Interesting. Not nearly as much difference between the R1 and R4 types with larger tires. I wonder what the functional difference is as the tread design is so similar and the R1 tread really isn't much deeper at all.
I couldn't say exactly. I have wondered something similar at times before because the R1 lugs just aren't that deep. To me, they seem more aggressive than the Kubota R1s.
In the first post of another TBN thread is a picture of a BX2660 with R1s. Those look different than the ones on the MF. I had to even do a double-take to make sure those weren't R4s. The end of the lugs are squared off similar to an R4. It looks more like an aggressive R4 than a true R1 (like an R4 with narrow lugs).
