REFLECTOR: Tire (OZ...= tyre) wear

[Ron Brown]

I have a copy of the Aviation Consumer file (PDF) that I can email (1.8mb) 
for anyone that wants a copy.

The key is that the tires are close to the same diameter, however the tread 
profile is important in that the Condors are rounded, the retread and 
Goodyear's are more squared off.  This squared off edge will hang in the 
gear well if you built using the Condors as a pattern and cut it too close.

Re how frequently to adjust the toe in, just measure the tread depths and 
watch what is being worn off every 50 hours or so.  Then adjust shims as 
needed to even the wear out.  Rotating the tires is a necessary procedure on 
the RV's as well.
