Last February, I replaced my Goodyear Eagles on my 99 Intrepid with Michelin
Hydroedge tires. Since then, I have driven about 5,000 kilometers or about
3,000 miles. I had some routine service done at my Chrysler dealership
which included rotation of the tires. Yesterday, I noticed a slight
vibration when driving on the highway at about 100 km/hour or 60 mph. I
took the car to the tire dealer where I purchased the Michelins and was
advised all four tires were out of balance and should be routinely
re-balanced every 20,000 km or 15,000 miles (every second rotation) whether
there is a vibration or not.
I have owned cars for 35 years and haven't had this mentioned to me. The
tire dealer was shocked I was unaware of this 'rule' of tire care. I drive
about 12,000 miles a year, mostly in the city and am very easy on the car.
Is there someone who can agree or disagree with the comments of the tire
dealer? Do ultra premium tires have to be re-balanced every second
rotation?

No. I have about 17,000 miles on my hydroedge tires on a Chrysler mini-van
and they are still perfect. I have not yet rotated them yet, but will next
spring after the show tires come off. Be sure to check that they did not
switch sides since these tires are directional.

I wonder if the new larger diameter wheels and tires are more sensitive to
out-of-balance condition than the traditional 13 to 15 inch sizes?
I know wheels tend to drift out of balance with use. In my opinion,
on-the-car balance is best because you balance all the rotating mass,
including drums and discs. Also, you can visualize the final balance and
actually test the final balance by running up the wheel-tire assembly with
the drive motor or engine. In school we used an old Hunter balancer and it
was good for 100 mph they tell me.

Yes, tires do need to be rebalanced as they wear. I'm not sure about that
interval (15000 miles), I just get 'em rebalaced when I notice a problem.
If you do very little highway driving, you may never notice.
