The same comparison suggests that the Michelin Pilot Sport 4S (
8.43) has exactly the same margin over the tire it's replacing, the Pilot Super Sport (
8.26). Or even less, if you look at that margin as a percentage of the total rating. I've owned both the Super Sport and the 4S back-to-back on the same car. I've even run them in pairs on different axles (e.g. 4S front, Super Sport rear) and swapped them back and forth. The 4S is a MAJOR improvement over the Super Sport. The reviews I've read suggest the same. All my friends who've owned both tires agree. Even Tire Rack, in their blurb summaries, had minor gripes about the Super Sport but literally ZERO gripes about the 4S. So if that's what a margin of 0.17 in those ratings means, I'd say your comparison proves my point about the DWS 06 nicely.
It doesn't prove my point about the DWS 06, of course. It doesn't prove anything on its own. Because these are averages of subjective ratings, from different tests, at different times, in different sets of conditions, against different sets of competitors.
Look at each number in the context of the competitors in each group, and... it's still super iffy, but marginally less so. Again, the G-Max was being compared against the tier-2 tires in that class, because it IS a tier-2 tire in that class. The DWS 06 is a tier-1 tire, so it was compared against other tier-1 tires. In that light, the true margin looks much bigger.
As an aside, common sense check: Continental owns General. They're not going to let General come that close to one of their best tires for two-thirds the money.

Agree 100%. Any OE tire is going to be slightly tweaked for the application, but yes -- the fact that it's OE on a production car says something about both the brand and the tire.
This isn't about the DWS 06 being good and the rest being bad. They're not bad. They're fine. The DWS 06 is better. That's the point here -- no more, no less.
