I have always been a fan of Kumho V700. However, Supra 712 is a different story. The sidewall is too soft comparing to Yoko A520 or any other manufacturer. On 215-40ZR16 is no problem with Yoko 520 at all. Had 3 Supra 712 with tumors / Sidewall bubble (so far) on less than 10,000 miles (since November 2000). On one of them brand new with less 1,000 mile. Got these from Tirerack and they gave a wholesale price. Tirerack did not even bother to offer to look at my tire. The tire with about 10,000 mile was shredded to pieces on the freeway. Today, another tire with only 3,000 miles is bubbling on the inside again. The tire would bubble differently after so many miles. My Lude is stock with nothing done to it. Called Kumho customer service today. It's easier to get the Virgin out of Mary then get Kumho to ackowledge some type of credit.
Just stay away from Supra 712 and save headaches. Get what you paid for!
