Detailed tire and wheel breakdown for the 2019 Ford Focus

Tire geometry — 235/40R18

The 235/40R18 fitted to the 2019 Ford Focus has a section width of 235mm and an aspect ratio of 40%, mounted on a 18-inch rim. That gives a sidewall height of 94.0mm (3.70") and an overall outside diameter of 645.2mm (25.40"). At highway speed this tire completes roughly 493 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.

Plus-sizing window

If you want to upsize wheels on the 2019 Ford Focus while keeping the speedometer accurate, target a 245/33R19 (plus-one). For a softer ride or winter setup, a 225/47R17 (minus-one) keeps the overall diameter within ±3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.

Wheel fitment specs

The 2019 Ford Focus uses a 5x108 bolt pattern with a 63.4mm hub bore. Safe rim width range for the OEM tire is 7.5J – 8.5J, and offsets in the ET50 – ET60 window will clear suspension and fender without rubbing on most setups.

Tire pressure guidance

Manufacturer-recommended cold tire pressure for the 2019 Ford Focus is printed on the driver-side door jamb sticker — always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
