I had a friend run 30x10-14 Blackwater Evo's on 0 offset wheels (like putting wheel spacers on the stock wheels) with a 2" lift and slightly cranked shocks (gaining a little more lift). He had to remove the recall fender pans/steel liners (recall item on pre-'16 models but '16 and newer came from factory that way), AND the Blackwaters are known to run short so technically it was more of a 29" tire. For example, the 27" Blackwaters on my dad's machine are the exact same size as the factory 26" Bighorns that came on my T4.
I ran 28x10-14 Intimators on mine with the Highlifter lift kit and 2" spacers with slightly de-cranked shocks (lower lift of probably 1.5") and the fronts would slightly rub when turned at full lock. That was with no recall fender pans. Those tires are right at 2" taller than the factory 26" Bighorns. I then installed a set of 30" tires (again, these were a true 2" taller than the 28's) and they rubbed really bad. Even adjusting the lift up to around 3" total they rubbed both front and rear bad....the fronts rubbed so bad that there was no way I could take it on the trail until installing the offset arms.
