I have a growling noise at aprox 19 to 25 mph the dealer says its tires but I dont think so.

If you have Bridgestones it's almost guaranteed it's the tires. They're terribly noisy whenever they want to be, esp. after a tire rotation, or heavy use, or just for no good reason to annoy you. Mazda must get them real cheap, or at least they should.

It's due to the fact they are run flat.
