The only rubbing is on the air dam when I am in reverse at full lock and I give it a bit of acceleration. I need to trim or remove the air dam, but have not had time. Moreover, I have not had an opportunity to take it off road, but I have been told that there may be some rub on the flares at full flex. However, once i get to the ranch, I get in the ranger or on the 4-wheeler.

Have a great day.

You can save almost $40 a tire on the KM2's if you go to a 16" wheel.

That is the size and tire i am running. I have AEV beadlocks. Put them on before installing the lift (about 10 months on vehicle with stock susp). They didn't rub during normal day-to-day driving at all. Only when off-roading (flex) and one time heavily loaded it rubbed rear fenders when I hit a large bump and got full jounce in rear. No damage, just slight kiss.

I am happy with the size and tire tread (KM2). For how agressive the tread, it is not so loud. The power robbed is noticeable, but I can't imagine how bad 35's are without regearing. This is the largest I would persnally go without regearing.

The larger tires aren't significantly wider, so my contact patch to the ground is similar. The larger tires basically get you another inch or so of ground clearance, to me not worth the cost of regaring right now. Maybe later when these wear out, I'll have saved for gearing. But I'd rather do bumpers, winch, on board air, etc before.

I have the Full-Traction 4" long arm. It is plenty of lift for this size tire. The tires don't look excessively small for this lift. Is a good balance until I can re-gear and eventually go with 35's.
