I also purchased a set of 5 Michelin LT 255 170 R17 E1 121R W MICHELIN LTX M/S2 ORWL
I like them very well. They give you a bit more traction. One down side, sorta...
The tread is wide. The groves are wide enough to pick up gravel and will throw it once you hit the highway. Scares the heck out of the fir kid and the DW.
