2” lift kit with 275 50 20 requires no mods. The 60 20 is feasible but will require mods. I am leaning towards the 50 20 setup as soon as I get done rebuilding my engine. What setup do you currently have?
Currently running 255 55 20 duratracs which replaced 275 55 20 road tyres. I remoulded the arch around the fuel filler cap to get the 275 55 20 to fit. Unfortunately the duratracs aren't great in heavy mud / clay as they struggle to self clean. Have found more aggressive tyres in 275 60 20 but want to understand what mods I will need to make.
Yea the arch and inner plastic would need to be modded to make the 60 20 fit. And Just couple things to relocate to avoid rubbing. Few threads on here you can look up. The folks at johnson rods will be a lot resourceful to you. Contact them.
