Trailer wheel and tire speed ratings are independent of the tire and wheel size, to a degree. Usually we will have multiple options for speed ratings in any given tire/wheel combination. If we do not note a speed rating you can presume it is 65-mph (speed rating code J or K). All 4.80 - 12 trailer wheel/tire combination products, as well as separate tires, are shown on the linked page.

You can click on your required weight load range to see the options.

For example, part # TTWAS12B4SMHP is a load range C tire on a silver mod wheel with 4-on-4 bolt pattern that is rated for 81-mph (speed rating M).

ALL special trailer tires, regardless of construction, size or load range rating, should ALWAYS be fully-inflated to the rated COLD psi pressure shown on the tire sidewall. It is never appropriate to under- or over-inflate a trailer tire for any reason. Some helpful articles on trailer wheel/tires are linked for your reference.
