Absent moderate to heavy loader use on a normal basis, lamarbur is correct in that loading the tires will not be advantagous. However, we load all of our rear tires, including our 4110 with R4's. Let me backup and say that we used the 4110 for about a year prior to loading just to see how it would react. The tractor performed well 40% of the time, but loading was needed as the rear would get light and either bounce or completely raise one or both sides of tires from ground. The main use of the 4110 is forage production (moving, storing, loading large and small round/square bales), land preparation (disking, box blading, fencing, post hole digging, grading, spraying) and feeding the livestock.
The Mahindra OEM wheels for the 4110 do not have accessory holes for mounting wheel weights and other accessories. There are companies that manufacture different styles of wheel weights that mount differently, but the weight needed for a true rear
ballast on the 4110 was too heavy for them. The option of a rear ballast box or other implement occupying the 3-point was not an alternative for us as we either need to be free to attach whatever implement is needed (regardless of its weight) or attach nothing when moving, storing and loading forage as an implement requires that much more space when navigating. Another thing, the 4110 manual (p51) refers to track adjustment where you can increase/decrease the rear tire width, but the 4110 OEM wheels do no support it.
