That jives too with as many tires that we repair each week. The most common in order of repairs is the right rear, the right front, the left rear, the left front.
My theory on this is:
The right side tires are near the shoulders of the road, where everything (trash, nails, etc) eventually gets pushed over to, either by vehicles or water. The front right tire can kick it up where the back right tire gets punctured.
The front right tire is next, as it may just hit the object directly first, and gets punctured.
Now, the left rear tire is next in frequency because the same applies as the front tire kicks it up and the back tire gets punctured.
Then that leaves the front left tire, which is the one we repair the least
The best (or worse depending on your point of view) thing to cause tire punctures is heavy rains (which washes all kind of stuff onto the roads) and street sweepers (that also pull things off the shoulders into the roads that don't get vacuumed up). I have actually watched street sweepers throw stuff over into other lanes in roadways.
