Detailed tire and wheel breakdown for the 2018 Peugeot 508

Tire geometry — 235/45R18

The 235/45R18 fitted to the 2018 Peugeot 508 has a section width of 235mm and an aspect ratio of 45%, mounted on a 18-inch rim. That gives a sidewall height of 105.8mm (4.16") and an overall outside diameter of 668.7mm (26.33"). At highway speed this tire completes roughly 476 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.

Plus-sizing window

If you want to upsize wheels on the 2018 Peugeot 508 while keeping the speedometer accurate, target a 245/38R19 (plus-one). For a softer ride or winter setup, a 225/53R17 (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 2018 Peugeot 508 uses a 5x108 bolt pattern with a 65.1mm hub bore. Safe rim width range for the OEM tire is 7.5J – 8.5J, and offsets in the ET37 – ET47 window will clear suspension and fender without rubbing on most setups.

Tire pressure guidance

Manufacturer-recommended cold tire pressure for the 2018 Peugeot 508 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%.
