I replaced my factory bias ply 205/75/15 load C (even lesser known china brand) with same size Towmax STR II Load range D radials. They came with the new L speed rating.
They don't heat up near as much as the bias ply's did after a highway run. Trailer pulls better with them. I have about 600 miles on them, still new looking.
