The three radial special trailer tires we offer in size ST235/85R16 are shown on the linked page. These are Load range G tire # TTWPRG235R16 from Taskmaster, Load Range F tire # AM10501 and Load Range E tire # AM10295 from Kenda.

Taskmaster # TTWPRG235R16 (ply rating 14) is rated for up to 81-mph, an M speed rating.
Kenda # AM10501 (ply rating 12) also carries an M speed rating.
Kenda # AM10295 (ply rating 10) is rated for 62-mph, a J rating.

A trailer tire's worst enemy is heat, and excessive heat can be avoided by ensuring you do not overload a tire beyond its rated weight capacity and that you stay within its speed rating. Always inflate all trailer tires to the full cold psi pressure rating noted on the tire sidewall; it is never appropriate to under- or over-inflate a trailer tire for any reason.
