I'd love to see a wet and dry skid-pad comparison including the Nittos, Sumi's, Toyo's and GSD3s.

All I have to go by are the Nitto "555" and "555R" vs. the 'D3s.

Warm, dry weather and especially at the drag strip, the Nitto 555R sticks much better than the 'D3s, especially noticed the difference with the 13# Fidanza.

In rain or on wet pavement, the 'D3s are tops; NO CONTEST. In fact, the 555R (drag radial) gets very squirrely around 45+ mph, depending on the amount of water on the highway.

And, when it gets down to freezing, neither tire is particularly safe, IMO.

I almost never drive on snow. But, I have tried to drive across the yard with the 555Rs: forgetaboutit!! Might as well be slicks!

So, In my experience, and especially in warm weather (read: pavement is warm/hot) I prefer the Nittos to the D3's...unless it is raining.

But, Nitto also makes the "G2" tire which is apparently a much better all-round wet/dry tire (especially WET). Maybe Robert Demarco can offer his subjective opinion.

Like I said: sure would like to see a skid pad comparison.
