So said the marketing campaign from Bridgestone at the launch of DriveGuard, their “game changing tyre innovation, which places safety and convenience in every driver’s seat. ”Contentious comment? Yes! Good solution for safer family driving? Read on and ﬁnd out what we thought…
On average, every driver can expect to have six punctures in their lifetime and 27% of all roadside emergencies are tyre related. And don’t forget, a ﬂat is not just an inconvenience. If a puncture happens rapidly, you have less control, less braking capability and are more susceptible to the prevailing road conditions. If it happens slowly, you may not even be aware you have a puncture for some time. That can affect your fuel consumption, road handling and even braking distances, particularly in wet or icy conditions. That is why all cars made after November 2014 are now required by law to have a Tyre Pressure Monitoring System (TPMS) built in. There are a variety of systems from the various car manufacturers as well as third party products that can be retro-ﬁ tted to older vehicles, but fundamentally the TPMS alerts the driver that tyre pressure is low and that there may be a problem with one or more of your tyres. Over time, all tyres will lose pressure, including your often forgotten spare, so regularly check and top up your pressures as per your car manufacturers recommended levels. Whether you’re on the school run, driving to work, going home or meeting with friends – there’s never a convenient time for a puncture. In fact, in 23% of cases, punctures happen during the evening or late at night which adds additional stress and anxiety to the situation. Of these, more than 50% happen in inconvenient locations and no driver wants to ﬁ nd themselves stranded, changing their tyre on the side of a busy road, in the dirt, in the rain, in the dark. Particularly if you’ve a young family on board. It’s perhaps no surprise that 72% of women and 33% of men don’t change their own tyre. However, if there’s no cellphone reception to call for assistance – you’re on your own!Where is the spare? Has it any air in it? Is it under all the luggage? Where are the locknut keys? Where is the jack? No wheel spanner! Is that skinny temporary thing really the spare? You ﬁll it with what!?
With over 60% of drivers experiencing a puncture in the last four years – leading to feelings of helplessness and insecurity combined with lost time of up to three hours – the Bridgestone team have comeup with a very, very good answer to the problem. DriveGuard can, in practically all conditions, help prevent accidents resulting from punctures, sudden loss of pressure or other types of tyre damage. It provides a safe and reliable solution, allowing drivers to wipe their hands clean of inconvenient puncture scenarios.So how does it work?
At the moment of puncture, you still have complete control over the vehicle and are made aware of the problem by your PTMS on the dash. You can continue to move with the trafﬁc without immediately having to pull over or risk driving on and shredding the tyre. A ﬂat tyre leads to rubber deformation which generates heat or friction; by using a special patented compound, Bridgestone has created a high-tech cooling ﬁ n design in the sidewall that channels the increased heat from the sidewall towards the rim and thus helps to preserve the tyre.Based on state of the art technology, DriveGuard’s sophisticated tread pattern helps evacuate water to resist hydroplaning, while engineered sipes increase the number of biting edges to enhance wet road traction. As a result, Bridgestone DriveGuard has achieved the highest rating in wet grip performance (EU Tyre Label: A grade) with short braking distances, while offering a level of comfort comparable to conventional tyres, placing it at the frontline of road safety.The new age DriveGuard technology uses a proprietary high-tech cooling ﬁn design as well as supportive and tough reinforced sidewalls which allow drivers to maintain control and continue driving safely and comfortably for 80km at up to 80kmph (50 miles at 50mph) after a puncture; fast enough and long enough to arrive safely at their desired destination or to seek assistance at a convenient service point.We drove a standard saloon car, with a deliberately punctured tyre for over 10km, and it handled just like a normal car. In fact, one of the other review teams managed to have a SECOND puncture during testing, and drove trouble free with both front tyres blown!“Bridgestone DriveGuard empowers you to keep moving and avoid the immediate burden and unsafe circumstances of a ﬂ at tyre; drivers get to choose when and where they have their tyre replaced – within the indicated speed and distance limits. Our revolutionary new technology will considerably contribute to road safety and give drivers additional peace of mind and convenience while on the road,” said Eduardo Minardi, Executive Chairman of Bridgestone EMEA. Bridgestone DriveGuard eliminates the need to carry a spare tyre and is environmentally conscious due to being fully recyclable. That means less weight so less fuel and 20% fewer tyres required per car so less material required.Despite the impressive safety beneﬁ ts and convenience advantages, a full set is only marginally more expensive than any other premium tyres of the same size. Your vehicle will be safer, lighter and have more space on board.So, in our opinion Driveguard offers a major contribution to road safety and all family cars should have them ﬁ tted whenever practically possible!
