Default is rotating tires on a WRX really purposeful?

given that both sets of wheels are turning with the same force, is there much purpose to it?

only thing i could see different is the front tires getting slightly more wear from having to steer maybe

Absolutely.

...for varying definitions of "slightly". I wouldn't be at all surprised to see a rear set of tires last four or five times as long as the fronts, if they aren't rotated regularly.

Front tires will also wear more unevenly than rears, due to the castor of the wheel when you're turning and the increased friction on the outside edge. Moving them to the rear every few thousand miles will correct this.

There are also different ways of rotating tires to compensate for cupping and other unusual wear patterns. If your tires are wearing in strange ways and you can't pin the cause on something concrete (alignment, whatever), any competent tire person should be able to tell you how to rotate them to correct it. (Note that this doesn't apply to directional tread tires, which can only really be rotated one way.)

As if the tread life benefit wasn't enough, rotating your tires also gives you a chance to check the tire pressure regularly, as well as inspect your brake system.

In short, rotating your tires is a Good Thing. Do it.

Don't forget the front of the car is heavier than the rear. The front tires wear out just a little faster than the rears.

You should rotate your wheels MORE often with a Subaru.....they need to maintain as close as possible to the same OD to keep the center diff happy

You may drive a 'pushing pig', but I can assure you that I do not.

If your car is a 'pushing pig', then maybe you need to look at changing your setup.

This, combined with the fact that roughly 2/3 of your braking power comes from the front wheels is why the front tires on *almost* any car will wear faster. I say *almost* because if you are routinely pushing a high powered rear driver you can quickly roast the rears to nothing. My first car was a '71 Nova with a 350, and I found that out the hard way!

As stated above, the center differential is sensitive to different diameters, as it's job is to insure that the front and back wheels are moving at the same speed. I know my tranny makes a lot of racket on deceleration in 2nd and 3rd if the fronts don't have a few more pounds of air than the back, and I suspect it is a related issue.

All you need to do is inspect the tires. After 1-2 months of driving and 1 auto-x event I can clearly tell its time to rotate.

If you never put your tires to work (aka granny driving) you can go much longer w/out rotating, especially if you have a good alignment. But if thats the case then you bought the wrong car.
