1, original self-supporting technology, giving consideration to gas retention and support.
2, high strength matrix design, strengthen the self-supporting effect.
3. The new anti-slip ring design ensures that the tire lip is firmly attached to the rim under zero air pressure.
Zheng Xin is safe and reliable. It can still keep the speed of 30KM/H under the condition of zero air pressure, and ride over 80KM, which is far ahead in the same industry.
