I just got done 4 days straight of driving over logs and stumps with R1’s carry logs and brush in my grapple.
No sidewall damage, no flats.
They make heavier R1’s for that type of work you know?

Heres actual log skidder tractor photos
These look a heck of a lot more like R-1s than R-4s

R-4s are great for use on pavement and compacted soils. R-1 s will do anything R-4s will except last as long on hard surfaces.
Conversely, R-4s will not do nearly as many tasks as well as R-1s.
For the average small tractor and hobbyist not going into deep mud or deep snow, R-4s are fine.
However, I can’t understand why anyone would want a tractor, being used for it’s true intent, which is
traction, not having R-1’s. They enhance the tractors traction and utilize more of its pulling power. They sort of give you more drawbar HP which is what you want for pulling or pushing things
