I just ordered some new shoes for the Box yesterday :
https://www.tiresavings.com/tireShop.php?action=findMan2&manufacturer=Nexen&tirename=N3000&season=
$386 for a complete set ( $456 delivered )
I have had these on my car for 20k miles now and have been very pleased with their performance as a daily driver, autocrosser, and at the Tail of the Dragon.
May be a good alternative to the $1000 PS2's
