i've been really happy with the 245/30/19 we have on the W208. like ocklasse said, the 452s have a very wide sidewall, and the fitment makes them feel wider than a 245.

however, i liked the sidewall stiffness, and lip protection the dunlop has to offer. its just a matter of personal preference, but i know for a fact the dunlop SP sport maxx tires will work perfectly for this application in the size that works best
