Tested beyond the limits.

" Davanti tyres combine expert engineering, advanced manufacturing processes, extensive testing and progressive development. We put tyres through rigorous test regimes to ensure they deliver safe and predictable handling and a comfortable drive. Our tyres allow the driver to get the most out of their vehicles performance capabilities, and therefore deliver excellent value for money to users. "

Dry braking test consists of driving vehicle at high speed, then applying brakes.

The distance covered by the car when coming to a complete stop is measured by ultra-precise GPS equipment.

X

Dry handling

In our testing we grade performance parameters across four categories:

  • Ride
  • Steering
  • Stability
  • Noise

Tests areconducted both at high speed – pushing the tyres beyond the limit of their grip – and also at typical driving speeds over a range of controlled surfaces and bumps. Dry handling is not all about high speed performance. Top lap times are not relevant on dry roads. Tyres should provide safety reserves when taken to their limit and their road performance should be effortless and predictable since this helps a driver to relax and avoid driving errors. For this purpose, the test driver evaluates the reaction to steering input and cornering as well as rear axle stability. They look for how tyres react to changes in direction and pace, the amount of steering lock required and for any loss of grip to be progressive.

X

Wet handling

Wet handling testing consist of both objective and subjective tests.

The objective test parameter measured is the time taken for a high-speed lap of a wet handling circuit. This is a broad ranging test that takes in to account a number of tyre performance attributes, such as the tyre’s ability to transfer the car’s power to the road, and ultimately the amount of control the driver has. The subjective test goes beyond the lap time to give a greater insight in to the tyre’s performance. The test driver applies a rating to a number of parameters, based on their knowledge and experience. They are focusing on driver experience – looking for safe, predictable handling, and effortless road performance.

X

Longitudinal aquaplaning

The speed at which a tyre is deemed to by fully aquaplaning is when the front driven wheel speed is 15% faster than the speed the vehicle is actually travelling

The higher the speed achieved before full aquaplaning is reached, the better the tyre is at preventing the phenomenon. Davanti's testing process creates the conditions for aquaplaning to engineer tread patterns that break up the surface of the water and drive it away from the contact area more effectively.

X

Dry stability

On a demanding dry handling track, the tyre is rated on the following characteristics:

  • Roll control
  • Yaw stability
  • Lateral grip
  • Lateral stiffness
  • Throttle lift-off
  • Straight line stability
X

Dry steering

  • Driving effort
  • On-centre feel
  • Steering response
  • Linearity
X

Wet circle

The vehicle is driven on a wet asphalt circle with constant steering angle applied, thus maintaining a consistent diameter.

The vehicle is accelerated up to a speed at which grip is lost, with the lap time at this speed measured by data logging equipment.

X

  • Controllability at limit
  • Power on/off cornering

Ice braking

Preventing that dreaded moment when you hit the brakes on ice and the vehcle just starts to slide is a key expectation of winter tyres

Ice traction is tested by measuring the time taken to accelerate to a predetermined speed. The ice braking test measures the distance covered when slowing from this speed to a stop. These tests are carried out on a carefully prepared and controlled brushed ice surface.

X

Ice acceleration

The vehicle is driven from a standing start up to 20 km/h. Data logging equipment measures the time taken for the vehicle to accelerate from 5 to 20 km/h.

X

Ice handling

We test ice handling at the 1,300 metre track at Ivalo in the Arctic Circle

A fast and flowing series of tightening ice turns and hairpins really tests the tyres. All are negotiated with any electronic driver aids disabled - ensuring the only things keeping the vehicle on-track are the driver and the tyres. The track is graded between runs and the result decided by an average of lap times.

X

Snow stability

On a hard packed snow track, the tyre is rated on the following characteristics:

  • Controllability at limit
  • Power on/off cornering
  • Transient stability
  • Brake-in-turn
  • Braking stability
X

Snow steering

On a hard packed snow track, the tyre is rated on the following characteristics:

  • Feel/weight (on centre)
  • Feel/weight (off centre)
  • Response (on centre)
  • Response (off centre)
  • Linearity

Snow braking

The vehicle is driven onto a medium-packed snow surface at a steady 45 km/h.

The brakes are applied and sophisticated data logging equipment measures the distance covered between 40 and 5 km/h.

X

Snow acceleration

The vehicle is driven from a standing start up to 40 km/h.

Data logging equipment measures the time taken for the vehicle to accelerate from 5 to 40 km/h.

X

Snow handling

Snow handling is tested on Test World’s demanding Alpine Circuit.

Featuring tight hairpins, long straights, steep elevation changes and off-camber corners, this facility goes far beyond the typical conditions encountered by most motorists. Our testing consists of repeated timed runs on this track, to ensure the performance of our tyres consistently and reliably meets and exceeds the performance requirements of drivers on snow-covered roads.

Sand traction is evaluated in two ways:

  • Using a sand hill, the maximum achievable distance the vehicle can reach is measured.
  • Using a sand hill, the minimum achievable time for the vehicle to reach the top is measured.

Dry
braking

Drivers don't practice emergency stops - when you need to perform one you need to know that your car will halt in a safe and composed manner.
