something else to consider. with your 19" tires you have a very small sidewall which in nature has little flex. so high rpm launches cause wheel spin.
the reason many of us use the 16" drag radial is we now have a 255/50 sidewall which allows a much lower tire pressure( i run between 18 and 22 lbs) which in turn allows more sidewall flex allowing a higher rpm launch without wheelspin. i can launch my 32 at almost 2000 rpm without spinning on my goodyears. downside is i crunched my rear diff!!
240srtm3 also showed us with his 60 ft times that wider isnt always better. he had massive 305 tires and his 60's werent any better than with his 255 dr's
all this said its really better to run good street tires on the street and dr's on the track. there is no 1 tire that is great for both (mt et streets are the closest but suck in the rain and are the heaviest of the dr's)
weigh your nittos and rims. clk rims in 16" with my goodyears weigh in at 39 lbs. stickey and lightweight
