My wagon has the 17's with 245/45's,,, still a little isolation from the road. A couple of other things,,,, the MB Tex seems a lot thinner than on my 95. we'll see how that plays out. The gas mileage IMHO is great. I have been getting 19 to 20 MPG around town and saw 27.5 out on the road,,,, not bad for a big wagon.
