Avon Inner tubes

In the following tables you can find our assortment of Butyl and Natural rubber inner tubes. For fitments please check the tables below.



Butyl Rubber
Synthetic rubbers are more resistant to oil, certain chemicals and oxygen, have better aging and weathering characteristics, and good resilience over a wider temperature range. Butyl is less permeable than natural rubber so good for preventing air loss.
Natural Rubber
Natural rubber has good wear resistance, high elasticity, high resilience, and tensile strength. It has a good dynamic performance and low level of damping. However, it ages with time and has poor chemical, oil, and ozone resistance. It has poor resistance to elevated temperatures. Customers who want a heavy duty tube tend to go with the natural rubber ones.



Butyl Rubber
Fitments for 10" to 21" rims.
