<h3>About Kenda Tires</h3><p><strong>Kenda Rubber Industrial Company</strong> has been crafting pneumatic tires since 1962, when it was founded in Yuanlin, Taiwan with a singular focus on bicycle tires. Over the decades, the company grew far beyond its roots — expanding into motorcycle and scooter tires, then into trailer, lawn and garden, and passenger car lines — all while maintaining its own manufacturing facilities across Taiwan, mainland China, Vietnam, and Indonesia. Today, Kenda is recognized worldwide as a vertically integrated tire manufacturer that controls a significant share of its own production, lending the brand far more substance than a typical budget label.</p><p>What sets Kenda apart is the remarkable breadth of its lineup. Whether you're fitting out a passenger sedan, a light truck, an ATV, a bicycle, or a specialty application like a wheelchair or golf cart, Kenda has engineered a tire for the job. The brand's engineers balance real-world performance with accessible value — making Kenda a go-to choice for riders and drivers who want dependable traction, solid durability, and a practical price point. On the road, on the trail, or on the racetrack, the Kenda philosophy centers on delivering tires that perform where it counts.</p><p>In the passenger and light truck segment, Kenda offers a wide range of <a href="/375-kenda-tire-7636">tires</a> covering all-season touring, ultra-high-performance, highway, all-terrain, and mud-terrain applications. Models like the Klever and Vezda series address everything from daily commuting to weekend off-road adventures. For specialty and powersports vehicles, Kenda's dedicated <a href="/375-kenda-tire-201524">tire</a> lineup covers the unique demands of ATVs, trailers, and other non-standard applications.</p><p>Beyond the tire itself, Kenda is equally well-regarded for its <a href="/375-kenda-tire-inner-tube-7640">tire inner tubes</a>, which are available for bicycles, motorcycles, and powersports machines in a wide variety of sizes and valve configurations. From lightweight performance tubes for road and gravel cycling to heavy-duty options built to withstand rugged off-road terrain, Kenda's tube lineup reflects the same commitment to quality and breadth that defines the brand as a whole.</p><h3>Why Choose Kenda?</h3><ul><li><strong>Over 60 years of tire manufacturing experience</strong>, starting from bicycle tires and growing into one of the world's most diverse tire portfolios.</li><li><strong>Vertically integrated production</strong> across multiple facilities in Taiwan, China, Vietnam, and Indonesia — meaning Kenda controls quality from the ground up.</li><li><strong>Broad application coverage</strong> spanning passenger cars, SUVs, light trucks, bicycles, motorcycles, ATVs, trailers, and specialty vehicles.</li><li><strong>Performance-to-value balance</strong> that makes Kenda a trusted choice for everyday drivers, outdoor enthusiasts, and powersports riders alike.</li><li><strong>Comprehensive inner tube selection</strong> with options ranging from standard butyl tubes to premium lightweight and heavy-duty variants for virtually any wheel size.</li></ul><p>Whether you're replacing a worn set of all-season tires on your daily driver or sourcing a reliable inner tube for a mountain bike adventure, Kenda's deep catalog and decades of rubber-engineering expertise make it a brand worth considering at every turn.</p>

  • Premium butyl rubber construction for excellent air retention and durability
  • Fits tire sizes 325-21 and 350-21
  • TR-4 straight rubber valve stem for reliable inflation and sealing

Kenda inner tubes are engineered to provide reliable performance across a wide range of riding conditions. The butyl rubber compound offers superior puncture resistance and maintains proper air pressure longer than natural rubber alternatives.

First of all, I can not believe how fast I recieved my order, 2 DAYS! Best of all, the instructions made it easy for a non mechanic like me to install.

Autoplicity so far has been great place to buy online automotive stuff. Good prices and well organized.

I think having the type of car that the parts match would be alittle more helpful.

Easy

Best price I could find, easy to order and pay thru Amazon, so far so good

Always really great prices from these guys. Believe me, I always look around and always come back to autoplicity. I ordered a super heavy part and shipping was very reasonable. This is my 5th order with these guys. Very happy customer.

Easy!

Fast shipping, good customer service!

Found a Thule Vertex bike hitch on here for $50 cheaper than amazon. Extremely fast shipping. Definitely recommend purchasing from here.

easy to use website

I think I had to remind them to ship my item but once I did it shipped the next day. The package had the wrong label on it so I wondered if I got the right item but I did and all is well.

Placed an order first part of the week, great service and price so I'm back.
