slim pickings indeed! After my last set of Exaltos wore out, I was in the same position as you.......threw the dice and put on Sumitomo htr p01 a/s. Initial impressions are they are very similar to the exaltos, whether they last 68,000 miles like the Exaltos did,who knows- but so far so good. Here is a link to tireracks test report on the sumitomos, they actually tested better than the exaltos......

Consumer Reports also had a very favorable review on them recently.
