Loadstar Tires

<h3>About Loadstar Tires</h3><p>When it comes to keeping trailers safely rolling across North American roads, few names carry more recognition than <strong>Loadstar</strong>. A flagship brand of Kenda Americana Tire &amp; Wheel — the distribution arm of global tire manufacturer Kenda — Loadstar has spent more than 50 years earning its reputation as a go-to solution for towable trailer, utility, RV, marine, and agricultural applications. Whether you&rsquo;re hauling a boat to the lake, moving cargo on a utility trailer, or heading out for an extended RV trip, Loadstar products are engineered with the demands of the road firmly in mind.</p><h3>Engineering &amp; Heritage</h3><p>Loadstar tires are engineered, designed, and tested at the Kenda Technology Center in Akron, Ohio — a facility dedicated to pushing the performance and durability limits of trailer tires. Kenda Americana operates multiple large distribution centers across the United States, ensuring consistent availability and quality control from the point of manufacture through to delivery. This end-to-end oversight — spanning design, manufacturing, quality control, and distribution — is what sets Loadstar apart in the special trailer (ST) tire segment.</p><p>The brand&rsquo;s lineup includes both bias ply and radial construction tires built specifically for trailer use. Unlike passenger or light truck tires, Loadstar&rsquo;s ST-rated tires are constructed to handle the unique stresses of being towed — including side-load forces, heavy cargo weight, and extended highway speeds. Models like the K353, K364, K397, and K550 cover a wide range of trailer sizes and load requirements, from compact boat trailers to heavy-duty commercial haulers.</p><h3>Tires Built for the Trailer</h3><p>At the core of the Loadstar lineup are its <a href="/7439-loadstar-tires-tire-7636">trailer tires</a>, offered in a broad spectrum of sizes, load ranges, and construction types. Loadstar ST tires feature advanced rubber compounds designed to maximize tread life and reduce rolling resistance, while their bias ply construction creates a flexible yet load-tolerant sidewall that minimizes trailer sway during towing. All tires are manufactured to meet or exceed Department of Transportation (DOT) highway use requirements, giving trailer owners confidence on every journey.</p><h3>Wheels Matched to the Task</h3><p>Loadstar&rsquo;s approach to trailer safety doesn&rsquo;t stop at the tire. The brand also offers a comprehensive range of <a href="/7439-loadstar-tires-wheel-7644">trailer wheels</a> — including steel, galvanized, and aluminum options — designed to complement their tire lineup. From classic spoke-style steel wheels to premium aluminum designs like the Galvstar&trade; galvanized wheel, there&rsquo;s a Loadstar wheel to match virtually any trailer setup. Properly matching the right wheel to the tire and axle load rating is critical for safe towing, and Loadstar&rsquo;s coordinated tire-and-wheel system makes that process straightforward.</p><h3>A Trusted Partner Across Industries</h3><p>Loadstar products are found as original equipment on trailers from major manufacturers across the United States and Canada. Their reach extends across boat trailers, snowmobile trailers, RV towables, agricultural equipment trailers, and utility haulers — a testament to the brand&rsquo;s versatility and the trust that both OEM builders and end-users place in their performance. For anyone seeking reliable, purpose-built trailer tires and wheels backed by decades of industry experience, Loadstar remains a proven benchmark.</p>

I ordered my Auto Vent Shade bug deflector 18174 on Thursday afternoon, June 14, 2012, and had it on my front porch by Tuesday, June 19, 2012. I thought that was fast shipping, especially considering there was a weekend involved. The price was also very reasonable. I am anxious to install my new bug deflector. I will be turning to Autoplicity in the future for my auto needs. Great Job Autoplicity!
