Isn't wheel hop and smoking the tires in a straight line a reflection of the stickiness of the tires?

I run 17 inch cup wheels with Yokohama AVS 255/40 17 tires. Incredible grip with these rear tires on dry conditions. Not satisfied with the grip on the Yokohama front tires, as they seem to have become too hard now. It seems to me as well that it has too much grip to come loose. Have had some hop on my winter tires during standstill acceleration as well. Run same dimensions here. But normally on slippery conditions I never have the "hop"

Interesting to hear that your 18" tires slips.

Experienced the rear tires suddenly loosing grip on dry conditions in a sharp 4 lane turn in about 125 km/h during acceleration, first time it has hit so suddenly: lots of grip, grip, grip, oooops no grip. Luckily, kept the foot on the gas and pulled it in, (dredding the sledgehammer backswing)

Stats here, I found these on a website ages ago, but can't remember which one, so sorry for the lack of credit:
