The roads here on the coast are not so good. They re-pave and the earth settles and the bumps and dips return. As far as the front goes, I guess the shorter sidewall aids steering response. Conti DW comes in a 235/45 & 265/40 size, increasing the sidewall about a 1/3" compared to OEM sizes. I want to go with the PSS though when I replace my originals, so it's either 225/45 & 265/40 (assuming just one size larger in the rear will have minimal affect on understeer), or 235/40 & 265/35.

John, see my post above about slight liner rubbing I had with my 265 Star Spec rear tires.

I had not driven more than half a year on factory-sized tires so I can't really give you any feedback on bump absorption - I doubt if I noticed much difference. If you went to >18" wheels I would get concerned.
