Detailed tire and wheel breakdown for the 2015 Smart Fortwo
Tire geometry â 185/50R16
The 185/50R16 fitted to the 2015 Smart Fortwo has a section width of 185mm and an aspect ratio of 50%, mounted on a 16-inch rim. That gives a sidewall height of 92.5mm (3.64") and an overall outside diameter of 591.4mm (23.28"). At highway speed this tire completes roughly 538 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2015 Smart Fortwo while keeping the speedometer accurate, target a 195/41R17 (plus-one). For a softer ride or winter setup, a 175/60R15 (minus-one) keeps the overall diameter within Âą3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.
Wheel fitment specs
The 2015 Smart Fortwo uses a 4x100 bolt pattern with a 60.1mm hub bore. Safe rim width range for the OEM tire is 5.5J â 6.5J, and offsets in the ET39 â ET49 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2015 Smart Fortwo ships staggered: 185/50R16 up front and 205/45R16 on the rear. That is a 205mm vs 185mm width difference â do not rotate front-to-rear, and replace tires in axle pairs to keep ABS and traction control balanced.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2015 Smart Fortwo is printed on the driver-side door jamb sticker â 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%.
