Tires Finding taller tires NH tn75da

[skidsteer.ca]

Our 75 hp new holland has 10.5 by 20 front tires and 19.5 by 24 rears.
I'd like to find some other tires sizes that would fit my wheels. There is clearance for up to 6" more radius on the rear. Does anyone know a good source of specs online to see what my options are.
Tractor seems to have low enough gearing that that should not be a issue.
Thanks

My TN75D has the largest tires New Holland offers. The rears are 16.9 x 30 R1's. I'm not near the machine so I don't know the fronts. The rims for these are clearly different than the ones you have.

Let me know when get a chance.
Is there generally only one tire size for each rim.
We would sure like to go taller, don't imagine there is any place that will take good used stuff on trade?

Thanks
