🔵 Tire Type

The ENGWE P275 ST comes equipped with knobby tires, meaning its tread features pronounced, widely spaced lugs that typically stand 4–6 mm tall. Those blocky knobs dig into loose or uneven ground—gravel, dirt trails, even light mud—by flexing and biting into substrate. To maximize grip, riders often run pressures between 30 and 45 psi, which further softens the tire’s footprint for better traction. The trade-off is rolling resistance: knobby tread can increase drag by 20–30 percent compared with a slick or hybrid tire, so you’ll feel more effort on smooth pavement.

On a paved road or bike path, these knobby tires will usually shave off around 10 percent of your potential top speed and may feel slightly slower to accelerate compared to smoother-treaded e-bikes. But the moment you hit gravel back-roads, fire lanes, or light singletrack, that extra bite pays dividends in stability and control. The P275 ST’s tires help the bike maintain traction on loose corners and ascend steeper pitches where a slick tire would spin out or slide.

These knobby tires matter most to riders who split their days between street commuting and off-road exploration—or anyone who wants the confidence to stray from pavement without swapping wheels. If your ride is almost entirely on smooth asphalt, you might prefer a tire with a finer tread or lower rolling resistance. But for mixed-terrain adventures, forestry or ski-access roads, and quick detours onto rougher paths, the P275 ST’s knobbies deliver predictable grip and peace of mind.
