Cheap and tractor tire do not belong in the same sentence. I just
replaced the pair on my TO-20 with new Titan 12.4 X 28 ags. $483.00 plus
shipping! Added Beet Juice ballast (I HATE CaCl,).

$500 for a pair is an OK price. I found a guy that will do one with no
fluid - $185 tire, $30 tube, $40 labor. Then, of course, the governor will
get his cut.
