I presently have good but mismatched 8.3s on my Lo-Boy cub. My first A has a good matched set of Safemark 9.5s.
I have been on the look out for a deal on a new or newer used set of 11.2 or 12.4s for that A #1 (first one with the carryall).
If I score a larger set for that tractor, A #2 can get the 9.5s and the Lo-Boy can get the new 8.3 set, Incidentally they are Firestone field&road so though small. they should wear extremely well. They probably cost a pretty penny too.
Probably more than the $550 I spent for the whole tractor.
It always seems to be hard to find any used set of tractor tires that arn't totally wiped out.
They are probably the biggest expense to consider into the budget when picking up a used tractor.
Order of priority, how does it run? What do the tires look like?
All the other parts that you may have to chase down are smaller in comparison.
A new set of rubber around here is about $800.
For that price I should be able to drive it to work.
