Just installed some system3 sb4 beadlock wheels and 28×10×14 carnivores on my 2012 t4. The wheels are 4+3, and the tires fit good. I also bought a brute force 2 lift, but havent installed it yet. I have the floor board recall and the front tires only rub at full left turn. I will probably still put the lift on, but if you wanted to run this set up without a lift you could. I ripped some hot laps around the yard and I dont notice any power difference with the bigger tires.
