Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What's the difference between summer and winter tyres for a Porsche 911?
Winter tyres use a different rubber compound that stays flexible below 7°C, plus deeper sipes for snow and slush grip. For UK Porsche 911 drivers in colder regions, dedicated winters or 3PMSF all-seasons can be worthwhile.
What pressure should the Porsche 911 run?
The correct pressure for your Porsche 911 is on the placard inside the driver's door frame and in the handbook — not on the tyre itself. Pressure varies by load and trim. Check cold once a month.
What's the legal tread depth for a Porsche 911 in the UK?
The UK legal minimum tread depth is 1.6mm across the central three-quarters of the tyre. Many tyre safety bodies recommend replacing at 3mm for better wet weather safety on the Porsche 911.
Why does the Porsche 911 have different tyre sizes by year?
The Porsche 911 has had 10 UK-market generations. Each generation uses a different platform and wheel options, so tyre sizes are not interchangeable across the model's history. Pick the year-correct generation page for accurate fitment data.
Is wheel alignment important after fitting new 911 tyres?
Yes — a wheel alignment check after fitting new tyres on the Porsche 911 preserves tread life and handling. Most UK fitters offer a quick alignment check; major adjustments (camber/caster) require a four-wheel laser machine.
