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 bought gauges from here and it was the best price around. They shipped it quickly and it should be here soon. Ill buy from here again.

Search to ID the right part looks good so I bought. Sure hope it fits!

Quick and easy so far!

best price I could find...just ordered the product. Hope everything else is as good.

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Easy to use web site.

Great website with very quick response time and fast shipping. Product arrived as described, however packing fell short of my expectations as manufacturer's box was taped up and components were jarred around during transit causing some pieces to be scratched. Overall, would certainly do business with the company again due to flawless customer service.

Great price. Great customer service. And fast shipping. I will be using Autoplicity again.

Good Price
