Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What should Audi RS 4 drivers know about UK potholes?
UK road conditions are tough on tyres. Check sidewall bulges, cuts and tread depth regularly — especially on the inside edge, which often wears unevenly. A 20p coin gives a quick legal-tread check.
Where should I check the original tyre size for my Audi RS 4?
Look in three places: (1) the sidewall of the existing tyre, (2) the placard inside the driver's door frame, and (3) the vehicle handbook. The driver's door placard is the official OEM specification, and the sidewall confirms what's fitted now.
What wet grip should I look for on the Audi RS 4?
For UK driving conditions, prioritise an EU tyre label wet-grip rating of A or B. Wet grip directly affects braking distance — the gap between A and E ratings can be more than a car length at 50 mph.
Are OEM tyres still fitted to new Audi RS 4 cars?
New UK Audi RS 4 cars leave the factory with original-equipment (OEM) tyres specified by Audi. When replacing, you can stay on the same OEM brand or move to an alternative provided the size, load index and speed rating match.
Are premium-brand tyres worth it on a Audi RS 4?
On a Audi RS 4, premium tyre brands (Michelin, Continental, Bridgestone, Pirelli, Goodyear) typically deliver longer tread life, better wet grip and quieter rolling. The cost difference is usually recouped over the tyre's life.
