I suggest you to get Nitto DR 275/35/17 for daily driven tires. That's what my next tires gonna be. It's just impossible to get traction when you WOT at 1st,2nd and 3rd. DR handle good in dry but not as good in the rain. But who'll drive a 500+rwhp Z in the rain? Get a beater :P Thread wear? What thread wear? Expect tires change once a year if you are a regular drag racer. They are not expensive (like $160/tire). I know i can live with that. It's better than buying tires that will last a couple years but you can't WOT.
