Costco uses Nitrogen in tires. It is free if you bought you tires from there. According to the pamphlet they gave, it is drier compare to air, so in hot weather inside of the tires doesn't get worn out as much or as easily.Top Dog said:Has anyone heard about putting nitrogen in their tires? My next door neighbor Owns 3 tire stores and he swears by Nitrogen.
It is an Inert Gas (noncombustable) that NASCAR and other Racers have used for years. Technology has just caught up to a reasonable
way for local Tire Stores to use it.
1. Tire holds pressure for up to 10 Mos or more ( unless you have a flat) and is not affected by heat, cold or altitude changes.
2. Reduces heat build up at highway speeds.
3. Is noncorrosive to Aluminum Rims
My Dealer Charges $19.99 + Tax for up to 18" rims and $22.95 + Tax for up t0 20" Rims. That is "EACH" Tire
I will have him put it in my tires when I finally receive my Enclave. we are planning on a long trip this summer and will see how it works out
They highly recommend to bring in the car any time you put regular air in the tires due to slow leak or flat, so they can release all air and refill the tire with Nitrogen, again the service is free when you purchase your tires from them.
