TCowner,
You are correct, these are not the normal tires on here, they are Michelin XMCL Steel Belted Radials. The size is just a little bit larger. The metric number for the stock size is the 400/70R20. That would equal the 42X16X20 bias tire that came on it.
My tire size is 420/75R20. I went bigger, and would NOT do it again if I had the chance. It doesn't really hurt anything, but I can't really see where it has helped either. They are a little wider, 20mm. I had to change the front tires as well to keep my ratio correct. The stock size was a 27X8.50X15. I had to step up to a 28x8.50X15. Not really a big deal, but this little tractor runs out of power rather easily without load match on, so putting the bigger tire on there didn't help in that catagory. Especially at roading speed.
The tires are far superior in traction to the stock bias tires that came on it. They have a very flat foot print, so they distribute the load more evenly across the face of the tread. And they have enough load capacity in one tire, to carry the entire tractor and loader and still have about 1,200lbs more capacity. Obviously, these are overkill on here, but with steal belts, I am not worried about flats either. They are made for a tele-handler, but work good on here as well. The fronts are Titans.
