*Q: Car-wheel diameters seem to be increasing all the time. Is this just
a style trend, or are there technical and safety benefits that go with
it? I have a 1989 Volkswagen Vanagon syncro camper that needs new tires.
Should I also replace the 14-inch wheels on my vehicle with 16-inch
wheels? I'm told there is a greater choice of tires for the bigger wheel. *

A: Most of the large wheels you see are the result of style trends. But
there is a practical origin, too. High-performance cars often use bigger
wheels because they make room for bigger disc brakes�important for safe
and rapid deceleration from high speeds. Your proposed switch to 16-inch
wheels on your van sounds like a modest upgrade that will improve the
vehicle's looks. The change may also improve its ride and handling, in
part because what you've heard is true: There is a wider choice of good
tires for the 16-inch wheels.

I guess the questioner never heard of Vanagon.com!
