Tire rotation on 4matic - when and how?

Hello, I've recently put 10k miles on my used 2002 E320 4matic wagon (from 37k to 47k). When I brought it for an A service at the dealership, I asked about a tire rotation. The service manager discouraged it, saying they didn't know when to rotate the tires because this was the first time they saw the car and didn't know the tire's history.

Um, but it's been 10k miles, shouldn't they be rotated? How can I diagnose that the tires need rotation? ie, where do I check for wear? And when I bring it back (or to an indy) for rotation, what's the rotation pattern for a 4matic wagon?

I think my alignment's off a bit which may wear the tires more. Where should I look for that? And it is even remotely possible for ANY DAMN mechanic to fix alignment? Every car I've ever owned is always out of alignment and no matter how many times I request it be fixed, it never is. That slight misalignment really wears on my wrists and arms from constantly fighting the wheel. Any tips would help. Thanks!

Thanks. I'm surprised that I shouldn't rotate the tires. I'll double check the owner's manual (ha, my first instinct is always to browse/ask the forum).

You should rotate your tires at least every 5,000 miles, and should consider a 3,000 mile interval if you have fast-wearing performance tires.

Rotation is especially important on a 4matic because uneven front-to-rear wear puts unnecessary strain the drivetrain. (The rear tires on my 4matic wear about twice as fast as the fronts.)

As for the pattern, try B or C on this page:

I rotate mine twice a year, when the summers come off and the winters go on.

The tires with the most tread go on the rear everytime, but I do rotate LF-LR and RF-RR, then LR-LF and RR-RF.

When rotating tires be very careful that you don't have unidirectional tires. If you do, the must remain on the same side of the car. Just exchange the front and rear on the same side. Unidirectional tires will have an arrow on the sidewall that point to the front of the car as the direction of rotation. If you put them on the wrong side, your tread pattern is pointing in the wrong direction, which will affect handling.
