Tires

Curious..........................

Does anyone know the rational for Mercedes putting a lower profile tire on the rear of my S55 than on the front.

Rears are 265-40-18
Fronts are 245-45-18..

The question remains, why? What's the benefit of that set up versus equal size tires or even a reversal of that set up?

Since the rear tires are wider, they have to be lower profile in order to maintain the same diameter as the front tires.

Like sillydriver said.

The profile is stated as a ratio (percentage) of section width. Once you calculate it, you can see they are 106 and 110 MM respectively. The varience is small enough that the various computers don't mind the rotational difference
