BMW 120i Tyre Size Guide
Wheel Specs, PCD, Centre Bore, Torque & Runflat Tyres
The BMW 120i is a premium variant in the 1 Series lineup, offering enhanced performance and often equipped with larger wheels and staggered tyre setups. This makes tyre selection especially important for:

Ride comfort

Noise levels

Fuel efficiency
Many BMW 120i models are fitted with runflat tyres (RFT) from factory.
At Autosport Tyreworld, we specialise in BMW tyre fitment, runflat replacements and performance upgrades.
