Sumitomo HTR Z
MT ET Street Radials lasted me 8,000 miles, and I babied the **** out of them. The cords were showing when removed.
Sumitomo HTRZ's have lasted me 25K miles and counting, they've still got easily 50% tread left.
Yes, the drag radials hook. No, the street tires dont. Surprise!

And that's great to hear that they have lasted you that long too. I am still expecting my front tires to last a lot longer than these Sumitomos though. I will be running those Nitto NT555's up front. I just can't spend so much on tires when the time comes around. My last car had the GS-D3 315/35/17 on the rear and those things were huge! But the price difference between one of those and these Sumitomos is what made me buy them to experiment with.
Ditto the post about "20K miles and only halfway worn down". Seem like a pretty good treadwear rating, although I forgot what it is actually. My '99 was a DD before I got my truck and I very rarely drove the car hard.
Ditto the post saying they are loud when you spin them. Yeah, they really scream in protest when you are boiling them.
