there's decent handful of true performance tires in 14" (falken azenis, nitto NT's, etc) but the problem is that they're all narrow (185's and 195's) and SHORT short, most running in the 23" range and they're "street" tires in spirit... like think about rain and you're on rollerskates and forget about any kind of mileage.
for the most part they're 150ish range a clip, but sometimes you can grab some close outs on tire rack for a little cheaper.
fwiw, in my dart i never found the limit of 205/50-15 falken azenis on the street, it took the track to exploit that level of grip.
