The new-to-me '14 MZ5 Sport w/ 30K miles has brand new Goodride SP06 tires in the front. Not a very popular name but tires have good ratings online. The rears are Toyo A20's. They have different date codes as far as I can tell. Also, one A20 appears to be brand new judging by both appearance and tread depth whereas the other one is at about 60-70% tread. I'm guessing that the dealer, CarMax, replaced two original tires (Toyo A20's?) with Goodrides, left one original Toyo A20 but then put one new Toyo A20 on. Odd.
So now about the noise. The higher the speed the louder is the noise from the rear. Almost kind of like worn wheel bearing but not exactly. My guess is it's the tires. Aren't Toyo A20 noisy and overall a pretty bad tire? Or are these cars just noisy period (which I realize is subjective and depends on what driver is used to)? Any thoughts would be helpful and appreciated.
