How many people looking at a stylish SUV think that those wheels look
like they steer better?

Maybe I'm wrong that people try to replicate an image of speed and handling
(e.g., why do people put M3 badges on a non-M3 bimmer then?).

Anyway, I just want to know what the performance impact is of a larger
diameter change of one inch.

This Car and Driver article tries to answer the question:
Effects of Upsized Wheels and Tires Tested
http://www.caranddriver.com/features...d-tires-tested

"What¢s immediately apparent from the results is that as the wheel-and-tire
packages get larger and heavier, acceleration and fuel economy suffer.
Neither is a huge surprise, but we measured a 10-percent drop in fuel
economy and a four-percent degradation in 0-to-60-mph acceleration from the
15s to the 19s"

what my Ranger looks like with the "big boots" on.
If I drive very conservatively I CAN get a bit better mileage than
with the original small tires, but generally speaking, in normal
driving there is little if any improvement -and around town, it is
slightly worse. The truck works harder every time it starts from a
stop or accellerates at low speed. I'm willing to put up with that on
a 21 year old truck with about 350000km on it, to have the "look" I
wanted. It is not a "performance" look - - -
