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>

Product Details

The Loadstar Tires 31986 is a complete ST185/80R-13 radial trailer tire and wheel assembly designed for boat trailers, utility trailers, and other towing applications. This ready-to-mount package combines a durable ST (Special Trailer) radial tire with a 13-inch silver directional wheel, saving you time and ensuring proper tire-to-rim fitment.

Key Features:

  • ST185/80R-13 radial tire size with 13-inch diameter rim
  • Load Range C construction for 1,360 lbs maximum load capacity at 50 PSI
  • 5-hole bolt pattern (5 on 4.5-inch) fits most standard trailer hubs
  • Directional silver wheel with corrosion-resistant finish
  • Radial construction provides cooler running temperatures and longer tread life
  • Pre-mounted and balanced for immediate installation
  • DOT approved for highway use

This complete assembly eliminates the need for separate tire mounting and balancing services. The directional tread pattern enhances water evacuation for improved wet weather performance, while the radial design delivers a smoother ride and better fuel economy compared to bias ply tires. Ideal for trailers requiring a 13-inch wheel with 5-lug mounting.

Quick and easy

Very prompt shipping and item was exactly what I needed. Found it cheaper than any other site I viewed and shipping costs were reasonable- not so much with some of the other sites. Would definitely use this seller again for auto parts.

Product install was a pain and parts didn't fit together properly, but the experience from autoplicity was great

Good job thanks

I ordered on Sat. Dec 29th. With the new year holiday, I expected package to arrive on Wednesday. Was told it would arrive Thursday by the end of the day. I did not receive it until Friday afternoon.. In short, they shouldn't say 2 day delivery, since it took 6 days. I am however very happy with the product I ordered.

Very good company to do business with

great prices with easy searching.

Great selection

Awsome website! Very easy to use and I really like the option to use Paypal for my order.

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

This is the first order that I have placed with Autoplicity. I found that they had the best price for the product that I ordered and also had some very good reviews from other satisfied customers.<br>
