Overall width depends on tire type and how wide you have them set.
Minimum width w/ R1 62 in
Maximum width w/ R1 91.1 in
Minimum width w/ R3 71.5 in
Maximum width w/ R3 74.4 in
Minimum width w/ R4 71.5 in
Maximum width w/ R4 92.6 in
I think there's also another ag tire with a different profile available now discussed by John Miller in another thread. These are the 4700 specs but I believe that they are the same for the the 4710. There'll be a slight variation with tire pressure and attachment load on the 3PH. R1s you could fit with a couple of wheel setups. Pretty tight for the R3s and R4s in their narrowest configurations.
