Run. Run far. Run fast. I have had 2 sets of Kumhos and have been very happy, for about 10k miles. Then very disappointed. The 712s I have on my M5 are still above 50% but have NO traction left. The ASXs on my 325 wore out in less than 30k miles. I liked my Conti Extreme Contacts much more than the Kumhos, and they are the same price for my 325. YMMV -P |
