Well after today got rained out,I fooled around with the truck.
After a smokey..smoke show at the neighbors house ,I launched it in
my drive way ..The pic attached shows the marks.
They are M/T E/T streets 28x13.50s with 20 psi,

The truck runs 12-o.s and on good day's will run 11.80s..

My times are -60' low 1.70s to 1.80s
MPHs are from 112-116
with an ET of 12.0s to 11.80s
It's a 12" wide wheel ,with tube's,not screwed ,just high tack.

Any suggestion's on why it's only grabbing on the outer edges
of the tire? It dose the same thing on the track BTW, I have tried
lower and higher pressure's ,and it dose the same thing????
