Tires are holding up pretty well, actually. Siping took about 10' off my dry pavement burnouts. I keep meaning to have Lilpooky or Jseabert film a good burnout. I did one last summer right in front of the houses for Jseabert and his family. His brother'* measured it at about 40'. I have a pic of the aftermath somewhere.
A burnout like that means nothing more than overmatched power vs. undermatched rubber. Next tires will stick a bit better. Right now, I'll consider my tires as a 'safety' for the transmission
