I too own a 4110 with R4's. I do not know if all 4110's come with Titan brand tires and the non-accessory wheels, but that is what came on mine. I operate in Central Texas and use the 4110 for many purposes in all terrains. From trial and error, I operate the 4110 with the front "Trac Loader" tires at 30 psi (10 less psi than max) and the rear tires at 15 psi (20 less psi than max). Because my rear wheels are not setup for accessory wheel weights and wheel weights for such wheels are virtually non-existent, I opted for loading the rear tires with one gallon of Super Seal tire sealant, two gallons of Prestone low tox antifreeze and (with valve stem at top-center of tire) filled tire with water to "valve level" full (approx. 75%). According to charts, the 17.5L-24 rear tires filled as I did added approx. 465 pounds per rear tire. I cannot operate the rear tires at any higher psi or the tread wear is centralized. I cannot operate the front tires at a different psi because it squats during FEL work at a lower psi and does not get near the traction at a higher psi.
Due to our Central Texas climates and various terrains and the use of the 4110, I will not use a R1 tire. With the adequate weight and pressure, I believe you will find that the R4's are more than sufficient. I can operate in a lawn or a hay pasture with no sign that a tractor was even there. I can turn around operate the FEL under heavy conditions and plow/disk without any problems (whether the soil be black gumbo, sandy loam or rock). Again, I had to locate that optimal weight and pressure as discussed above, but aside from that, I am extremely pleased with these R4's (my first set). There will be times that you might get stuck as I have twice in the two years that I have owned the 4110. Both times were on the edge of a pond/tank that had recently dried up. Unfortunately, it was not that dry and the tractor sunk and slid to where the rear differential was hairs away from being bogged in the mud. R1 tires would not have made a difference. However, the R4 tires do require that the 4WD be engaged virtually 100% of the time during any operations. I thought that disengaging the 4WD would be better for fuel efficiency and wear and tear on the front axle. To the contrary, I read that utilizing 4WD is MORE fuel efficient. The 4WD allows for less wear and pull on the rear axles which counters the wear on the front axles when in 4WD. Thus, I operate the 4110 entirely in 4WD.
Hope this helps...from one Texan to another.
Albeit not entirely true, my grandfather used to joke and say that all a 4WD does is get you stuck deeper in the woods.
