Max tire size for 52" bob-cat fastcat pro "F" series

[psjoe]

I posted this in the homeowner forum but did not get a respose so I am trying ere. What is the max tire size for 52" bob-cat fastcat pro "F" series?

The bob-cat has the zt-3100 transaxles and 20x10-10 tires. Does anyone know if I can fit the carlisle AT101 21x11-10 tires on this machine?

In addition, does anyone have a tire recommendation to help with traction?

Thanks
