Nope. All gases, regardless of molecular composition, behave according to pv=nrt (pressure*volume=number of moles * constant * temperature.) It is IMPOSSIBLE to have constant pressure under rising temperature without changing one of the other factors at the same time. Since the inside of a tire is a roughly constant volume, unless you are planning on leaking gas when the temp goes up the pressure WILL increase.
