Tires Loaded tires with heavy implement question

[Smallplot]

Have a TYM T-603 @ 60hp and needing to fill rear tires. Will use Rimguard for rear tires if we can safely load the tires. With a heavy load on 3-point (talking around 3000 #) would there be any issues with loading the tires? They squat some with that heavy of a load and just looking for experience. Our larger tractors have loaded tires but there is no squatting issues with them.

Squatting of tyres under load usually means that there will be excessive flexing of the side walls under loaded running, are pressures right for the load application?? And excess side wall flexing can lead to premature tyre failure??

You usually raise tyre pressure to allow heavier loads to be carried.

Proper tire inflation based on axle loading is necessary whether or not the tires contain liquid ballast. Some sidewall deflection is desireable, too much is not.

Deflection is such a better word than squat. Guess it sounded like the tires went half flat the way I was describing them, which they do not.

Squat is a fine term. ... esp to describe an active effect under a pulling load. Ballast will not affect axle loading, and will reduce squat due to causing a higher compresion ratio in the tires. With a heavy implement and loaded tires your tractor will be a force to be reconed with. It will bite the ground and leave tracks. It will also be more stable.

If your tractor has 16.9 x 24 tires, the max load per rear tire is 3420 lb at 18 psi for 6 ply and 4400 lb at 28 psi for 10 ply. The tire standards say the weight of liquid ballast must be included in the load. If it has the smaller 14.9 x 28 deduct 200 pounds per tire. Standard weight of the tractor is 5380 pounds so as a guess 1500 per rear and 1200 per front. If you have the 10 ply tires it should be pretty good but 6 plys might have a problem with a lot of time at max load tires plus load on the 3 point. I see the max lift capacity is 2528 at 24 inches behind the hitch so it will probably be hard to overload.
