So i was driving today and i noticed my front passenger wheel was shaking vigorously.

I took the car to a friends tires shop and had him check it out.

He told me the tires look fine, he suggested i rebalanced the wheels.

When he put the wheels on the machine he told me i have 90 pounds of road force on my rear tires and standard is 25. He told me the belts inside the tires shifted and it happens often on pirellis. He rebalanced my wheels and suggested i have the dealer address this issue, tires with under 5000 miles should not need re-balancing.

I have 19s with pirellis, does anyone have any advice or info on this matter?

ps i dont really drive aggressively

The dealer claimed that yes the run flats offer an extremely harsh ride but the Pirellis are the least harsh of all of the options.. They recommended that I just switch to a regular tire and get an extra one as a spare. What in the world kind of option is that for a company that is supposed to be 1 of the world's greatest engineering firms? 1 by 1 each parelli has gotten louder and louder with the problem I was told being the belts shifting. The most recent Mercedes place that I went to said it may be it be a shot wheel bearing. Seriously, with 35000 miles?

I am running the OEM P Zero tires with zero issues, except that they get loud as they age.

Have them on 4 summer vehicles and none have needed rebalancing, currently still own 3 of them.

FWIW all will be replaced in the next year or 2 with the new Michelin Pilot AS4. Run flats are definitely a rougher ride than non-run flats, but I have never had issues having them balance properly.
