Found some cheap 22's. Found a good deal on some tires that come highly recommended by the Cayenne boards at Discount Tire. They mounted and road force balanced for only $16, but wouldn't put em on the Cayenne because the load rating is 25lbs a wheel lower than Porsche's spec. arrrgh.
Got one wheel swapped and when I went to lift the truck for the next one my 30 yo Sears floor jack blew out. Nothing is ever easy.
Went over to Glen's Garage and we got the other 3 wheels swapped. Thanks again Glen.
Guess I'm going to have to change my name cuz I'm rollin solid with 22s. Maybe Pimp Stick.
They ride great, can hardly wait to see it in daylight.
