I like that phrase "up to 15,000 miles of tread life of normal street-driving use". That means, of course, ****y-footing around on the street which I would never be able to do with those tires on the rear. I'd light 'em up every chance I had so I'd be lucky to get 5,000 miles. Years back, we had a recapper in Pasadena that put soft compound on good casings for all us nuts that loved autocross/gymkana racing on weekends. We had two sets of tires and changed them out the night before we went racing. Only way to go. So what's a set of Nitto's and wheels going to go for as a "weekend" set. I know, I know. I'd probably "forget" to rotate them off after the weekend.
