Insane Mud Tire

Ran these on a dodge 2500 with a cummins. Comparable mileage to most radial mud tires on market. Best traction ive experience in a mud tire for wet and/or icy roads. Tires were out of round mid way through its life made for a bumpy ride. First 15K was smooth as glass though. Very loud comparable to swamper bias ply tires without the rough ride.

How well would these tires do on the streets? Also would they look mean on a 10 inch wide rim? Which would be better the Toyo Mt or these for lasting quality and miles?

Hello Big Perm, Thank you for asking. The Nitto 37x13.50R18LT, Mud Grappler would look perfect on a 10" wide wheel. On a personal level I would rather go with the Toyo's. Don't get me wrong, the Mud Grapplers are beefy looking and a good tire but when it comes to millage life I think the Toyo's has it beat.
