I was confused first time when I got my RE050A Pole Position about the thread pattern.
But just like PS2, when you look at the tire side walls, you'll see "outside" on your RE050A tires. That's only thing you have to worry about.
As long as your "outside" side wall is facing outside, it's all good.
Thread pattern will not match but it is designed to use that way.
I was very confused when I got them first time. =)
