In the world of drag radials, the BFGs do tend to be more street than drag, compared to others, so they do behave better on the street than a comparable M/T or Hoosier. However, they are still desinged with a softer sidewall section and even BFG only rates them average for handling and braking performance.
One of the more extensive and long running topics on 15" tires can be found here:
http://www.pro-touring.com/showthread.ph...;highlight=avonPickings are slim, but if you flat out refuse to step up the rim size, there are some 15" tires out there. Be prepared to pay though, as a V or Z rated 15" tire is going to cost you upwards of $300 per tire. Plus, while some of these may be d.o.t. rated, they are still designed as a race tire so you have similar wet weather performance issues as a drag radial and life expectantcy is low.
If you are so inclined, Summit still sells the old M/T road race style "I" compound tires in wide (like N50 or 315mm) 15" sizes with 4 ply sidewalls. Only drawback is they are old school bias belted designs and not heavily advertised so you have to dig deep through their search engine to find them.
