Every single raw material component is subject to established steps of quality control before it enters into production.
Every batch of the tread compound mixture is tested in the laboratory. Resulting quality protocol is archived for number of years.
Test run of tubular tyres / tubular clinchers is produced from every batch of a cord composite. These tyres are tested under extreme conditions in our dynamic laboratory for few thousand kilometers.
Every finished tyre is marked with a unique serial number – tyre birth certificate – indicating who and when built the tyre, casing material and tread material.
Tyre vulcanization is automatically computer controled. Every finished tyre comes with a protocol about the tyre vulcanization progress archived for number of years.
Every finished tubular tyre/tubular clincher is tested for air leaks. Inflated to 10 bars – 145 psi for 24 hour period.
Our final quality control specialist tests every finished tubular tyre/tubular clincher for roundness, correct size and overall finish. This is done visually and by hand, inch by inch around the tyre. Size is checked with a special measuring instrument.
Our products are tested with state of the art laboratory equipment:
Our tyres are also tested by professional teams and number of individual top athletes in real world conditions.
