Thanks Triple. I wish the 7040 had tire options like the 8540, but according to the "build your own" section on the Kubota website, it doesn't. It will only let you select from cast or stamped rear wheels. I'd love to order it with 11.2 or 12.4 fronts with the highest ply I could get. I'm concerned about loader work and working in the woods. I could go with R4's, but I really don't want to because of the shortness and there for loss of ground clearance. Plus R1's just look better on the M's I think.
I went by my closest dealer on the way home to look for the ply rating on the 7040 he had on the lot, but it was gone.... I would have gone in and ask, but I don't plan on buying from them and figured it wouldn't be right.
