Formed in 1952, Panaracer began manufacturing rubber products for a variety of commercial and consumer applications.
Since then, we began to exclusively produce bicycle tires so we could carefully focus on producing the finest tires available today.
Panaracer is the last Japanese manufacturer still producing bicycle tires in Japan.
We feel that maintaining our domestic production allows us to maintain our quality control at the highest levels.
