You won't see anything like +/-5 psi difference between hot and cold in your bike tires. You can't compare the operating parameters of the tires on your bike to the ones on your car, it's totally different. There's no way you can put anything like the energy and loads through your bike tires that your car tires have to deal with. you can top up your bike tires any time, even after the hardest ride of your life and it won't make a practical difference to when they're cold.
