I've decided to go with the Nitto Dune Grappler 285-55-17 based on the feedback I've received. My stock wheel size is 255-75-17. I know the Nitto Dune Grappler is a little lighter than the Cooper STT. The problem is that in the local area, nobody has them in stock. I've checked with AEV, ICON, RAMY and Zafco but it looks as if it isn't available. Please let me know if you know where I can find the Nitto Dune Grabler 285-55-17 in stock.
