Actually the real impact is sidewall flex. When you see Top Fuel
dragsters, what do you notice about the tires? Huge sidewalls
that flex
a whole lot. Big impact on traction. 16" combo's have far
more sidewall
than 17's. When I needed to replace my rims/tires (back when
I was
actively racing), as much as I wanted 17's for looks & handling
in turns,
I limited myself to 16's for traction.
You could opt to get whatever you like most for looks, and then have
a
cheap second set of 16's w/ drag tires.. Me, I just like to drive to
the
track, race, and drive off, I don't want to store 4 wheel's and swap
all
4 of them twice each time I race..
