If you are going to use chains with Ag tires, don't bother with the 'standard' chains. You will need ones like these:
They will not drop down between the lugs and become useless.
According to their 'search' those are available in 23x8.50-12 tires. I just wish they had them for 26x12-12, but alas, they don't see to have them for that size
Also, for filling your tires, Rim Guard is far and away the best. NOTHING beats it for filling tires It's roughly 3 lbs/gal heavier than any water based solution. Not to mention that it's non-corrosive, non-toxic, and biodegradable if it does happen to spill.
Many thanks, i ran into that problem with the Hesston for skidding timber, grampa switched to forestry diamond pattern studded chains and it was almost unstoppable in the woods. See a similar studded type for ATV tires but only see them for the 23 x 10 -11 tires.
I forgot about the rimguard, serching the net it seems the 23 x 8.50-12 tires would need 7 gallons each.
The old rims on the Ford 1200 rotted out due to the calcium chloride.
