Many people on this forum have been disapointed in the traction provided by R4 tires. They are ok on dry firm ground but severely limited in loose ground, mud or snow. In these conditions an equal weight 2wd with R1's will almost always perform equal to or better than a 4wd with R4's when performing drawbar work. In many cases the 4wd is able to offset the traction deficiencies of R4 tires, but if you really need traction to get your job done then a 4wd with R1's is what you will want. If you try to use the same machine for cutting your lawn and doing feild work you will be making some sacrifices in either lawn damage or traction, that is the cost of compromise that is associated with the R4 tire. Anyone who thinks R4 tires can match the off-road traction of R1's is very badly misguided.

I don't think anybody here is saying that. I think what they're saying is that R-4's on a 4x4 can out-traction R-1's on a 4x2 in a lot more situations.
I do think a 4x2 w/ R-1's could do as well or maybe better than a 4x4 with R-4's pulling a bottom plow on loose ground because the plow puts a lot of traction on the rear axle and helps to lessen the effectiveness of the front axle on a 4x4.
My R-4 equipped 4x4's are by no means severly limited in mud. I work in mud constantly and having 4x4 makes all the difference in the world. Plowing snow seems to be a piece of cake, too. Otherwise the 4x4 backhoe with R-4's and a snowpusher box wouldn't be the equipment of choice for big time snow removal.
You can always fill the tires on the R-4's or add wheel weights if you want more traction.
Looking at the advantages of R-4's, you get better tire wear, less damage on grass, pavement, concrete, etc.
Unless pulling a bottom plow is all you do, I'd still take the 4x4 over the 4x2.
Those are about it in a nutshell. No way I can see to compare 4x4 vs 4x2 for
overall traction in the tire combination youve stated. R-4s can often, wheel for wheel, give better traction on
unpackable material like gravel or sand and some snows, and also on hardpack, but in the majority of real world farming situations the R-1s win easily on a wheel for wheel traction basis. As stated in quotes the 4x2 R1 will need most of its weight on the rears and fairly flat land to compete. The closest you can get to "overall" is 4x4 R1s.
