When they were inspected there were clear signs
of delamination where the side wall meets the
Tread block, the vulcanisation was breaking
away, it was almost like the softer side wall was
tearing away from the tread belt.

He had used them because he was using the Track day
to dial in some new AST Comp Coilovers and conceeded
that he had made a costly mistake, in that the afternoon
was all but lost, and the tyres did not even last the day.

His car is 1130 Kg's without driver.

Most of the Budget type 'R' Track tyres suffer similar
problems even more so when used on cars weighing
in at over 1100/1200kg's.

That said even the MX5 Crowd have not been overly impressed
with them, saying they are worse than slicks if it rains.

maybe same guy as my guy had delamination area as well
