The latest addition to the range has been designed with the technological features and benefits of a run flat in mind, whilst maintaining the ability to deliver extraordinary levels of performance.
Following an extensive testing and development programme at industry leading proving grounds in summer conditions, the brand new tyre offers peace of mind to motorists – thanks to its runflat technology – and superior levels of grip, endurance and comfort, to allow drivers to excel on the road, whatever the destination.
The tyre has been developed and tested to vehicle manufacturer OE standards, equal to a premium runflat tyre. Davanti has gone above and beyond the standard requirements for runflat testing to ensure optimal performance. In addition to the standard drum test, this includes;
Pop-on pressure, ensuring that the tyres are easy to mount onto and dismount from the rim – a typical challenge for runflat tyres – whilst maintaining sufficient force on the wheel for reliable operation.
RPA sensitivity test, ensuring the tyre is well within the tolerance bounds of TPMS sensors, this test determines the variance in circumference between inflated and uninflated states, for vehicles that rely on this technology to detect that a tyre has deflated.
Rim roll-off test, ensuring that the deflated tyre stays mounted to the rim when undergoing lateral forces, a factor that cannot be determined by the standard drum test alone. This test was carried out by performing J turns with a tyre under zero pressure to ensure it remains mounted to the rim as required for OE standards.
Key features of the Protoura Sport DSP Runflat which allow the tyre to deliver leading performance and balance the technical attributes of run flat tyres include:
Self-supporting internal sidewall to support the weight of the vehicle and retain the tyre structure when it loses air as a result of a puncture, allowing motorists to safely travel to a nearby garage or place of repair.
Lateral and transverse load support when operating at zero inflation pressure.
Continued and safe operation at speeds of up to 50mph whilst deflating or deflated.
Integrated rim protection to prevent wheel damage.
These engineering innovations don’t compromise the performance of the Protoura Sport however. Instead they complement the Protoura Sport’s solid outer block pattern for precise steering response, wide longitudinal grooves to enable efficient water dispersion and solid circumferential centre grooves for straight line traction.
Davanti Tyres’ General Manager Peter Cross comments: “Expanding the Protoura Sport range to include runflat technology means drivers can enjoy our ultra-high performance tyres with the peace of mind that should they suffer a puncture, they have time get to a garage or find a safe, level area to change the tyre.
“Also, thanks to the team’s incredible work to engineer a UHP tread pattern alongside runflat technology which has been developed to a premium standard, means we have a tyre which is a leading benchmark for runflats that offers performance you can trust.”
The tyre will be available in sizes 17” to 21”.
