@2davidc8 – That was the conclusion I had drawn, as well; however, I reasoned it out like this: tread patterns are made to go in a particular direction and tire manufacturers aren’t likely to make different tires for the left and right side of your car. Therefore, my theory is that the tires on one side should have the full print of information on the sidewall and the tires on the other side should have that minimal information. The only thing that would throw a wrench into my theory is if interior sidewalls are reinforced differently than the exterior, but most tire diagrams I’ve seen seem symmetrical.
Most of the time, the tread pattern is pretty clear in indicating the direction it should face. The Tire Rack site might also show you the tread pattern if you know your make and model, so you could double-check that as a reference. This is why they say to rotate tires between front and back on the same side of the vehicle. I’ve always wondered about my full-size spare, though. What if it’s mounted on the rim for one side of the car, but I get a flat on the opposite side?
