I have a C coupe with 16 X 7 OEM wheels.
I switched to 225/50-16 Yokohama ES100.
Fit just fine, handling is much better than
the stock 205/65-16's. Turn-in is crisper,
and ultimate grip is much higher. The
ES100 isn't the most agressive rubber you
can get, it's a compromise of good performance
at a reasonable price. I'm partial to
Bridgestone or Yokohama because I've had
great satisfaction with them. A Bridgestone
RE730 would be a good higher performance choice too.
I did note a 2mpg average hit, with this new
rubber. It's due to the it being higher performance
(stickier) and wider (friction).
Going 17" is a big investment. I too am in
NorCal and run 17" 40 series tires on other
cars. Nothing but heartache with damaged tires
or rims due to our shitty roads and the potholes
after this recent rainy spell haven't yet begun
to get patched. 17"s do look and handle better,
but the cost is more than double that in the
long run, vs. upgrading the 16" stocks.
