Yokohama AS430

I have owned 4 Porsche 944/968's (still have an '89 944 and a '95 968) plus BMW 5 and Mercedes E sedans. I've driven over 500,000 miles in these cars and had experiences with many different tires. My first 944 had Pirelli's on it and I hated those. Good dry handling but dangerous when wet, and they wore out really fast. I used Michelin Pilots on the sedans and was happy with them, but not at all for the sports cars (once was enough there...Pilots are not performance tires). I tried Kumho's and was happy but not elated, and then my friend at Big O tires recommended Yokohama AS430's. That was years ago and I've been using them since. I recently purchased a 1995 968 that's got Michelin Pilots on them. I don't need new tires yet, but I'm going in today to "upgrade" to the Yokohama's. The Michelins are loud, almost impossible to balance (could be mildly flat spotted, but we can't find them) and tracks poorly on uneven roads. I don't race at all, so for every day driving the Yokohama's are as close to perfect as one can expect. (Ps: My first set of AS430's were replaced after 7 years and over 50,000 miles only because they were getting too old and becoming brittle from being parked outside in the sun. The treads still looked at about 60% left).
