Probably the best option would be to get wheel weights if they're available for the R4s. I had thought about getting R4s when I was shopping for my m7040 but since I would have had to change the wheel size and reprogram the speedometer I had second thoughts. I was a little bit concerned about the gear ratios when using 4WD if I had changed the wheels too. When my dealer told me that the CI disks weren't available for the size of wheels the R4 tires would fit I decided against it. With your use for the M7040 YOU could always look into getting a 3rd party subframe mounted backhoe for it. Now that would be pretty cool looking. I doubt if it would work though.
