LFGT Rear Wheel Size?

[PhanDad]

In mounting wheel weights on my Homelite and GTH-L I noticed the wheels are different. What's the correct wheel size for these tractors? Both my A/C Homelite T-12 and Simplicity "16"GTH-L have 23x10.50-12 tires. The A/C Homelite T-10 I parted out had 23x8.50-12 tires. The Homelite T-12 rim is about 9" wide; the 16GTH-L and Homelite T-10 rims are about 8" wide. The offsets are also different Did someone put a too small rim on the 16GTH-L? Or has Simplicity switched to smaller wheels on newer models? Might the difference be related to the switch to Sunstrand from Vickers? I was thinking of mounting a set of Ags on the T-10 rims and thought I would have to get 8.50's. But since the 16GTH-L has the smaller wheels, I guess 10.50's will fit. Thoughts?

Different models Landlord, Broadmoor, Sovereign etc. had different width wheels some 7" some 8" and I believe 9" with different off sets (back spacing). I have 7 tractors in the garage all with 23 x 10.50 x 12 tires but 3 different wheel widths and back spacing.
