The Michelin XPS Rib is a commercial grade all steel ply carcass tire and very expensive.
The BFG Commercial T/A 2 is a poly carcass tire. I've ran them for years on my heavier trailers.
I would choose the all steel ply carcass tire over the poly tire for carrying weight.
Another all steel ply carcass commercial grade LT class tire is the Bridgestone R-238 which replaces the older R-250. Their priced well under the XPS Ribs.
Check all of them for your size.
