Figure I'd bump this thread instead of creating a new one. Seems that rv.net is the only place to find any detailed discussion of 19.5" wheels/tires for TC applications. Go figure!
I'll cut right to the chase. Is this what I want for my F-350 SRW?
Vision 81A (or 81b, apparently?) 4.25 backspace, 8x170. There are a ton of other model options there, and if anyone has a quick comment on the relevant considerations, that would be much appreciated. https://www.visionwheel.com/wheel/867/VisionHDTruck/Trailer/81A%20Heavy%20Hauler?finishID=12
For drive tires: https://www.michelintruck.com/tires-and-retreads/selector/info/xds2-19.5 Pretty much decided there.
For steering tires, I really want snowflakes (lots of mountain/winter driving). Doesn't look like Michelin does that. Anyone else?
