Has anyone verified these numbers on modern radial tires? I have trouble
believing that any radial tire available has the high profile of the old
bias-plys found on our cars originally when they were spec'd.
Just for comparison, with 3.89 gears and low profile 205/60-13 Potenzas on my
Series V, I'm turning around 14.75 mph per 1000 rpm's in fourth. I checked
the tach out not too long ago and it was relatively accurate. Verification
of speed (trust my speedo? HA!) has been by pacing a number of late-model
cars at night and comparing the big digital readouts on their dash with my
tach.
