what is a good guideline to tell you when it is time to get new rear drive tires on a tractor? my rear tires ( 18.4/34 ) on my ford 7710 are showing some wear ( i use this tractor to pull a disc or f.c. ). wondered if there are any tread measurements to give someone a good idea when to replace-especially if it comes to the point you might be losing traction in the field.
