1200 Field Cultivator tire size.

I had a 24 footer and it had 9.5L on it. They worked good so I assume they were the right size. ---all 4 matched and were implement rib style.

My 1973 AC 1200 Field Cultivator sales brochures says 14” wheels less tires?? So dealership supplied implement tires?
My 1981 AC 1200 FC brochure says gauge wheels as follows; “On the manual fold models, these wheels are light weight for easy folding. With the hydraulic fold, larger wheels are used to provide increased flotation on soft soils and positive depth control in hard, tough soils. An 8”x14” rim uses a 11”x14” flotation tire.”

Guessing for a lightweight 4”-14” rim would use a 5.9”-14” tire. And maybe a 5”x14” rim would use a 7.5”-14” tire? A 6ply implement tire should suffice. What size are your car tire rims that were mounted your 1200?

Back in the day implement dealers recycled alot of car tires putting them on implements, but I am sure as things got bigger, heavier and required special tires, and people had a few bad experiences with used car tires more stuff got sold with new implement tires.

What size are your car tire rims that were mounted your 1200?   I don't know what size the car tires were.  They were in such poor shape I had to measure the rim to know what diameter tires to get.    These cultivators being shipped without tires explains why practically every cultivator that I have seen has car tires on it!

I think the rim should be stamped with its dimensions somewhere

I have a 1300 field cultivator.  Just the main frame.  Wings long gone before I acquired it.  Anyway, I have 10.00-15SL 8 ply tires on it.  I had to replace the ones on it when I acquired it, and as I recall these are a little larger, but don't recall the size of the old ones.

I'll have to look to be sure but I think my 18-1/2 foot 1200 has all 14"...... for sure the wings are 14" and they are hydraulic. We bought it in the mid 1980's and it wasn't very old then but it had car tires on it at the time.
