Tire Selection John Deere 1050 Tire sizes?

[bburke80]

Can anyone tell me the tire/wheel size combos for a John Deere 1050 4x4 Tractor?

I have AG tires on it now but I want to get Turf or R4 for it.

Tractor Data shows the tires as:
Ag front: 6.00-16
Ag rear: 13.6-28

I'm pretty sure the fronts that are on it are 8" though...
