Fuel efficiency on my bike is good enough for the girls I go out with lol
That is quite unnecessary. For one thing, mfgs have taken that into account and that is why they recommend only checking pressure on cold, undriven-on tires AND THEN they say DO NOT bleed tire pressure down if you check them hot!

For another thing, burst pressure is up around 200 psi so no, if sidewall max is 41 and it goes to 46, it won't blow up.
