I recently had two new tires put on my car a few months ago. I noticed immediately that the tires were much more noisy than the other brand (still have the other brand on the back of car). After living with the noise for awhile, I decided to go into my Nissan Dealership for a 90K service. I mentioned the noisy tires, and now all of a sudden they want to charge me $370 ish for a front left wheel bearing. The noise never started until I got the new tires. Do you think they might be trying to rip me off? Should I get a second opinion??
