If there was any way to prove it, I'd bet dollars to donuts that the rims were swapped-out on the showroom floor. Someone bought the car next to it and wanted 16" Fuchs instead of the 15"s it had. They switched them to make the other car go away. No one would ever go and switch the other way, unless maybe if his wheels were stolen and the 15s are replacements.

I'd listen to javadog, he knows these cars. :)

Or, maybe they were like me and sold off a pair of perfectly good 7&8x16 wheels and bought a pair of 7&8x15 wheels to save a few pounds...

NICE car, Mike.

You can do the valve adj. yourself - not that hard. Procedure in the Pelican tech articles.

CONGRATS!

I suppose. Softer ride on taller tires, as well. I think that the overall diameter of the respective stock tires is about the same, so no slight gearing advantage or such. I have rarely seen a 911SC or Carrera on 15" Fuchs but have a few times. :cool:

The lighter weight can be felt while driving. When Pirelli ushered in the era of low profile tires with the P7, you could get your 7 x 15 and 8 x 15 wheels fitted with 205/50 and 225/50 tires. It was something you saw on the early 3.0 turbos, before Porsche introduced the 16 inch Fuchs. So, a gearing advantage is available, too. Porsche even fitted those cars with a speedometer calibrated to the shorter tires.

15" tires are a little tougher to find these days, but not impossible.

Do your own valve adjustment. I call BS on "hearing" that it needs valve adjustment. The valve seat wears faster than the rockers and stem, so valves sink into the head and the valve adjustment gap actually gets tighter over time, not looser and noisier.

It seems to be easier to find 15 inch sizes than 16 inch sizes for the most desirable street tires. Cheaper, too. At least based on my experiences trying to find tires for my Elise.
