<h3>About Kenda Tires</h3><p><a href="/375-kenda">Kenda</a> is one of the most recognized names in the tire industry, and for good reason. <strong>Founded in 1962 in Yuanlin, Taiwan</strong>, Kenda Rubber Industrial Company started as a modest bicycle tire manufacturer and steadily evolved into a global powerhouse. Today, the brand covers an enormous range of applications — from road bikes and mountain bikes to ATVs, motorcycles, passenger cars, light trucks, trailers, lawn and garden equipment, and specialty vehicles — all built on over six decades of rubber engineering expertise.</p><p>What sets Kenda apart is the breadth and depth of its catalog. Rather than focusing on a single segment, Kenda has methodically expanded into every terrain and vehicle type where reliable rubber meets the road (or trail). Their <a href="/375-kenda-tire-7636">tire lineup</a> includes well-known series like the Klever for light trucks and SUVs, the Vezda for touring and high-performance passenger cars, the Kenetica for all-season driving, and the Komet for sports car enthusiasts — demonstrating just how far the brand has come from its bicycle-tire origins.</p><p>Kenda operates manufacturing facilities across Taiwan, China, Vietnam, and Indonesia, with a U.S. presence headquartered in the Columbus, Ohio area. With a workforce exceeding 10,000 employees across 13 global locations, the company has the scale to support both OEM and aftermarket customers worldwide. Their investment in research and development is ongoing, with a focus on improving puncture resistance, rolling resistance, tread life, and overall weight — qualities that matter whether you&apos;re commuting through city streets or charging through rocky single-track.</p><p>For riders and drivers who need reliable rubber without breaking the bank, Kenda delivers a compelling balance of performance and value. Their <a href="/375-kenda-tire-inner-tube-7640">tire inner tubes</a> are equally well-regarded, offered in multiple thicknesses — standard, tough, and super tough — to match everything from casual cycling to demanding off-road ATV use. The brand&apos;s <a href="/201075-tires-tubes-kenda-375">tires &amp; tubes</a> bundles make it convenient to shop for complete solutions in one place, whether you&apos;re outfitting a mountain bike, a trailer, or a powersports machine.</p><h3>Why Choose Kenda?</h3><ul style="list-style:disc"><li><strong>Heritage since 1962</strong> — over 60 years of continuous tire manufacturing experience</li><li><strong>Broad application coverage</strong> — bicycles, motorcycles, ATVs, passenger cars, light trucks, trailers, and more</li><li><strong>Global manufacturing footprint</strong> — production facilities in Taiwan, China, Vietnam, and Indonesia</li><li><strong>Multiple tube thickness options</strong> — standard, tough, and super tough inner tubes for varying terrain demands</li><li><strong>Diverse tire series</strong> — purpose-built lines for touring, all-season, off-road, high-performance, and trailer use</li><li><strong>OEM and aftermarket trusted</strong> — Kenda serves both vehicle manufacturers and individual consumers worldwide</li></ul><p>Whether you&apos;re replacing a worn commuter bicycle tire, upgrading your ATV setup for the trails, or putting a fresh set of all-season rubbers on your truck, Kenda has a product engineered to meet the challenge.</p>

Key Features:

  • 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
  • Designed for off-road motorcycles, dirt bikes, and dual-sport applications

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.
