Assuming you have E-range tires, 45 cold is low. Check the sticker on your doorsill. Those cold pressures listed are just that. Don't try to guess what they might reach warm. All you'll do is increase tread wear and lower gas mileage. No need to get tricky with air pressure. You'll notice that when you raise cold pressures to the recommended levels, that they will gain less heat and pressure warm than they did when you started out where you are now. Tires don't mind pressure as much as heat. Temperature/pressure-related blowouts are caused by low cold pressures, not high cold pressures. The heat gain on an underinflated tire is tremendous. Been there!
