Analysis of 18 by 8 inch wheels on a 124
    My wheels are Carlsson 1/6 Evo Diamond. The wheels are beautiful and can only be fully appreciated when seen in person. The wheels are 18 by 8 with an offset of 35. I have experienced some problems with rubbing on only the front fenders and wheel wells. I have also experienced a little tire damage to the fenders.

As one can see the wheels do not protrude from the front fenders, the wheels are flush or slightly set back.


Here is another view of the front wheels and the fenders, this picture may be a bit deceptive because the picture was taken from an angle.

    As one can see in this picture there is some damage to the body cladding caused by the larger 18 inch tires. In the circled area one can see what damage has been done. The cause of  the rubbing in the circled area was from hard braking. If one looks at the protrusion of the fender highlighted by the arrow, one may notice how the protrusion may come in contact with the tire (the other side of the car did not have such a protrusion). In fact I did have some tire damage from this protrusion, the tire had a small chunk taken out of it which is not that noticeable. I have since fixed this problem by bending the protrusion in with some slight persuasion from a hammer, I now have no new tire damage.

    Here is a picture of the fender and body cladding after I have bent the fender in a bit and cut away the body cladding. One can now see that the protrusion has been eliminated, and how the body cladding has worn over time.

    It is hard to see in this picture but this is another place in which the tires rub. The rubbing in this picture is caused when going over bumps at moderate speed.
    This picture better illustrates the rubbing of the front fenders. One can also see that the fender has been slightly bent. The bend happened when I was turing into a parking lot and encountered a server gully. The bend is not that noticeable and can only be seen if one is looking for it.

    The final place in which the tires are rubbing on my car is in the inner fender near the struts. One can see the effects of the rubbing in the picture above. The rubbing is not that major, the factory coating has not even been rubbed off yet. I do not have a solution for this problem, I have tried hammering out the fender (as is evident in the picture) however I did not get any real results from my attempts, if I spend more time hammering I may be able to get better results.

    To fix the minor rubbing problem that I have I have rolled the fenders, rolling the fenders has also solve any cosmetic problems that I have had. Look here for more information on Rolling Fenders. It may seem as if 18 inch wheels on a 124 is a big pain but it reallay is not, after having the wheels on my car of a few hundred miles the frequency of rubbing has been reduced. When the wheels do rub it is only when I have run over a bump going to fast or making very very hard turns. Keep in mind that my car is lowered using Eibach springs with #1 pads all around (spring pads are a shim that Mercedes puts on their cars for the adjusting of ride height), and Bilstein Sport shocks. For me the advantages of 18 inch wheels far out  weigh the disadvantages, not only do I get far greater handling improvements but the wheels have updated the look of my E420.
