Long lasting and ok grip but nothing compared to a good brand of tyre!!
But i paid $100 a tyre for my 17's and they lasted 10,000kms with me purposely trying to fry them, even 12 burnouts later at the off street drags, they were fine.
They only wore out due to the IRS camber on the Commodore, mate still has his Zeetexs on his R32 which he's had for 3 years and around 60,000kms!!
