The mules' sidewall pressure will determine what I'll use, since the stockers are 44 psi and the newbies are 51 psi. The mules will make 2 of 3, so I'll change the pressure of the odd man out.

At 4 a.m., it's dark enough that I'd need to run lights, which would introduce another variable. I don't think I'll bother running on the C tires to the starting point, as I doubt it will be worth my time to swap tires for a 4 mile drive, when it's questionable whether the tires will even warm up. I will read inflation pressure and tire surface temperature (with an IR temperature) when I leave home, when I start each test, and when I end each test.

Starting the first A test with cold engine and bearings is going to mess me up, since all the other tests will have a warm engine and bearings. I think I'll run two A tests right off, to get the engine and bearings warmed up. Unfortunately, that's going to warm the tires up. I can't win for losing.
