My dad bought this 2010 Mazda 3 new. It had tire noise from day one. The rear tires would develop cupping in just a few thousand miles. He had to rotate them often but that just helped mask the problem and never solved it. He went through several sets of tires of various quality brands and all had the cupping issue on the rear.
When I took over the car at 95,000 miles the first thing I did was ditch the stock steel wheels for a set of Enkei Compe wheels. I installed a set of Hankook tires in the stock size at the same time. I even reused the original TPMS sensor even thought they have to be getting near the end of the battery life.
I now have 15000 miles on these tires and so far there is no cupping whatsoever. I have rotated and balanced them every 5000 miles but the wear front to back is completely even.
Dad rode with me this weekend and he said the road noise is less than when it was new. He was amazed I was able to get rid of it.
We suppose that it must be the wheels since nothing else really changed. I am still running the original shocks and springs. I have not made any changes other than the wheels and tires.
At Track Night I noticed a whirring noise when I was idling
on grid in neutral. The noise would go
away if I mashed the clutch pedal. I had
heard a similar noise on the back straight at Road Atlanta back in February, so
I decided to check into it closer.
With the car on the lift idling in neutral, there was
definitely a noise coming from the middle of the torque tube. I decided it was time to change the bearings.
I read through the procedure on Clarks Garage. I also watched some Youtube videos. These looked intimidating, but I decided I had to give it a go.
I began by removing the shifter from the rod and the torque tube. I then removed the transaxle.
Just getting to Track Night was an adventure this time. I decided to try out my new to me Ford F250
tow vehicle. I first took the trailer to
work with me before heading down to Atlanta Motorsports Park.
