Bridgestone has announced the launch of its new semi-slick Bridgestone Potenza Race tyre. 

The company said in a statement that the tyre would deliver lap times that beat all main competing tyres, along with the best braking performance in dry conditions. The tyre is homologated for public roads, but with performance focussed on track days. 

The Potenza Race is the latest addition to Bridgestone’s Potenza tyre range – itself born from Bridgestone’s long association with Formula One racing – empowering motorsports enthusiasts to remain in control at speed. Emilio Tiberio, COO & CTO, Bridgestone EMIA, said, “The Potenza Race adds an additional dimension to our iconic Potenza range. The existing Potenza Sport has been an incredible success since it launched, and now the Potenza Race takes things a step further by offering unrivalled performance to track day enthusiasts. Many have already seen and experienced what the Potenza Race original fitments can do on the Lamborghini Huracán STO and Seat Leon Cupra – we’re thrilled to be bringing it to the replacement market for more drivers.” 

Developed and manufactured in Europe, Bridgestone’s new Potenza Race will be available in 13 popular sizes between 17 and 20 inches from June 2022, supporting the hot hatchbacks and sportscars most commonly found attending track days.  

Benefitting from this heritage and the expertise gained during the development of Potenza Race OE fitments for the Lamborghini Huracán STO and SEAT Leon Cupra hot hatchback, along with the Huracán STO Tecnica supercar launched recently, the Potenza Race is Bridgestone’s first-ever dedicated replacement tyre for track days. 

The new Potenza Race completes Bridgestone’s ultra-high performance tyre line-up, providing a track-focussed tyre ideal for driving enthusiasts, the release said. 

According to tests carried out by independent TÜV SÜD, the Bridgestone Potenza Race posts the best lap times ahead of its main competitors on the track. The Bridgestone Potenza Race tyre also offers the shortest braking distance on a dry surface. 

The tread design applies an asymmetric pattern, with differentiation between the outside and inside of the tyre to maximise cornering power and braking potential while still guaranteeing suitable usage on wet roads, it said. 

Asymmetric wall angles on the Potenza Race tyre further increase lateral stiffness and reduce block deformation, and a special rear tread pattern with an increased shoulder rib provides maximum dry performance with optimised braking and block stiffness. 

The Potenza Race also incorporates a sporty profile shape, helping to increase the contact area and maximise braking potential. An optimised contact patch helps to improve steering feel and controllability, increasing driver confidence. 

It also benefits from a new compound, with innovative mixing to improve chemical reaction control, balancing the reinforcing mechanism and rolling resistance. The result is an optimised formula for enhanced dry performance, with high stiffness that boosts dry cornering and straight-line stability. 

The new Potenza Race has been developed using Bridgestone’s Virtual Tyre Development technology. This enables a digital version of an in-development tyre to be created and tested, helping Bridgestone to predict how a tyre will perform in different conditions before physically building prototypes. As a result, Bridgestone can test far more variants in a virtual world, which cuts tyre development time by up to 50 per cent and delivers a host of environmental benefits including a reduction in raw material consumption due to the need for fewer prototype tyres and tests, the release added.

India is losing more than 425.7 million litres of petrol worth over INR 45 billion each year because of underinflated tyres, according to a survey by the Automotive Tyre Manufacturers' Association (ATMA), which warned that poor tyre maintenance is also increasing road safety risks.

The findings come as higher crude oil prices and the continuing West Asia conflict put additional pressure on fuel costs, making fuel efficiency an increasingly important concern for motorists.

The tyre health survey, conducted by the Indian Tyre Technical Advisory Committee (ITTAC), ATMA's technical arm, found that a significant proportion of passenger vehicles on Indian roads are operating with tyre pressures below manufacturers' recommended levels.

More than 130,000 passenger vehicle tyres, including those fitted to two-wheelers, have been inspected across India over the past few years, including nearly 100,000 during the past year. The survey found that 32 percent of tyres had air pressure more than 20 percent below the recommended level, while a further 21 percent were between 10 percent and 20 percent below the recommended pressure.

According to international studies cited by ATMA, every one PSI reduction in tyre pressure reduces fuel efficiency by about 0.2 percent. Based on the survey findings, the association estimates that underinflated tyres account for fuel efficiency losses equivalent to around 0.75 percent of India's total fuel consumption by vehicles.

With India's annual petrol consumption estimated at 56.77 billion litres, almost all of which is used by passenger vehicles, including two-wheelers, this equates to an annual loss of around 425.7m litres of petrol. At current retail fuel prices, the value of the wasted fuel exceeds INR 45 billion annually.

ATMA said the estimate covers only petrol consumption and excludes diesel-, CNG- and LPG-powered passenger vehicles, suggesting that the overall national fuel loss is likely to be even higher.

The association said the fuel loss assumes greater significance because India imports more than 80 percent of its crude oil requirements. Avoidable fuel consumption not only increases costs for consumers but also adds to the country's oil import bill and foreign exchange outgo.

Renji Issac, chairman of ITTAC, said: "The survey highlights a hidden but significant drain on both household budgets and the national economy. At a time when fuel prices have gone up owing to West Asia conflict, maintaining the correct tyre pressure is one of the simplest and most effective ways to improve fuel efficiency and reduce fuel expenses. The low inflation pressure also increases the emissions resulting in more atmospheric pollution."

Apart from the economic impact, the association said underinflated tyres generate excessive heat, reduce vehicle handling and braking performance, increase stopping distances and make tyres more susceptible to damage or sudden failure, particularly during high-speed driving. Low tyre pressure also accelerates uneven tyre wear, shortening tyre life and increasing replacement costs.

Sudershan S Gusain, chairman of ATMA's Safety Awareness Group, said: "Apart from the economic cost, low tyre pressure also has serious safety implications. Tyres operating below the recommended pressure generate excessive heat, adversely affect vehicle handling and braking performance, increase stopping distances and are more susceptible to tyre damage or sudden failure, particularly during high-speed travel. Low tyre pressure also accelerates uneven tyre wear, reducing tyre life and increasing replacement costs."

ATMA said a tyre pressure check takes only a few minutes but can improve fuel efficiency, extend tyre life, reduce emissions and enhance road safety. The association advised motorists to check tyre pressure every fortnight, preferably when tyres are cold, and to maintain the pressure recommended by the vehicle manufacturer.

The association also urged electric vehicle owners to pay attention to tyre pressure monitoring system (TPMS) alerts. While most EVs display tyre pressure on the dashboard, these warnings are often ignored because drivers make fewer visits to fuel stations. Maintaining the correct tyre pressure improves vehicle range, tyre life, safety and environmental performance, ATMA said.
