They don't have tyres as in rubber type tyres Col, they are large saws, the band wheels are cast iron/steel and crowned, the bands were tensioned to a very high tension, my old Stenner used a screw jack, my old Forrestor used a hydraulic jack, these jacks were built in as part of the headrig.
The Forrestor was an all fabricated bandsaw, even the band wheels were fabricated from welded components.
The Stenner headrig was an all cast iron jobbie including the band wheels.
I couldn't say for sure weather either of the above were fitted with heat shrunk steel tyres, it's not something I would have noticed, the band wheels would do a serious amount of mileage before needing a re crown, we never had any re crowned, the last I heard Stenner would still re crown wheels off their really old saws.
The bands would be rolled and tensioned when sent for sharpening, the Forrestor ran a 4" band but you could keep sharpening that down to about 2.75" and it would still just about hang on to the bandwheels at the correct tracking.
The Stenner ran a 5" band and we could take that down to about 3.5" although to be fair they never cut the same when they are sharpened right down as the blades start to wander somewhat due to age and crack repairs then eventually crack beyond repair.
Typical run time for a fresh sharpened band was 4hrs max then send away for sharpening.
