Re:
For what it's worth, I picked up a set of new 345-35-18 Bridgestone Expedia S-01 matched asymmetric that are no longer available (discontinued for whatever reason...I think the date stamp on these decode to a 2003 year of manufacture). They are a little wider than the 335-30's Pilots, but almost an inch taller. With my new Elbach springs, these tires really fill the rear wheel well and bite like crazy (of course the Pilots were getting a bit wore/hard). Other than going with a 19" set-up, not many choices to get into a 345 series in an 18" tire.
