Just installed my fifth set of tires at 154,000 miles. This is my third set of Pirelli Scorpion Zero's. Although they only last about 35,000 miles, I love these tires. Thanks to Tone for the research.
My experience is with the Bridgstones (of course), and then I tried the Yokohamas. Yokohama was a good tire but got rough very fast the way the tread wore. I rotate and balance every 5,000 miles along with my oil changes. It is more convenient to combine things and easier to remember at 5-10-15-20 etc.
I probably will get a couple more years out of my Ironman and then I am going to be very upset because there is nothing on the road currently I would rather have than my VX. I sure wish Toyota would announce production of their FJ Cruiser.

P.S. Yokohama AV-ST's are the type I tried.
