Well, go grab a piece of paper, a pen, and walk over to where your Boxster is, and write down the numbers that are on each side of the tire valve stem.
One number will most likely be like this:
7.5
8.5
The other number might simply be:
55
51
Write down the numbers from both the front and rear wheels, and post that info on here, and we can help you from that point.
Also, if you have the same numbers from the Cayman, that would be quite nice, also.
BC.
