Tires Kubota GT3

[W5ray]

Hi, new tractor for me and it came with agricultural tyres on it - thinking of changing to the "R" style of tyre as the current ones will cut up the paddock when it is wet. Have some woods as well and want to use the tractor in here for logging so probably a no to grass tyres.
Question:
How are tractor tyres and wheel sizes measured?
What about wheel nut spacings? are these standard or specific to each tractor make / tractor size.....

Don't read Japanese but playing with the PTO controls found a bonus in that the PTO can run clockwise or anticlockwise......
All my current attachments are clockwise so what is anticlockwise? Just curious....

Thanks

That's an old tractor, but they can still work very well.
Here is a link to your tractor data. Specifically OEM tire size is indicated.
