Not sure why he ruled out the wranglers, maybe cost reasons. I looked on the Nokian website and the WR G2 looks good. However I could not see the 235/60/18 listed (strange as sure other posts have said this size exists):

One thing though looking at the picture they do not appear to have as good rim protection as the rest, but then this could just be because the tyre shown is not the correct size?
Looking back at the Wranglers, the goodyear site seems to lead these more to offroad, so maybe for me these are not needed.
