Which Cars Use 225/45 R17?

The default 17-inch size on German saloons and estates: the BMW 3 Series (in run-flat form), Audi A4, Mercedes C-Class, Volkswagen Passat, Skoda Superb, Ford Mondeo, Vauxhall Insignia, Volvo S60 and Lexus IS, plus the Golf GTI Mk5 and Mk6 and many Golf, A3 and Leon models on 17-inch options.

Wheel options change everything, so a model on this list may run a different size on its larger alloys. The door-jamb label is the reference; we will check it by registration if you prefer.

What 225/45 R17 Means

Three figures, three facts. 225: the tyre is 225 mm across the tread. 45: the sidewall stands 45 per cent of that width, roughly 101 mm. R17: radial construction on a 17-inch wheel. Multiply it out and the tyre is about 634 mm tall overall, which is why a different profile on the same rim is not a like-for-like swap: it changes the gearing, the speedometer and the space in the arch.

Load and Speed Ratings on 225/45 R17

Markings on this size run to 91W, 91Y, 94W XL and 94Y XL. Read them as a floor set by the manufacturer for your car: at least this much load capacity, at least this speed capability. Above is fine; below is not. Where the label calls for the higher load index that means an XL tyre, and the pressures on the label go with it. Ask us and we will read the requirement off your registration.

Good to know

Do I need run-flat 225/45 R17 tyres on my BMW? If the car came on run-flats and has no spare or repair kit, replacing like for like is the safe choice. Switching to conventional tyres is possible but leaves you with no get-you-home option; we explain both routes before you decide.

What to Watch For on This Size

This size carries a lot of company-car mileage, which makes wear rate and rolling resistance worth weighing alongside grip; a good touring tyre here will outlast a performance pattern by a wide margin on the A11 commute. Front-wheel-drive saloons wear the fronts faster; rear-drive BMWs and Mercedes wear the rears, and BMW fitments are usually run-flat with a star marking. XL versions are common and often required on heavier diesels and estates.

Brands Available in 225/45 R17

Comprehensive: Michelin Primacy and Pilot Sport, Continental PremiumContact, Goodyear EfficientGrip and Eagle F1, Bridgestone Turanza and Potenza, Pirelli Cinturato, with Hankook, Kumho, Falken, Yokohama, Nexen, Uniroyal and Vredestein in the middle and every budget brand at the bottom.

The right tier depends on the car, the mileage and how long you will keep it; our cheap tyres guide sets out when budget makes sense and when it does not. Every option is quoted with its EU label, and every brand has a page in the brand directory.
