The weather plays a big part on the air pressure in your tires. Hot weather may make your tires over inflate, but cold weather may cause your tires to be dangerously under inflated.

Many newer cars have a tire pressure monitor built in for each wheel that constantly measures the inflation of that tire. Most TMPS systems measure your tires when they become significantly under inflated, and not over inflated.

Nitrogen tires prevent this. Why?
First is that nitrogen is less likely to migrate through the rubber than oxygen, which means that your tire pressures will remain more stable over the long term. Racers figured that out pretty quickly that tires filled with nitrogen rather air also exhibit less pressure change with temperature swings. This leads to better gas mileage and longer tire life.
