Michelin has a tire called Symmetry in 225/70R16 that has a 107T rating. I've been looking back and forth at this one for a while this afternoon, as well as looking at others too. The Michelin site says the tire is intended for large passenger cars like Ford Crown Victoria. Seems strange to me that this "car" tire has higher weight rating than the tires they show in this size for light trucks.
Keep in mind the P tire's load rating shall be reduced by dividing by 1.10 before calculating the sum when used on a trailer.
Example is a 107T rating is now at 1950 lbs capacity. Many P tire have just one sidewall ply so I wouldn't be concerned of a difference in load capacity.
The LT225/75-16 E has a 115 load rating.
I also did check on the BF Goodrich All-Terrain T/A in the LT225/70R16 size but that load range C tire is only rated as 102R, 1874 lbs per tire.
A all terrain (AT) type tread with those large lugs and voids isn't the best choice for a tire on a highway trailer. Those larger lugs/voids can create tread roll/trailer tracking issues.
BFG's better choice is the BFG Commercial T/A 2 LT tire which they recommend for commercial use.
Look at the Firestone Transforce HT.
also the Goodyear Wrangler HT...
also the Cooper HT3 AS...
The AS or HT tires are a all season type of tread and make a better tire choice on your trailer.
