Several years ago I followed the Postal Runs like the Silver State Classic. That where they go 90 miles on public roads. The idea is to make the drive as close as possible to a specific average speed. There are several different speed classes based on the safety equipment and tires on your car. There are several speed traps and you are disqualified if you are clocked going too fast for your class. There is an open class that averages typically 175 to 180mph. There have been several horrific crashes with deaths of both the driver and navigator. The crashes are almost always tire failure.

I never drive my tires faster than their speed rating and without checking proper pressure for those higher speeds.
