Thread: Tire Pressure - 30psi required? WTF?

Nitrogen is not going in my tires if I have to release some of the pressure twice a year to reset the TPMS when switching summer/winter sets.

nitrogen seems to not be affected by the cold or heat as much and just air. nitrogen molecules are larger then air molecules the tires should remain in a good ball park going into winter.
