All great reference info, appreciate you capturing the Jeep list in one place. That said and not trying to be an a-hole, which do you list here, wms-wms or tread? Just asking because you weren't exactly clear and the CJ widths look less than the wms-wms numbers I've been looking at recently as I plan out a '46 CJ2a resto-mod.

Thanks for clarifying,
Ty
