275 40 R17 g-force R1s on all four corners, mounted on 17X9 wheels.
Running 40lbs of pressure. Car has about 2 degrees of negative camber, and some
toe out. Tires rotated front->rear at each event (so that the fronts at Event A
are the rears at Event B) Car spun 4 times, but has ABS.
24 runs - 12 on ultra-abrasive Ft Myers concrete, 8 on sealed pavement, 4 on
older aggregate pavement. Inside holographic tread is now gone, outside still
shows faint impression. Wear otherwise very even. No discernible flat spots.
Tires were scuffed in prior to first runs, but probably NOT properly heat
cycled.
Grip is much, MUCH better than the old R1s - but keep in mind I moved from a GS
car, so the comparison is probably not valid. Note that the car can now be
drifted....
I figure I'll flip the tires on the rims after Peru next weekend (at the 36-41
run mark, depending on if I (ha!) qualify for the (ha!) Challenge, and how far
(ha!) I get. (guffaw!)
At the current wear rate, I'm expecting to get 80+ runs from these tires.
