Yes, which I do most of the time. If I put two new tires on, the rear tire wears much faster, so it's the "weaker" tire most of the time. After I replace it, it is better than the front, but quickly "catches up" to the front tire. Anyway, I've never had a problem with this. And I've only flatted a front tire once in the last couple of decades, while I've flatted more rear tires than I can count. Never broken a spoke on a front wheel, either, so I'm guessing the load on the front tire is much less than the rear tire anyway. And, now that I think of it, I've never flatted a single GP 4 Season. Hmmmm....

Strange thing about some auto makers, though. My sister in law bought a Mercedes 300, and the tires are different sizes on the front and rear, so you can't rotate them. I've noticed that on a few sport sedans. Not so much with my Outback, though.
