Looking at throwing some new shoes on the truck within the next week or two. I have the cooper discoverer atp's on right now @ 275/65/20. I like them alot and they have lasted me a long time. But I've been reading about the Nitto Ridge Grapplers and the Duratracs. I have been trying to find somewhere that compares the 3 but haven't found it yet. Does anyone have experience between the differences of at least two of these? Trying to get a comparison on ride/noice/traction other than the salesman at the tire shop. Thanks!
