The tire size you referenced, A78-13, corresponds to the metric tire size 175/60-13 and this size tire will fit 13-inch diameter rims of 4-1/2-, 5- and 5-1/2-inch widths. The linked article includes a cross-reference. Tires in this size are available in three load ranges:
Load Range B: 1,100 lbs at 35 psi
Load Range C: 1,360 lbs at 50 psi
Load Range D: 1,610 lbs at 65 psi
We offer tires on their own and also mounted on a wheel. The link provided will show you all options for both tires-only and tires-with-wheels.
You can use the filters at the left-hand side of the page to select a tire or tire-with-wheel, tire type, bolt pattern, load range and wheel type. For example, part # AM31985 from Kenda is a Load Range D tire on a white steel wheel with a 5-on-4-1/2-inch bolt pattern
