17" versus 14" tires
The conventional wisdom about more tire choices on 17s may not be quite what it sounds. Yes. there are modern/sticky tires available in 17" but if you're looking for a 17" performance/non drag tire that is taller than 25" (as most of us are) you have your work cut out for you.
At least that was my experience...maybe that's changed since a year and a half ago?
