2007 S60: Dirty Front Wheels

May 08, 2008 13 Replies

I bought a 2007 S60 2.5T demo with about 6,000 miles on it last November. It now has about 13,000 miles. I love the car but it has one peculiarity that I find puzzling.



The wheels are the alloy type with five segments and double spokes between. The front wheels get a gritty black coating and the back wheels don't. This black film washes off easily but I can't come up with a good reason why the front wheels get dirty so soon after washing. Since the engine is up front, it may be something from the engine; turbo blow-by, a rubber belt atomizing, engine coolant reacting with cosmic rays, whatever. Or it may be that the front tires stir up the road dirt and it's blown away by the time the rear tires get there.



Not a real problem, just a puzzlement.

brake dust.......go to your local auto parts store and get some cleaner and a brush.....they will look like new...careful w/the wheels...they can be damaged if you use the wrong cleaner....

You're joking - aren't you?? Seriously, just stirring for a reaction?

I use a pressure washer (1300 psi) to clean the wheels. It makes life about ten times easier. Also use it to make the car wet and rinse after hand wash with Meguiar car detergent.

If using a pressure washer, make sure you use a low psi, like 1300. Otherwise, you could be removing the paint from your car.

P.S. Never use a chamois to dry it up. You'll only be dragging tiny particles over the paint and scratch it. I use old bath cloth.

yea, i have heard some of the high pressure washers can not only remove paint...but blast a hole in your skin....be careful w/them...

Not at 1300 psi. It is so gentle you can easily put your hand right in front of it. Mags used to be a pain to clean, but with a gentle p.w. it is a piece of cake. I actually look forwards to cleaning the Volvo.

This is the one I use,

It will do "ok" for cleaning the deck, but it gonna take you a LONG time. I've been using it for a few years and LOVE to clean the mags. Doesn't consume a lot of water.

I would return the car! :-)

I wonder if the obvious has truly gone by him or maybe he's just trolling? Just in case he really doesn't know, the wheels get dirty from material worn off the brake pads. The front brakes do approximately 80% of the braking effort so the pads wear much more quickly.

I have cut my hand with the jet from a pressure washer. It is very slow to heal.

it dosen't take much pressure to bend a fin....

That's disc pad dust. It's a problem for any car with front wheel disc brakes, which by my estimation would be almost any modern car on the road by now.

Like I said, use a LOW pressure washer. 1300 psi is safe enough. The one I mentionned is a gentle one. It is for this reason I bought the weakest p.w. I could find. Prevents me from doing damages. And it is great for cleaning the mags!
