Upgrade your rig with the pre-mounted Kenda® Loadstar K550 ST175/80D13 Bias Tire & 13x4.5 Gloss Black Steel MOD Wheel Package!

Eliminate the hassle of separate mounting and balancing with this complete, ready-to-bolt-on trailer wheel and tire assembly. We have paired Kenda’s dependable Loadstar K550 ST175/80D13 6-ply bias trailer tire (Load Range C) with a rugged Kenda 13x4.5 Zero-Offset Steel Modular (MOD) wheel finished in a durable e-coated gloss black coating. This tried-and-true setup delivers proven tracking stability, high payload capability, and long-lasting durability across light-to-midsize utility trailers, tow dollies, boat trailers, and job-site equipment haulers.

The Loadstar K550 tire is engineered with a broad, flat tread profile that evenly distributes tongue and cargo weight across the road surface to significantly reduce high-speed sway and wander. Formulated with an advanced rubber compound to decrease rolling resistance and heat build-up, the tire is paired with a heavy-gauge roll-formed steel wheel boasting an impressive 1,725 lb wheel load capacity, a standard 5-on-4.5" (5-4.5) bolt circle, and a 3.19" center pilot bore. Rated for highway speeds up to 81 mph (M speed rating), this pre-mounted package takes the stress out of towing.
