Where is the tire tread pattern model located?

The tire tread pattern model is marked on the sidewall of the tire. Here is relevant information: 1. Generally speaking, tire tread refers to the various longitudinal, transverse, and diagonal grooves on the tire's tread surface. Tire tread patterns can be categorized into three basic types: longitudinal, transverse, and mixed. Longitudinal tread patterns excel in water drainage and help with tire cooling, but they lack sufficient grip. 2. Transverse tread patterns have high lateral stiffness, providing strong grip, but they perform poorly in water drainage and directional stability. Mixed tread patterns combine the advantages of both longitudinal and transverse treads, offering excellent grip and water drainage performance. They are suitable for both dry and wet road conditions with fewer usage restrictions.
I just changed my tires the other day and made sure to check the tread pattern model location. It's right on the most visible part of the tire sidewall, usually near the rim edge. That combination of letters and numbers is it—for example, my tire is engraved with 'GOODYEAR EAGLE F1' plus something like 205/55R16. You'll need to squat down to look for it, and running your fingers over the embossed letters is faster than searching with your eyes. Different brands place it slightly differently: Michelin tends to put it below their logo, while Bridgestone often positions it in the center of the sidewall. Actually, the tread pattern model isn't just for identifying the tire; checking the TWI (Tread Wear Indicator) mark lets you know the wear level—when the three drainage grooves become shallow, it's time to replace the tire.
When changing tires, pay attention to the sidewall where the tread pattern and size specifications are engraved. With over a decade of experience in auto repair, I often get this question from customers. These details are usually embossed in raised alphanumeric characters along the outermost black rubber, such as 'CONTINENTAL PC6 225/45R18'. Don't confuse this with the DOT manufacturing date - the tread pattern is typically located near the brand logo. Michelin even prints a small mountain-and-man symbol next to their tire codes for easy identification. For routine maintenance, use a coin to check tread depth - if Washington's head remains covered when inserted into the grooves, your tires are still safe.
Long-haul drivers know that the tire tread pattern directly affects wet road grip. It's located on the sidewall of the tire, visible when you bend down during your pre-drive walk-around inspection. Look for the most deeply embossed raised characters - on my Goodyear tires, the tread pattern code is positioned opposite the valve stem. Actually, the combination of numbers and letters in the code reveals useful information: the ending letter indicates speed rating, while the middle number shows the aspect ratio. Once when I had a nail puncture, the tire repair technician matched the exact same tread pattern using this code. For highway driving, it's recommended to check monthly, especially the front tires which wear faster.
