I've been having some issues with my tire pressure that I never had with tires on my other bikes. I'm not sure if it has to do with the crazy weather here in the Bay Area lately - temp fluctuations from 111°f (day) down to 57°f (night). While those are extreme situations, I'm wondering if that in conjunction with the weird high/low pressure systems that have been moving through would cause me to lose anywhere from 3-5psi on a weekly basis in both tires. It's more noticeable on the front end because it gets all squirrely when it gets below 35psi. I like to ride with firmer tires (38f40r). Is the frequency I'm having to refill my tires something I should be worried about? Possible leak or natural pressure loss due to temps/breaking/general use? Bike is brand new (2.2k miles) and no visible issues with either tire. Thanks in advance for the recs!
