Nonsense... tractor tires are pumped up hard as rocks, in fact they
may as well be rocks because they're filled with lime to add weight
for traction. The only suspension on modern tractors is their
pneumatically dampened seat suspension, but doesn't really help much
except on very level smooth ground like a paved roadway, in the field
it bottoms out with every little bump in the ground, often quite
jarringly.

Perhaps you're talking about those garden "tractors" one sees at the
big box hardware stores.... those are NOT tractors, those are riding
lawnmowers... some will soften their tire pressure to achieve a wider
tread print to minimize ruts in soft lawns (those toys have pretty
narrow tires), but then the tire life will be significantly shortened
and fuel consumption significantly increased, not to mention adding
significantly more strain on the engine.
