My 2009 Dodge Ram 2500HD with a Hemi will be needing new tires soon.  I've already got 37,000 on the factory BF Goodrich  All Terrian tires.  Size is 265/70/R17.  Load Range E.  I love the way these tires look but know nothing about tires.  What does NAT recommend.  This is my daily driver on gravel roads.  Ocassionally a skid steer, seed caddy, 1,300 gallon water tank, and NH3 tanks.  Would sure like something that softens the ride some.  I may also install some Sulastic Rubber Springs.  Thoughts?  (We had a good harvest but I told the better half I would buy another pickup yet)
