Porsche Approved Tyres
Production tires that have passed all of the tests and received the engineering department’s release can be branded with an N-specification. The N-specification brandings include: N-0 (N-zero), N-1, N-2, N-3, N-4 or N-5. These markings on a tire’s sidewall clearly identify them as approved by Porsche for their vehicles.
The N-0 marking is assigned to the first approved version of a tire design. As that design is refined externally or internally, the later significant evolutions will result in a new generation of the tire to be branded with N-1, N-2, N-3, etc., in succession. When a completely new tire design is approved, it receives the N-0 branding and the succession begins again.
It is recommended that only matching tires be used on Porsche vehicles. Since many Porsche vehicles are fitted with differently sized tires on their front and rear axles, this means matching the tire make, tire type and N-specification. If a vehicle was originally delivered with N-specification tires that have been discontinued and are no longer available, it is recommended to change all four tires to a higher numeric N-specification design appropriate for that vehicle. Mixed tire types are not recommended.
It is also important to know that while Porsche N-specification tires have been fine tuned to meet the specific performance needs of Porsche vehicles, the tire manufacturers may also build other tires featuring the same name, size and speed rating as the N-specification tires for non-Porsche applications. These tires may not be branded with the Porsche N-specification because they do not share the same internal construction and/or tread compound ingredients as the N-specification tires. Using tires that are not N-specific is not recommended and mixing them with other N-specification tires again is not recommended.
Here endeth the lesson, and with the high speed driving that Hong Kong offers, not a lot ?, you will probably never find out what these tyres can do for you, if you’re a purist and a stickler for the book then stay with ‘N’ rated, otherwise a decent high speed rated tyre will suffice for the red light racing !, I was going to include a list of available ‘N’ rated tyres but as it keeps changing and now A/T tyres to consider I decided to give it a miss, if you need any help on that one just call.
