What does 750R16 equal in todays metric tire size?

I have an older one ton with 5 good 750R16 Goodyear Wrangler AT's on it, but I need one more. They still make goodyear wrangler AT's but now they are in metric sizes like 235/85R16 etc..I asked the guy at the tire shop and he did not know the cross reference, which seemed lame to me.
