Towmax STR II

The Power King Towmax STR II tires are a trailer-focused replacement option for shoppers at Gunnell's Tire & Auto who want straightforward load support and simple size matching. Built for trailer use only, this model is a practical fit for towable applications where correct sizing and load range matter most.

Choose from three approved sizes: 205/75-14, 205/75-15, and 235/80-16. The 205/75-14 and 205/75-15 fitments are Load Range D with a 65 psi max inflation, while the 235/80-16 steps up to Load Range F with a 100 psi max inflation. All listed fitments carry an L speed rating for on-highway trailer service.

If you are replacing OE-style ST trailer tires on a travel trailer, fifth wheel, utility trailer, or similar towable, Gunnell's Tire & Auto can help you match the right size and load range. For more Power King options, visit the Power King tire brand page or start browsing Shop Tires.
