Geo --I've run Hoosier DOT A6 radial tires 275-45-16 f/r on my 16x10 rims for may past years.. but they are not easy to drive on "streets".. better on highways... they will find and follow the grooves in the roadways, and because they are so sticky (40 TW) they do pickup lots of debris. BUT.. they stick like glue when autocrossing or on road race tracks (HSAX/HPDE).
The Hoosier DOT R6 simply takes longer to heat up.. better for HPDE events and longer life.
And now, Hoosier has made further improved versions.. A7 and R7.
I've also run Hoosier "Street TD" DOT bias ply tires 245-60-15 f/r on my factory Mopar 15x7 rally rims... again, a bit squirmish on streets, better on highways... and they stick great for competition events.
