Four New Sizes, One Familiar Name: Sailun Widens the TerraMax AT2 Lineup

Why a Size Expansion Is Bigger News Than It Sounds

A new tire size rarely makes headlines the way a new product launch does, but for the people who actually decide what goes on a vehicle, it can matter just as much. A brand-new tire model means nothing to a driver if it simply does not come in the size their vehicle needs. Sailun's decision to expand its TerraMax AT2 all-terrain tire with four additional sizes is a smaller announcement than a full product launch, but it solves a very specific, very practical problem: fitment gaps that were quietly pushing potential buyers toward competitors.

The TerraMax AT2: An Established Name, Not a New Bet

The TerraMax AT2 was not a fresh, unproven product when this expansion was announced. It is an established all-terrain tire in Sailun's light truck and SUV range, engineered for drivers who split their time between paved roads and rougher terrain. The tire carries Three-Peak Mountain Snowflake certification, confirming its performance in severe snow conditions, and features an updated tread design aimed at supporting stable handling across mixed surfaces.

It is also backed by Sailun's limited warranty, including a two-year, no-charge Road Hazard Replacement Program, and has received the Today's Parent Approved badge, a recognition tied to safety, durability, and family-friendly performance. In other words, this is a tire that had already built a track record before the size expansion, which is precisely why extending its fitment range matters: Sailun was not introducing an unfamiliar product to new customers, it was making a trusted one available to more of them.

The Four New Sizes

In December 2025, Sailun Tire Americas added the following sizes to the TerraMax AT2 lineup:

With this addition, the TerraMax AT2 lineup now spans six flotation sizes in total, giving it broad coverage across multiple vehicle segments, from smaller SUVs and light-duty pickups through to heavy-duty full-size trucks.

Closing the Gaps That Actually Cost Sales

According to Jack McClure, manager of segment PLT product development at Sailun, the expansion reflects the company's continued focus on vehicle fitment and product coverage, with the team monitoring the market closely and updating the lineup to support the needs of all customers. That framing points to something specific: tire buying decisions are often made from the vehicle outward, not the brand inward. A driver does not typically choose a tire brand first and then find a vehicle to match. They start with the vehicle they already own and search for tires that fit it, in the size, load rating, and speed rating their manufacturer specifies.

When a well-regarded tire line is missing a common size, that gap does not just cost a single sale. It can push a driver toward a competitor's product for their entire ownership period, since most drivers replace like-for-like once they find a tire that works. Filling fitment gaps in an already-trusted line is, in that sense, a direct and efficient way to capture demand that would otherwise be lost.

The New Addition Worth Watching: 275/50R22 115T XL

Among the four new sizes, the 275/50R22 XL stands out. It extends the TerraMax AT2's coverage specifically into heavy-duty pickups and full-size SUVs, a segment that tends to be dominated by larger rim diameters and higher load ratings. According to Sailun, this addition maintains coverage for that heavy-duty category while simultaneously opening up fitment options for smaller SUVs and light-duty pickup trucks through the other three sizes, meaning the expansion was designed to cover both ends of the light truck and SUV spectrum at once, rather than deepening coverage in a single segment alone.

What This Signals About Sailun's Product Strategy in North America

This kind of incremental, fitment-driven update is easy to overlook next to a splashy new product launch, but it reveals something about how Sailun is approaching the North American market. Rather than only chasing headlines with entirely new tire lines, the company is also treating its existing, proven products as ongoing assets worth continuously expanding, guided directly by where the market gaps are. That is a maintenance-and-growth strategy as much as it is a marketing one, and it depends on having a product already trusted enough to be worth extending in the first place.

For dealers and distributors, a size expansion like this carries a simple, practical message: before assuming a customer's vehicle is not covered, it is worth checking the current TerraMax AT2 size chart again. A gap that existed a year ago may no longer be there.
