Trailer King Tires

Portland-area cargo trailers, landscape rigs, and equipment haulers put real stress on trailer tires long before a weekend getaway ever starts. TRAILER KING trailer tires are a strong fit when you need true ST replacement with the right load range, inflation target, and wheel compatibility for the work your trailer actually does. At Trendsetters Truck & Auto, that fitment-first approach matters for contractors, fleet users, and owners who tow for the job as much as for recreation.

For heavier-duty highway use, ULTRA STR is the model to compare first. Its all-steel construction and ribbed tread design make it a smart option for higher-load applications, especially when wheel capacity also needs to be verified. If your trailer needs a more straightforward replacement path, RST delivers practical value for many RV, boat, cargo, and utility trailer setups.

Trendsetters Truck & Auto can help you sort out ST sizing, load demands, and inflation needs before you buy. Start with a Tire Consultation, stop in for a Tire Pressure Check, or browse Shop Tires to find the right Trailer King setup for your trailer.
