Z Testing


Testing, testing...


We aim to construct the very best tyres. But what does that involve?
Each tyre with the distinctive Z logo on the sidewall must meet the highest standards - and there's no higher benchmark than the one we set ourselves.
There are many individual procedures that test every possible subjective and objective parameter. But to ensure that our premium Z tyres meet such demanding expectations, we've developed our own independent testing schedule. Such tests extend well beyond the legally required test criteria.

We call it Z-360 ° testing

Complete customer satisfaction is our number one goal. So we don't just look at the objective tyre test criteria, but also the more nuanced subjective tests that involve wet and dry road handling, driver 'feel' and vehicle stability especially at high speeds . At the independent IDIADA proving ground in Spain, numerous tests are performed and repeated to our exacting standards.

Wet weather testing


Wet handling

Wet braking behaviour

Wet traction

Aquaplaning in a straight line

On dry roads


Handling in dry surface conditions

Braking performance on dry roads

Driving stability at high speeds

Cornering behaviour


Grip on road bends

Aquaplaning in curves

Noise testing


Interior noise for driver comfort

External 'pass by' noise

Set a New Standard


And many more tyre test criteria, where we perform comparative tests against competitive benchmarks to see how we compare and how we can perform even better.

Our goal


Every driver running on Z tyres can always be confident of the very best performance.
