I can neither confirm nor refute this, tho I suspect
George is correct. For example, the data sheet for the
LT195/75R14/C Michelin XC LT4s which I am currently
running specifies 45 mph as a baseline for their
Revs/Mile of 824. One could reasonably speculate that
45 was perhaps selected as some sort of real-world
average betwixt city and highway driving, both of
which are far different from parked in the driveway.
As George suggests, it may even be an industry
standard
