While drag radials certainly don't have the "lasting power" of street tires, that's not really the issue, or is it?
From a safety standpoint, of course, no one wants a blowout at any speed, but there isn't/shouldn't be the
expectation of longevity on any part being pushed to its limit. That being said, we run a 295/40/17 M/T drag
radial (ET Street II) on our Camaro at a median (~25) psi. Checking tread, pressure rise, sidewall temp, etc.
are all best practices while racing; great point on that Fheckro. Ours have approximately 30 miles on them
and have held up very well.
