寬胎越野輪胎 / Alpha Four

The wider knobby tread made a huge difference on the gravel path behind our house — way more grip than the stock tires. Install was easy on the original rims and they've held air fine after a few weeks.

The extra width on these tires made a noticeable difference in grip on our local singletrack. My daughter feels much more confident cornering on loose dirt now.

Swapped these onto my kid's bike for the wider trail setup and the extra width made a real difference on loose gravel. He's way more confident on the descents now, and honestly I didn't expect tires to change the ride this much. Great replacement option if you want a beefier feel on the Alpha Four.
