When it comes to driving a Porsche, an exhilarating experience is often underscored by the performance of its tyres. The Porsche 928, is an iconic sports car with a reputation for balance and style and is one such vehicle where tyre selection significantly influences performance and handling. This article will explore tyre comparisons focusing on performance, price, and the N-ratings that indicate suitability for the Porsche 928. Whether you're seeking to maintain your cherished 928 or contemplating an upgrade, understanding tyre dynamics is important.
TL:DR – The proper selection of tyres for your Porsche 928 can alter your driving experience considerably, emphasising performance, safety, and handling. N-rated tyres are specifically tested and designed for Porsche vehicles and have specific charcteristics including a reinforced radial structure along with more rigid sidewalls that enhance performance with Porsche vehicles. Given the various options available, owners are encouraged to consider value versus performance in their tyre selection while ensuring correct tyre pressure is maintained.
Understanding N-ratings and their significance
The N-rating system for tyres was developed by Porsche as a quality assurance measure to ensure that tyres used on their vehicles meet specific performance and safety standards. This system indicates that a tyre has passed rigorous testing under conditions relevant to the Porsche driving experience. Tyres marked with an "N," followed by a number—such as N0, N1, etc.—indicate the version and the extent of enhancements made to the original tyre design. Higher numbers generally correlate with newer specifications and improved performance characteristics.
This is particularly critical for owners of the Porsche 928, where performance and stability are key considerations. It is important to use tyres with the same N-rating across all four corners of the vehicle. This uniformity ensures consistent handling, improved road feedback, and predictable driving dynamics. Disparities in tyre performance caused by differing N-ratings can lead to unpredictable handling characteristics, which can be especially dangerous in high-speed scenarios or track days.
Porsche recommend only 'N' rated Bridgestone, Michelin, Continental and Pirelli tyres for the Porsche 928.
Price-performance considerations
Tyre purchases can often feel daunting, especially considering the wide price range and performance levels available on the market. Selecting a tyre for the Porsche 928 is not just a financial decision but one that directly impacts performance and handling. In the UK market, one can find approved tyres ranging between competitive prices up to premium options, often dictated by brand reputation and quality.
At the premium end Michelin has historically been a preferred choice among Porsche enthusiasts, given its long-standing OEM (Original Equipment Manufacturer) agreements with Porsche. Models like the Michelin Pilot Sport 4 S offer a commendable balance between price and performance, boasting reliability and first rate handling and braking in both wet and dry conditions. However, the financial outlay is higher wthan a budget tyre.
On the flip side, there are economically-minded choices available, such as performance brands renowned for their value propositions, which may also cater to the Porsche 928. While these alternative brands may not carry the Porsche approval markings, they can offer performance-centric solutions at a more approachable price point. Nevertheless, it is imperative to weigh the performance factors alongside the pricing structure, as inferior tyres can lead to increased wear leading to more frequent replacement.
Tyre pressure: critical for performance
Maintaining the correct tyre pressure in your Porsche 928 is critical for ensuring optimal performance and longevity. Tyres that are under-inflated can exhibit poor handling characteristics, excessive wear, and an increased likelihood of blowouts. Conversely, over-inflated tyres can reduce the contact patch with the road, causing diminished grip and possibly leading to a jittery driving experience. The ideal tyre pressure information can often be found printed on the inside of the driver's side door frame or within user manuals.
Maintaining the correct pressures not only improves handling but also optimises fuel efficiency—a vital consideration given the slightly thirsty V8 in the 928. It is recommended to check the tyre pressures when cold as performance can fluctuate once the tyres heat up, impacting their shape and pressure reading.
Many Porsche enthusiasts advocate the use of digital pressure gauges for precision. Older manual gauges can often yield imprecise readings, which can lead to unnecessary fluctuations in driving experience. Routine checks should be integrated into the maintenance schedule as part of ensuring the vehicle performs at its peak.
Comparing tyres online: finding value
Taking advantage of online capabilities can greatly enhance your tyre shopping experience, especially for a niche vehicle like the Porsche 928.
Specialists such as Design 911, a friendly bunch who fitted new wheels and tyres for my Silver 928 S4 Sport years ago, might have tyres or tyre and wheel sets compatible with the Porsche 928. Remember that although many have been successful, 18 inch wheels are not supported by Porsche for the Porsche 928!
Websites such as mytyres - the home of low price tyres for cars in the UK have emerged to assist drivers in sourcing tyres that meet their specific needs, offering comparable prices and various retailer options. This armchair shopping experience can save both time and money while providing extensive insights into performance reviews from fellow Porsche owners.

A well-fitted tyre can make all the difference in the motoring experience, so assess local system capabilities as part of your online purchasing journey.
Another key advantage of online comparison tools is access to user reviews. Existing Porsche 928 tyre reviews can provide invaluable insight into the real-world performance of various brands, shedding light on longevity, grip across weather conditions, and overall satisfaction. Such community input is often highlighted in customer feedback sections, enabling cherished discussions amongst vehicle enthusiasts.
Winter, summer, and all-season tyres
Tyres are not a one-size-fits-all proposition; the seasonal transitions significantly influence their performance. For the Porsche 928, selecting the right tyre type for the driving season is essential. Choosing between summer tyres, winter tyres, or all-season options can affect not just performance, but also safety and the overall driving experience.
Summer tyres are purposely designed to provide superior grip and handling in warmer conditions, featuring a softer compound that enhances traction and responsiveness. They are less effective in cold conditions, and attempting to drive them in snow or ice can lead to hazardous situations.
Conversely, winter tyres feature a tread pattern specifically designed for improved traction in snow and slush. In addition, their rubber compounds are engineered to remain flexible at lower temperatures enhancing grip. For those who do not wish to swap tyres seasonally, all-season tyres provide a compromise. While they may not perform as efficiently as dedicated summer or winter tyres, they do provide versatility and convenience throughout most driving conditions.
In the UK, typically, people only choose summer tyres. Most of our Porsche 928's are tucked away for a sleep after our annual meeting until the Spring.
