I used to run 235/86LT16 Hankook RF03's (all-terrain), but went to RT01's (mud/obnoxious stuff tread). I get them mostly because that'
s what we stock where I work, and they seem to be a pretty good tire. The RF03's are a great all-purpose tire, and great in snow, but we had a set of RT01's on the rack one day when I needed new rubber, so I got them. They're a little noisier, but will hold better in mud. Haven't had the chance to try them in snow yet.
As far as heavy truck tires, I have a set of nearly new Hankook AL01 22.5 steer tires. (Steer rubber ain't cheap.
) The drive tires are pretty much mix and match, mostly whatever was on the wheels when I bought them to replace the 10.00-20 rubber that was on it.
