I run 7.50 R16s on my 16" split rims on my 85 Landcruiser. Sure, they are not great over 65, but they do 65 no problem. I live in the mountains where we have nasty snow and ice the Goodyear Workhorse are right at home. I'll be going to a summer tire when it warms up though because they are wearing a bit faster than I like.
