Tread compounds, preparation , and use will be the determining factors.
Top rated street design tires have proven to be the best.
Proper preparation and responsible use have seen them run over 260.
The same tire might have a failure at under 200 if not applied correctly.
The bike safety record owes it's success to the forewarning the tires give a rider before a catastrophic failure that will put you on your head.
The shared experience level with responsible inspection is going to do the best testing and is what keeps the sport going.

I think the Metzler should be just fine.

The Mickey Thompson 17" ET Drag slick is what they had in mind.
Well, it used to be Los Angeles . . . 50 miles north of Fresno now.
Just remember . . . It isn't life or death.
It's bigger than life or death! It's RACING.

I got a quick reply from a SCTA tech person, and as I suspected, the new "Drag slicks not allowed" rule change applies only to rear tires.

 We used to run an 18" rear Goodyear square corner slick, but it had a good crown to it when pumped up to the maximum PSI....worked pretty good below 150 mph, but thin sidewall constuction became a concern. That new Metzler looks pretty square edged....bbb, I would send a picture to the SCTA tech people before showing up at a race with it.  If it is designed for drag racing , you might get gonged.  Better to be safe than sorry.

The squared off corners are what will cause the first problem when you get a little out of shape with a tire that is designed to always run straight up.
Moving the contact patch off center on a square tire will give you a really exciting ride.
Most of the tires that are designed for drive use on a Drag Bike are too soft to be very useful for LSR anyway reguardless of the designed shape.
That make ruling them out easier.
