The Limos.com Forum Has Moved!!!

Has any one on the form changed form regural air in their tires to nitrogen. We are considering it. Would like some input on the subject.

Thanks for all of the comments. I knew this would be the place to ask about it. I guess we will keep regular air in our tires.

When I raced karts we could see a huge difference. The heat built into a tire 11 inches in diameter at 65 MPH really notices nitro. We would check the tire diameter right before the race and again after and with regular air the tire would be quite larger when hot, but with nitro it would keep it's size better than 50%. Tire diameter in a single-speed kart has everything to do with gear ratios and can make a big difference in your lap times when the tire heats up. Chemicals were used on the tires to make them heat-up faster and "come in", but that's a different story. Controlling your tires on the track is a science that few have mastered.

For a car on a highway, not enough heat is built into the tire for nitro to make any noticeable difference, therefore I don't buy into the nitro in car tire idea.

In racing, YES, in street cars, NO.

Big hassle and expense with minimal return.

If I had a very valuable classic car with original, or obscenely expensive wheels and tires, maybe....

Most of us don’t keep cars long enough to see any benefits or gains in longevity of equipment due to using pure nitrogen instead of air.

I still prefer to use regular air. The tire check machine at our shop uses regular air.

I wonder if nitrogen and regular air can be mixed. I mean if the nitrogen in the tire is low can you mix regular air or do you have to use nitrogen. A question to ask my tire guy.

Some "Straight Dope" on nitrogen I found:

I pretty much agree.
