Update from the thread creator:

I did indeed have to swap out the front tires with 235/40's as the 245 would scrub in abrupt dip/turns (like into some parking lots) Now there is none. Also the 275's on the rear are fine and do not scrub at all. Note that this is with the Kleemann suspension upgrade which lowered the body a lot. The 245's may work on a non modified W210 chasis.
