Hello Manuel, thanks for reaching out. We do carry the ST205/75R15 tires, but nothing with a 16 py rating. The highest ply rating we have would be a load range D which is 8 ply rated.
For example, the Karrier ST205/75R15 KR03 Radial Trailer Tire - Load Range D # AM10245 has an 8 ply rating. The weight rating is 2,200 lbs at 65 PSI.
Would something like this work for you?

Hey Manuel, did the Karrier ST205/75R15 tire end up being a good match for your trailer? It’d be great to hear how the load range D option handled your 10,000‑lb setup. Your update could make it easier for others choosing between ply ratings.
