not in my case. once my tires hit about 100 runs, i have MUCH less traction
than with my 400 treadwear other tires.
borden recorded 1.47 G's on good hooisers, 1.2 G's on RE71 street tires and
1.1 G's on hooisers with 60+ runs on them.
then again, ive got a light car with big tires, so they heat cycle to
hardness before the rubber wears out.
YMMV,
