So would you agree that your post "Bald tires are better on dry roads" is at best not accurate,
since your Gary from Tire Rack actually stated that "...[i]ts true that slicks have the best dry traction...", which is a big difference from "bald" tires.

my thought on this
bald tires are bald from many miles of use over a long period of time which involves a lot of heat cycling. All that heat cycling turns the rubber hard which should negate the benefit of having more rubber touching the pavement. If you somehow have a realtively new tire with little to no tread the rubber may still have better "stick" to it and put it in the category of more grip than a treaded tire, but one with a few years and thousands of miles of use would be like running on a super hard compound slick.
I would say that your common passenger car tire falls into the super-hard slick category by the time it is down to the bars and would give up a lot of grip to a new high perf. treaded tire. On the flip side, a sub 140 tread rated tire would wear to the bars much quicker if used for a lot of autocrossing and such and may still have some grip in it even without tread.
In this person's case, I would not want to be someone around him on the road if it starts sprinkling out since the car would feel like drving on ice if the tires are truly without tread

Re: No
I just posted Gary's post to keep them out of legal trouble. One The Tire Rack's website they said this:
"any tread design breaks up the contact patch into smaller elements and additional deep tread depth (required to enhance wet traction) allows tread block squirm which will reduce dry performance. This means that tires typically provide their worst wet traction ... and their best dry performance just before they wear out.
