The Sailun S637 in 235/85/16 is the way to go nowadays if you have 110 psi wheels. If not, go to www.tredittire.com
they have a large variety of wheels at FAR better pricing than any I've found. They have Sailun tires too, but are cheaper at NTB than there. Also, they carry the 17.5" wheels and tire combos that a lot of newer rigs are coming with.
