So I got a 2006 Quad cab, 4x4, auto, with a Cummins. I was on the fence about a manual, but I found this auto one and it drove well. Much better than others I have driven and had a lot of maintenance done by the Dodge dealer. New ball joints, wheel bearings, 2008 steering, and engine maintenance. Anyway, it has Toyo Open Country Mud tires that seemed fairly quiet when I test drove it, but on the drive home after 30 minutes on the highway they are annoying me. They seemed fine til about 55-60 and then the hum turns into an annoying vibration of sorts. I bought the truck with the assumption I will most likely swap them out and otherwise the truck drives straight and doesn't pull. I am sure it is not the truck itself and it is not a balance issue. They are almost brand new and are 35/12.50x17 on stock rims. The suspension is stock and they fit OK, but obviously rub on the control arms at full lock. I assume they won't get better with age? Any suggestions on a more friendly highway type tire and size? I was thinking 315/70x17 Yokohama Geolander A/T-S. Also is a Load Range D enough or do I need an E?
Thanks in advance.
