I don't doubt you've seen something. From five- or seven o'clock it
could be dust kicked up by wing-mounted jet intakes that might appear to
come from the main gear. I've watched a lot of large and heavy jet
departures from the number one position and I don't remember seeing
anything that could be interpreted as smoke from the tires under those
circumstances.

Curious, indeed.

What began as a question to ascertain the frequency of aircraft landing
from above another has turned (due to my poor verbiage, possibly) to
how smoke emerged from the 747's wheels on takeoff

Is it common to see planes commencing their takeoff roll before a
just-landed aircraft has fully turned off into the exit? That clearly
happened in the incident I wrote about too...
