Hello Jason.

They don't have instructions for their wheels and tires. The torque specs for the Karrier ST175/80R13 Radial Trailer Tire with 13" Aluminum Wheel - 5 on 4-1/2 - Load Range D # AM31998 is 75-85 ft. lb for 1/2"-20, I have attached a chart to reference for the torque specs. You want to keep the tire inflated at 65 psi. It is important with trailer tires to keep them inflated to the max psi to prevent a blow out.

Here is a link to the most recent catalog they have for their trailer wheels and tires: https://americanatire.com/wp-content/uploads/2023/04/Kenda-ATW-Catalog-2023.pdf, there is some useful information in there as well.

Hey Jason, did the torque specs and pressure info for your Karrier tire and wheel help you get everything tightened up the way you needed? Your update could make it easier for the next person setting up the same combo.
