No Mud here in Las Vegas we have not had appreciable rain for the last 6 months. Also I went with 9 inch wide all corners to keep rear weight down. I also finally went riding last week end and just love them in the rocks and washes i ride out here... I did not feel any change in acceleration or loss of power. Real Happy with my ripsaws after first week end....Unless you are a deep mudder you will like them I'm sure. Main knock on them is they are on the heavy side.. but extremely durable and stable tire with the flat footprint. Look tough.
