Keep in mind that the R4, as used on CUT's, are a "compromise" tire that give up a lot of traction in mud or snow. This causes many folks who use them for ground engaging work and such, considerable disappopintment. They are better on lawns than R1's but still cause significantly more damage than turfs due to the bar tread pattern. If you are limited to one tractor and one set of tires and need to do some lawn work and some ground engaging work, then the R4 is the tire for you. If you are a no-compromise type and can swing an extra tractor or an extra set of tires, then turfs and R1's would be best. I have (2) tractors with turfs for on my lawn and (4) with R1's for off. You would never catch me with R4's unless I got into the construction business. I did a little of that once and R4's were best there for sure and they worked great on my tractor-loader-backhoe.
