Strange noise when driving

[cybercabz]

Hi im new here and wanted to ask if any one knew.
i took my 2005 c class cdi for its regular service and told mechanics of strange noise while driving from wheels as though a bearing was shot like a humming grating noise when driving and clearer and heavier when applyin breaks and coming to a halt.

They said bearings were absolutely fine and nothing wrong and said its noise coming from cheap budget tyres a lot of people as this and its just noise from cheap budget tyres.

Is this true?

could it be a worn or breaking up abs ring on the hub? ive had this with other cars before . Never done one on a merc though sorry .Some one on here will know so dont worry Could also be the rear handbrake shoes beacuse they are hidden and a lot of mechanics are not used to em because they are like drum brakes in the rear disks.

from the front of the car its a heavey revolving sound.

You must be able to jack the front of the car and spin the wheels to hear what it is

My old 320 C ,class used to make a awful noise from the tyres, set of conti,s changed it 100%, handled better in the wet as well!

Cheaper tyres do make more noise on the whole - a tread thing I guess. May be silly but is the pressure OK, and even, or do you have a stone(s) in the tread? This drives me up the wall!!!!!

yer pressures okay/
just i had a few customwes and asked if i had a wheel bearing gone.

But when i had it serviced by merc authorised specialist gaeage tey said bearings fine just cheap budget tyres that make the noise.

I supose i just got to go with that for now may be i will know more after mot in 2 weeks
