with street tires, (bf goodrich radial t/a's), would it help a launch at the track to do a good burnout?

i can't get any traction off the line with these, (i know, i have them for the looks. one day i'll get another set of rims and some drag radials...), and was wondering if heating them up will help a bit.

was told no by someone, but just wanted some other opinions.

and on the subject, what is the best drag radial out there? i need something in a 275/60 15. might be able to get a 285 under there.
