Frequently Asked Questions

1. Are these tires tubeless‑ready (TR)?

No. These are clincher tires and designed for using with inner tube. 

2. How could I find out the tire size?

Most tires have their size (in inches) or an ETRTO number marked on the sidewall (with the exception of some older bicycle tires). If you are still unsure, please feel free to contact our customer service team.

3. How many miles can these tires last?

Service life depends on terrain, rider weight, inflation and maintenance. Each tire we list its suitable terrains. It can last 1,500–2,500 miles on those surfaces.

4. When will I get my order?

Normally, your order is processed and handed over to our logistics partner within 1–2 days of placement, followed by a shipping period of 3–5 days. We will provide you with the tracking number as soon as it becomes available.

We offer a 30-day return policy on all products returned to us in new (unused) condition. We cannot accept returns of used products or after 30 days. Buyers are responsible for return shipping & restocking fees for non-quality returns. Thank you for your understanding.
