Need Some help Choosing tires?

Understanding tire sizing conventions, such as diameter, width, and ISO (International Organization for Standardization), will help you to make the best decision when purchasing BMX tires. Different BMX disciplines, such as racing, street, and park riding, often require specific tire sizes. Racing bikes generally use narrower tires for increased speed, while street and park riders often opt for wider tires for enhanced stability and grip.

Several factors influence the selection of BMX tires, and considering these elements will help you find the perfect match for your riding style and needs.
