Porsche 911 and Taycan 4S 305/30R21 Michelin PS4S N1 Adelaide
Quick answer
This workshop visit brought together a Porsche 911 Coupe, 992 generation and a Porsche Taycan 4S for tyre replacement and four-wheel alignment. The supplied tyre specification was 305/30R21 Michelin Pilot Sport 4S (N1).
The N1 marking matters because it identifies a Porsche-approved version of the tyre. For Porsche vehicles, choosing the correct Porsche-approved marking helps keep the tyre specification aligned with Porsche's intended grip, load, steering, stability-control and vehicle setup requirements.

Why N1 is important
N1 is a Porsche homologation mark used on tyres approved for Porsche applications. A Michelin Pilot Sport 4S with a Porsche N-marking is not just a generic tyre label; it indicates that the tyre version has been developed and approved for Porsche requirements.
That matters on cars like the Porsche 911 and Taycan 4S because the tyre affects braking feel, steering response, traction control behaviour, wet grip, load handling and tyre wear. On the Taycan 4S, the EV weight and instant torque make load rating, pressure and approved specification especially important. On the 911, the rear tyre contact patch is central to traction and stability.
Fitment notes
The supplied tyre size is 305/30R21 Michelin Pilot Sport 4S (N1). Exact live Shopify availability should be confirmed before ordering, so this article uses Michelin, Pilot Sport 4S, Porsche N1, 305/30R21 search and alignment links rather than inventing an unavailable exact SKU page.
Before fitting, confirm the tyre placard, axle position, load index, speed rating, OE marking, production date, tyre pressure settings and whether the tyres are being replaced as a matched axle pair or as part of a full set.
Why four-wheel alignment matters
Four-wheel alignment is recommended after fitting performance tyres because it helps protect tyre life, confirms the vehicle tracks straight and gives the workshop a clean baseline after the new Michelin PS4S N1 tyres are installed. With wide 305/30R21 tyres, incorrect toe or camber can create expensive shoulder wear quickly.

FAQ
What are the full vehicle names?
The vehicles are written as Porsche 911 Coupe, 992 generation, and Porsche Taycan 4S. The image does not safely confirm the exact 911 trim, so this article does not claim Carrera, GTS, Turbo or another variant.
What tyre was fitted?
The supplied tyre specification was 305/30R21 Michelin Pilot Sport 4S (N1).
Why does N1 matter on Porsche tyres?
N1 is a Porsche-approved tyre marking. For Porsche vehicles, matching the correct approved marking helps keep the tyre specification aligned with Porsche's intended vehicle setup.
Should a Porsche get alignment after new Michelin PS4S N1 tyres?
Yes. Four-wheel alignment helps protect tyre life, steering feel, braking stability and straight-line tracking after new performance tyres are fitted.
