Everything about the SR 71 was important and thought out when a problem occurred, and Lockheed provided the answer. SR 71 tires …Workers used aluminum on the areas where the wheels retracted and added latex. Then they filled the tires with nitrogen.
The tire pressure was 415 pounds per square inch compared to the 35 psi in your car. With all the high speed that SR-71 Blackbird would fly, it caused the tires of the aircraft to also get heated up immensely just like its airframe, despite the tires being housed inside a cell. If these tires were inflated with normal oxygen, then it would have seeped out of them even while the landing gear was being retracted.
Tires made by BF Goodrich
I have over 700 flight hours in the A-12 and the SR-71 and never had a tire blow out. There are three tires on each side. We used brake coolers after landings because of the heat generated during flight and landing. The tires were normally changed after 10 takeoffs, because the wear & tear & heat is during the time of rotation with a full fuel load. When we could we took off with half fuel load and air-air refueled shortly after takeoff. That reduced the takeoff weight by about 40,000 pounds. The fully loaded SR-71 weighed about 160,000 pounds. I don’t believe that we had a tire problem. Quoted by Colonel Ken Collins, A- 12 and SR -71 pilot.

Something is fishy about that narrative above. It implies that tires are typically inflated with oxygen? Who in the world would do that? “Air” is mostly nitrogen with only a small percentage of oxygen, so air is mostly nitrogen already. And, why would oxygen (atomic number of 8) seep out easier than nitrogen with an atomic number of 7? I thought the main reason for nitrogen fill was to control for water vapor content.

Mike, I suspect it was a slip of the tongue. Probably meant to say normal air, ( which, as you pointed out contains moisture). The most important thing would be controlling the pressure variance through the temperature range.
Remember, the guy was only a pilot. :D

I've never heard any of her music before.

I'd ride the Duc back and forth on that road until someone called a cop.

There is a road in California coming out of Sacramento, out into the desert, going towards Las Vegas that is that hilly or more. No trees as I remember. In my 911 fully loaded with two weeks of clothes for my wife and myself, and my wife on board, we came to that stretch of road. Driving just the speed limit, I swear we almost got air a few times, and I know the suspension was at full compression at the bottom of the hills. It was a bizarre road, and kinds fun and almost scary. I just know we left Sacramento, and got to Vegas the evening with no interstates as far as a road location.
