Finally did it! Bought new tires to replace the stock contis on the QX56. After agonizing over Mich vs BFG and trying to get as close to stock as I could. I ordered a set of Toyo Proxy ST 305-60/18. Wow! the tires are 12 inches wide, (stock is 10 inches) so they just fit, with no modifications. They look really aggressive and great! Believe it or not the mileage on a long-trip just this weekend went up from 15 mph to 16 mph!
I put these tires on the wife's Murano as was really impressed so needless to say when I check out
www.powerdog.com and the the 305-60/18 was very close to stock I was excited. After being worried about the widith issue when we were done mounting them they are da bomb!
