According to what I read online they say six years. After 10 years you’re risking your life. My knowledge is based on seven years of tire testing and development for Hoosier.

I agree if they have been mounted the whole time and exposed to UV radiation. Stored indoors unmounnted in a quiet cool environment will extend the life quite awhile past the normal expected life.
Just kidding about the quiet part, but that is how I would want to be stored.

There is a long, old thread about nitrogen here on the Forum. Six of one, half a dozen of the other. You can go buy a tank, but usually code requires it to be chained to the wall.

Although I’m not a fan of filling my tires with nitrogen, I will admit there is one advantage: it’s dry, zero moisture and has no oxygen. So if you want to prevent corrosion inside, say steel wheels, it might be worth considering.
Nitrogen Inflated Tyres: Advantages and Disadvantages
Nitrogen is a colourless, odourless, tasteless, and non-toxic gas that forms about 78% of the earth's atmosphere. It is a matter of discussion for most of the

I bought my set from Costco last summer. The Tire guy at Costco( Gilbert Az) call his Bridgestone distributor in Houston, to verify they where available. Had them 3 days later. Good date codes.
have Nitrogen in the tires for my CJ3 and it's use in aircraft tires. 1. high altitude freezing 2. disipates through rubber slower than oxygen. 3. No moisture so not as much rubber degradation. 4. On landings tremendous heat can build up.

The size of an N2 molecule is about 3% bigger than an O2 molecule. In terms of permeability of a rubber tire or inner tube, there's virtually no difference. And remember, air is 80% nitrogen, so whatever theoretical difference exists, practically speaking, air will not leak out any faster than pure nitrogen.
There's a more practical reason for using nitrogen in aircraft tires: The tires of high performance aircraft have inflation pressures of hundreds of PSI. A compressor that can deliver that pressure would be difficult to haul around the flight line. However, a nitrogen cylinder is filled to about 2200 PSI, so it's a good source (using a pressure regulator) to fill high pressure tires.

I'm embarrassed to ask... I have the Bridgestones but where is the year "engraved" on the tire? I looked and looked but cant find it. I may just need a new pair of glasses

Four digits, usually in a molded oval. The first two digits are the week of the year, the second two digits are the year. Sometimes the information is on the inside of the mounted tire.
