Correction:
I had my logs out going over numbers for insurance application and I must make a correction to my earlier statement. I did rotate my tires on the rims on an annual inspection when I had the wheels off to grease bearings. At that time the tires had 146 flight hours since new and showed a very slight side to side uneven wear. I attribute that to camber issue and not toe-in / toe-out alignment. I would estimate I'll get at least another 100 hours of flight time before replacement. The number of takeoffs and landings on these tires is high as most of my flights are in the local area and not long cross countries. Larry Flesner
