ShawnQ,

Go with a 16" and both BFGoodrich and Hoosier tire make 255/50-16 Drag Radials. If you use a tire calculator they have the overall same dimensions as the 19" rears. You can find Nitto's have 19" drag radials but they are a small fortune. I hear the hoosiers have the softest compound of the three brands. Most these tires brand new only have 6/32 of tread. Forget about TPMS.
