Hi to all,
I checked the tire size this weekend to be sure, since it's been too long for
trivia in the memory cells, They are 195-60R14.
Several folk have asked to see a picture of them. Steve has a photo (last one
in the article) on the Tigers United site for easy viewing. It is

The "V" insert is a round piece of steel approximately 1" in diameter which is
flat on one side and the other is a concave surface that slopes at the same
angle as a lug nut exterior. It has a clearance hole through the center that
the lug bolt passes through. The hemispherical lug hole (stock Porsche) on the
wheel, is bored out to a counterbored hole with step shoulder that gets the
steel piece pressed into it. This just gives a nice hard mating surface that
the lug nut can seat on. It is prcision machined to give proper "centering" of
the wheel.
Just a point of reference, Before mounting tires on these wheels, I mounted
each wheel, on the right front hub, one at a time and slowly rotated them by
hand used a dial indicator against the wheel edge to check for "wobble". Out of
the five wheels that were machined and measured, the worst case "wobble" was on
the order of +/- 0.002 ". Several of them were less than this value. I was very
happy to see this degree of accuracy, especially, in factory wheels. I'm fairly
sure the molded rubber in the tire is nowhere close to this accuracy.
