Do you have a question about GI-378 445/65R22.5 L 168K?
The Falken GI-378 is a commercial truck wide-base radial tire engineered for both on-road and off-road service. It belongs to Falken's GI-Series — the brand's most durable commercial lineup — and is specifically designed for medium-duty and heavy-duty trucks that operate in demanding mixed-service conditions such as cement, dump, and utility applications.
The Falken GI-378 is designed for medium-duty commercial trucks operating in on/off-highway environments, including cement trucks, dump trucks, waste haulers, and utility vehicles using wide single (super single) axle configurations. Its up to 20-ply rating and cut-and-chip resistant compound make it well-suited for construction sites, quarries, and any application that alternates between paved roads and rough terrain.
The Falken GI-378 is available in three wide-base sizes: 385/65R22.5, 425/65R22.5, and 445/65R22.5. These wide single sizes are designed to replace dual rear tire configurations on equipped axles. Visit the product page on neotires.com for current stock availability, or contact our team to confirm the correct size for your truck's axle configuration.
The Falken GI-378 is built around three core performance features. First, wide outer ribs deliver on-road stability and handling confidence even under heavy loads. Second, stone defense features prevent rocks and pebbles from packing into the tread grooves and drilling into the belt package or casing, which is critical for off-road and mixed-surface work. Third, a cut-and-chip resistant tread compound uses a softer, flexible rubber formulation that absorbs impacts and resists punctures during operation on rough or loose terrain.
The Falken GI-378 is rated up to 20-ply (Load Range L), giving it an exceptional load carrying capacity suitable for the heaviest wide-base truck and commercial vehicle applications. The 385/65R22.5 size carries an 18-ply (Load Range J) rating at 158K load index, while the 425/65R22.5 and 445/65R22.5 sizes step up to 20-ply (Load Range L) for maximum load support. Always verify the load index against your vehicle's GVW requirements before purchasing.
Yes, the Falken GI-378 is backed by Falken's 6-Year Casing Warranty. Falken also provides dedicated fleet support through sales engineers, customer account managers, and quality assurance technicians to help minimize downtime and maintenance costs.
