Have you talked to your dealer?
Do you have R-4's or turfs now?
There likely will be a need to get different rims to fit the different tires, from what I've learned.
What is the background for the request for changing?
I like the R-4's over the Ag tires I used to have, mainly because they are heavier ply (plus the wider width, the lower profile, and less tracks in the lawn).
True that the traction isn't as good, but then in snow and if in mud, I put on the tire chains and get better traction than with the Ag's without chains.
Wish you luck finding the Ag's with rims, as the age of the 4410 might work against you. Things seem to get settled down after a few years of age. But still hope you find the Ag's .
Thanks for the replies, but I have already bought the set JimmyD had posted. Nice guy, good meeting him. I spent last weekend pulling firewood out of the woods, and they worked awesome.
