Nitrogen in my tires

Nitrogen has two advantages. A: less pressure fluctuation with temperature changes. B: the nitrogen molecule is large enough that it does not seep through the rubber. Yes, air is mostly nitrogen, bit some of those other pesky molecules in air are actually small enough to seep through. This is why tire pressure slowly drops over time.
Used it in my motorcycle tires religiously. Put it in my truck, one tire dropped 1 psi over the course of a year. It is totally worthless in a Jeep if you air down and refill on a regular basis, and don't have a regular supply of free/cheap nitrogen.
I don't use it in the jeep, but would recommend it for any full time on-road applications.

All, I gave the dealer $31 (for the year) to put nitrogen in my tires because one of my buddies told me it increased his gas mileage on the hwy by 4 mpg. Well I did'nt see 4 mpg but I did see 2 mpg plus the ride is SO much smoother its incredible. I highly recommend this mod. just my

I've worked with aircraft tires for almost 40 years. When the regs changed and required dry nitrogen for tire servicing, I could see the difference, in service, and at tire/wheel teardown. I'm talking about tires with 150 to 260 psi in them.

I don't believe any tire is made of 100% rubber.

. The radial tire replaced the simple bias tires (which made up 90% of the market only 5 years earlier) and within a few years virtually all cars were rolling on radials. Synthetic rubber did not have the strength for radials; only natural rubber could provide the required sturdiness. By 1993 natural rubber had recaptured 39% of the domestic market. Today nearly 50% of every auto tire and 100% of all aircraft tires are made of natural rubber.
