Do I have a slipped belt inside of one of my front tires?
Car: 2011 Infiniti G37S sedan with 225/50/18 front and 245/45/18 rear, 97K miles on car.
Problem: About two weeks ago the car started making excessive noise in the front. Sounds like a wheel bearing or tire noise. The noise has gotten worse over the last two weeks or so. The noise I can hear comes on at around 15-20 mph. After that road noise drowns it out. I also get steering wheel vibration at around 65-80 mph. After about 85-95 mph the vibration goes away. The strange thing is after about 10 miles of driving the vibration goes away at any speed. In those 10 miles, sometimes it feels like the front wheels are "bouncing" at highway speed. It's like a rhythmic cyclic bouncing sensation.
What I've done so far: The car has brand new front hubs and bearings (both sides), brand new rotors and pads all around. Discount tire did a Road-Force balance and wheel matched the tires to the rims. I've had the front tires balance 3 times and the problem persists. Discount tire says that they are balanced. They did not notify me of any bulges or irregularities in the tires.
Thoughts: The only thing I can think of is that one or both of the front tires has a slipped belt. The tires have about 38K miles on them. They are rated for 80k. The tires are General Altimax RT43. This car drives absolutely great otherwise and is dead reliable. Just want to fix this annoying problem. I don't mind spending money to get new front tires, but if it something else I am open to suggestions.
Thank you!
