I have 10,000 mi on a set of Primacy HP's, 18's, on my 2007 GS 350. Felt vibration and rhythmic roaring and the dealer says its feathering of the tires. Says I can drive it like it is or replace them. Tires were bought at Tire Rack.

The car has had all scheduled services and aligned twice since the tires were installed. Also, I am easy on the car with driving habits.

Is this tire just not strong enough for the suspension? Help! Thx ahead.
