I ended up with a bunch of serviceable takeoff comp tires from the California Festival of Speed last weekend. Just when I had my tire storage almost cleared out.
This is the standard size for Boxster Spec and I am unloading these dirt cheap $20 ea, local cash and carry only- no shipping. They are recent vintage 2016 build date with no visible issues and plenty of rubber and grip left for a few days of hooning around the track in practice, DE, or Test & Tune. Bring a truck and get these outta here!
