2006 Chevy Cobalt 4 cyl Front Wheel Drive Automatic 27000 miles
I bought this car new. At about 20K miles the humming noise began. It sounded like from the tires. I was told about 20,000 miles is the limit. The car came with Perelli al weather tires 205/50R17. At 27,000 miles, I changed the tires to Yokohama 205/50ZR17 93W AVS ES100. The car handles easier, but the road noise humming is still just as loud as before. Any ideas?
