The new Fun Country has wide lateral and offset tread grooves. The tread blocks have stone ejector ribs between them and thin siping that allows for tread block flex and increased traction in wet conditions. Not all tread blocks are the same size. They have had a computer-optimized pitch sequence built into the design for minimal noise production. The all-season, M S (mud and snow) rated tire handles temperatures from triple-digit heat to sub-zero temperatures while remaining pliable and giving traction where lesser tires spin and slide. This 305/70R16 Fun Country has a Load Range E, which means we saw very little sidewall flex under our Wrangler on level ground with only 12psi, but the tire flexed well and grabbed the rocks.
