Hi, i just installed E430 17x7.5 ET37 rims on my W124 4Matic...looks great, good clearrance but the only problem is when i drive up to 20mph a annoying sound from tires start...u can hear the tires rotating...this sound stops around 25 mph and begins again around 40...then stop about nother 10mph higher....wut is the reason for this?? Is it harming my braking system??? should i remove these rims and put back my stock ones??? plz help!!!

BTW the tires are 235/45/17 Pirelli P7000 Supersports...i think the 2 rear ones are about a little more than half a year old and the front ones are about 2 or 3 years old...maybe this will help

Your description of the sound isnt clear. Are you sure its the tires making the sound? Is it a groan? Is it metallic? Or does it sound like really bad road rumbling noise?

it sounds def. like the front 2 tires...there is no metallic noise because that would be very noticible...and the noise occers everywhere around 20mph regardless of road...the roise is more like brrrrrrmmm brrrrrrrrm brrrrrrrm...

Thats probably tires. Those supersports are notorious. I have heard more bad things than good about them.

Does the noise change if you turn at that steady speed? Does it get louder or quiter depending on which way you turn?

well i did a little experimenting of my own...i moved the tire to the back rear wheel and the noise moved to the rear...so this must mean it is a tire problem...thnx for the feedback from those who have contributed

I avoided those tires for that reason (noise)
