New Direction, plenty of heavy operators care how many landings they get out of a tyre! From memory the figure was about 40 or was it 70? I can't remember.
Undamaged heavy tyres are retreaded up to about Seven times according to my memory - ultrasonically tested each time of course.
I bow to Leady and Mach as my knowledge of this subject is a bit rusty these days. In my day the drivers would be concerned to have good rubber if they were heading for a few wet runway landings. Dry weather ops? Not so much.
