Nitrogen filled tires

It’s a gimmick being peddled by dealerships and tire showrooms to squeeze more cash from you. Nitrogen is used in racing because it has less moisture than air. Under extreme load, it is less susceptible to pressure variations as less moisture means less expansion/contraction.

On the road, you’ll likely never experience the conditions where using nitrogen will make a difference in tire performance. Also, if you take your car in and drop $40 or however much you’ll be charged, they’ll just drain the air and replace it with nitrogen. This will hardly be a pure concentrate because there’s still moisture inside the tire from the expelled air.

Save your money.

bingo. nascar and formula one is completely different, when tires heat up they def increase in pressure, they just want a more predictable outcome. the nitrogen will still increase in pressure, just not as much. hot brakes can cause aircraft tires to explode so heat is still a factor.
