1989 Nissan 240sx Tires

I've been drifting for over 15 years and these without a doubt were the worst tires I've ever used. They produced zero smoke and basically just turned to dust, then delaminated with about 80% tread left. I went through 8 tires in 3 hours while other people (with much more hp than me) drove then entire weekend (15+ hr) on a pair of kr20's. Embarassing.
