Scion 05 Tc just has front two tires replaced Kumho Ecsta AST. I have older Kumho Ecsta AST in the back that are wore down but didn't have the cash flow to replace at the same time. I also got new brakes in front. I notice that between 40 and 50 mph i get a loud humming noise. I am thinking its the difference in the tread but not sure if the shop that did the work did something wrong? Any ideas anyone? The rear tires have some serious damage in the inner walls of the tire also looks like a patch of the tire is missing almost.

My guess would be a bad wheel bearing. Does the humming increase if you turn right or left?

98% positive its your tires...your wheel bearings should be fine....change your rear tires, then get an alignment. You have alignment wear on your tires

cupped tires

probably your tires. try balancing them and fix the alignment.

its probably your tires ... but check your sunroof seals they made a humming noise on me one at selective speeds and it sounded like it was wheels but idk probably just ure tires

if it sounds like a cricket its ur hood, only if it is cf... I am in the process of doing a diy on that..been busy

but humming is mostly the tires

i agree with what they said, probably your tires

wheel bearing = bad = can't drive

tires is probably the problem especially if it's humming
