19 inch rims of on 4matic?
Tire size should be either 235/35-19 (0.7% difference from stock) or 245/35-19 (1.7% difference from stock; 245 is the size TireRack recommends for 19" rims).
The larger diameter wheels won't mess up your speedometer too much because the overall diameter of the wheel & tire remains fairly close.
If you go with the 245 size, you might have trouble using your stock spare tire because of the 1.7% diameter difference. Traction control might sense the speed mismatch between the spare and the 19-inchers and brake the spare.

Please keep me posted on this--sorry to dig up an old thread!

Maybe we could get a discount for ordering two sets? $500 is not bad at all if it comes with shocks or is a coilover kit.

The Tirerack suggested "plus" tires sizes include the weight capacity for each tire. In some cases, by going down the next width size, so does the overall weight capacity. I am not sure if this is the case here, as I have not reviewed the differences of 19" tires.
