I'm new to off-road tires, my spirited driving would always wear out sports car tires so often this was never an issue 
I'm planning a long road trip, the tire tread looks like it has a bit of life left, but just curious if these cracks (2 photos below) are a safety issue on the highway, not so worried about off-road trails but don't want a blowout at 80+. The DOT code ends in 1916 so they'll be 5 years old in May. Thanks!
