Hey all... I just wanted to share a positive experience in case anyone is looking for tires for a Boxster. I put on a set of Michelin Pilot Sport PS2 tires last week. So far in both dry weather and in torrential rain, they have been outstanding. I had pilot sports before, and these feel grippier and are noticeably quieter.
I am certain that they will not last very long... but you pretty much have to decide whether that is worth the tradeoff. I'll be happy to get 15,000 miles out of them. But, those 15,000 miles should be a lot of fun.
They have these tires at Costco for $1032 for a set of 4. Most places will come pretty close to matching that price. Watch out where you bring the car though, I brought my car to one shop that had no clue how to even get a Boxster on its lift -- then went to another that had no trouble at all.
