Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What tyre choices suit a Porsche Cayenne towing a caravan?
For towing on the Porsche Cayenne, prioritise load index, sidewall stiffness and a strong wet grip rating. Some tyre makers offer "XL" (extra-load) versions which are better suited to high-load and tow scenarios.
Is wheel alignment important after fitting new Cayenne tyres?
Yes — a wheel alignment check after fitting new tyres on the Porsche Cayenne preserves tread life and handling. Most UK fitters offer a quick alignment check; major adjustments (camber/caster) require a four-wheel laser machine.
What's the legal tread depth for a Porsche Cayenne 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 Cayenne.
What pressure should the Porsche Cayenne run?
The correct pressure for your Porsche Cayenne 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.
Where do I find the load index for Porsche Cayenne tyres?
Load index appears at the end of the tyre size, just before the speed rating — e.g. 91V means load index 91, speed V. Match or exceed the original load index shown on the door placard of your Porsche Cayenne.
