I have a commander Maxx. I have 27/9 on the front and 27/11s on the rear. I put a 3 inch lift kit on and now want to get larger tires. When purchasing larger tires do I still keep the front ones thinner than the rear or all the same size? what is a good recommendation on a set of 4 tires? I would like to be at least 30 inches. Thank You.
