Thanks for the info ASA.
It makes sense that I'm doing the same thing as you with the wheels as you are partly to blame for me getting a Scout in the first place

I read through your posts when you bought yours and your exploits after you got it. Even looked at the YouTube vids. I chucked at your description of your Maule when you first got it but it seems like it's grown on you.
I do have the new axles from ACA. Not anything brilliant on my part though. Like you, I had no idea the OEM wheels were 8 1/2". There are plenty of pictures of Scouts with Bushwheels on the OEM wheels so I thought they were fine but that doesn't appear to be the case. The STC (at least the one I have) doesn't spell out 6" wide wheels, just the heavy duty brakes. However, I don't want to trash these tires so I'm getting the new wheels. It would be nice if they were still $1900 but that ship has not only sailed, it's made it to port and is on the way back again.
Bigrenna has been very helpful (Thanks Greg!). He's suggesting Aero Classics 8.50 4 ply for the winter too. I currently have 26 GYs for when the 31s aren't on it but I think he's correct, a smaller, lighter tire makes sense when the 31s aren't necessary.
Thanks to both of you for the info.
