway?
