I have a 2wd jd 1070 with 44x18-20 turfs. It is good for finish mowing (notice good, not great- it will spin on grass backing up a hill sometimes) but absolutely terrible in anything else. no chains and no fill so snow plowing with a rear blade is a real chore.
I bought a fel last year for it and am considering purchasing a box blade for occasional use. I also picked up a set of rims and was deciding on r-1's or r-4's to use for an extra set for the box blade and hopefully very seldom use of a 2-bottom. Reading this has made up my mind to go with the r-1's since I have the turfs to put on most of the time. I really don't want to fill them, just because of the switching back and forth.
One question I do still have is 6 ply, 8 ply, or possibly 10? I'm thinking 8. My tractor is 39hp (35pto) weighs right around 3000lbs with no implement. 3pt will lift 2000lbs.
If you plan on doing much FEL work with HEAVY loads figure on using R4s at least on the front.
Even if you put R1s on the rear the R4s on the front would be better for not sinking when carrying a load and the load rating of R1s pretty much dictates R4s for loader work anyway.
Since yours is 2WD you don't have to figure rolling circumference ratios (-:
For just about exactly $300 a set of Peerless DUO chains on those turfs would make a REAL difference for snow removal, even get you around on ice.
I would probably bet my megamillions ticket they would beat out R1s, especially given their WIDTH.

At something like 55 lbs lbs each the free shipping makes it a REALLY good deal, the other big web order tractor chain place is little/no cheaper, charges shipping and admits to selling Chinese imported chain - nothing WRONG with that if they were way cheaper, but I liked the idea of Peerless chains - they drop shipped mine directly from Peerless.
BTW, the set for 17.5L24 R4s is the same width and has one more DUO cross assembly in it, I bought that set since I have 44x18x20 turfs as well as the R4s for my little'est tractor.
The 44x18x20 take set number 1077010
the 17.5L24 take set number is 1077610, basic difference is 6 cross assemblies vs 5 for the turf set.
My 17.5L24s are loaded with RimGuard, 900 or so pounds each.
Not too bad to swap, I use an engine crane with a strap, I just NEED a couple of feet of smooth clean concrete walk path to roll the crane out/in.
The turfs are easy to roll around by hand or I would need two engine cranes..
