It depends...

If you're strictly going by mph as measured by a tire, then it doesn't matter.  However, Mach is calculated as a percentage of the speed of sound.  At sea level, the speed of sound (mach 1.0) is about 660 mph.  At 35,000 feet, mach 1.0 is about 600 mph.  My witty sea level remark was directed at Ron's extra witty mach calculation... :-)

Regards,

Rob McCall
