Effect of a repair on speed rating of a tire
I managed to pick up a screw during my weekend at the Texas Mile, in a brand new Pilot Super Sport, and was wondering what the effect of this on the speed rating of the tire is? I would love to hear that it's still safe to run at speed, but I suspect that is not the case. How likely is it to have a catastrophic failure by picking up a screw or nail and making a high speed pass?

The Tire Rack has some good info on how a puncture repair affects high performance tires. This chart shows what the manufacturers say.
It's very important to make sure the repair is done properly using the proper patches and procedures. Where on the tire did the screw enter? Shops wil typically not repair any puncture if the hole is within one inch of the edge of the tread or no repairs at all if the hole is at the edge of the tread or on the tire sidewall.

...Therefore, most tire manufacturers have established policies that a punctured and repaired tire no longer retains its speed rating and should be treated as a non-speed rated tire driven no faster than 85 mph.
