Trailer King Tires

Bought a used camper or older utility trailer and not sure what those sidewall numbers are telling you? TRAILER KING trailer tires are a practical place to start when the real question is fitment, not just tread. For trailer-only ST replacements, size, load range, rim width, and required cold PSI all need to line up before you tow. That’s where Discount Tire & Automotive Inc. helps take the guesswork out of replacing aged, cracked, or questionable trailer tires.

If you’re comparing heavier-duty options first, ULTRA STR is worth a close look for higher-load and highway-focused applications. If your trailer doesn’t need that step-up, RST is the simpler everyday replacement for many RV, boat, cargo, and utility setups. In many cases, the better choice is the one that matches your actual trailer weight and wheel specs, not just the highest load range on the shelf.

Before you order the wrong setup, let Discount Tire & Automotive Inc. review your trailer specs with a Tire Consultation, or browse Shop Tires to compare available Trailer King fitments.
