The problem with radials is they have to be warm or they'll be worse for traction than street tires, so it really depends on the surface you're on and if you can heat them up prior to. I normally race on no prep, and the OEM 19" pirelli are the most consistent tires I've personally seen. Tesla Plaid Channel says the same thing, except he runs mostly on prepped surfaces.
Usually what I would do is keep the car in drag mode for the battery heat, then when I pull up to the line I would put in track mode, -10 stability, 100-0 rwd and do 2 dry hops to clean off and spin the tires just a little. Then put back in normal mode and tap it full throttle once before going into drag mode (or normal mode depending on the surface) for staging.
Dry hopping is track mode doesn't help a lot more, but it does let it turn over the tires just a little more, and any little bit helps.
