Radial STR II

Towmax Radial STR II is a special trailer radial built for towable applications like travel trailers and fifth wheels. Towmax Radial STR II tires are a practical choice for Advantage Tire Pros shoppers who want trailer-specific load support and steady highway towing in a straightforward replacement tire.

This compact lineup covers common trailer sizes from 13 to 16 inches, with load ranges C, D, E, and F available to help match different trailer weight needs. Available fitments include 185/80-13, 205/75-14, 205/75-15, 235/80-16, 235/80-16, and 235/85-16. All listed fitments carry an L speed rating for highway trailer use.

If you need a trailer-only replacement tire, the Radial STR II keeps the focus on load-carrying confidence and fitment variety rather than extra performance claims. Contact Advantage Tire Pros for help choosing the right load range for your towable, or start with Shop Tires to browse more options.
