With the proper pressures, DSC fully off, driving to the limit of the tire, but not over, severely overheating the tread like that isn't nearly the issue shown in this example. Under the same abuse, a full on track tire would show similar issues...heck the cords would be showing on an R7, lol.
Would camber plates help avoid that abuse to the outside edges? Oddly my worst wear on the PSS was the inner edge of the outer blocks. Not the very outside edge.
