Browse the photos below to see how different tyre and wheel brands look at this combination.
Barely 4mm separates this 225 from the 9 inch rim's 229mm width, a whisper of stretch that mostly smooths the sidewall line. The 40 profile holds 90mm of nominal height on the 18. E92 BMWs and Audi S-line cars left the factory on near-identical geometry.
