Tire cupping/road noise
 

I have an 07 Mazda 3 hatchback with about 68000 miles with extremly loud road noise caused by cupping tires. Has anyone here had to replace thier suspension yet? How can I tell if my shocks and struts are bad and what should I replace them with?

if you have the stock tires, replace them, they are garbage off the bat. are the cupped tires in the rear?

Cupping/road noise
 

The tires I have are the Bridgestone G019 Grid. Maybe 20K on them but the noise has been there for some time. I've read that when front wheel drive cars first came out there was a problem with cupping in the rear because of the lack of weight but surely this cant be the case in 2007.

I'm not to sure about there the cupping started since I've been rotating and balancing to try to get rid of the noise. I put them in the back and havent noticed cupping in the front tires.

the reason most likely is that from factory our cars come with about 1-1.2 neg camber in the rear, this causes quite a bit of wear quickly. Id go to a shop and get your alignment checked just in case and replace the tires since they are causing so much road noise
