It looks like the Sahara is on larger wheels than the rubicon on Mopar beadlocks, but that could be an illusion of the lower fenders. Here is a pic of mine with 315/70 KO2's with the same wheel.
Additionally, both of these jeeps have the Mopar lift kit installed and mine is factory. Look at the difference in clearance between the tires and fender. Red is on 37's, blue is either a small 37 or a 35x12.50.
