Detailed tire and wheel breakdown for the 2017 Infiniti Q50
Tire geometry â 245/40R19
The 245/40R19 fitted to the 2017 Infiniti Q50 has a section width of 245mm and an aspect ratio of 40%, mounted on a 19-inch rim. That gives a sidewall height of 98.0mm (3.86") and an overall outside diameter of 678.6mm (26.72"). At highway speed this tire completes roughly 469 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2017 Infiniti Q50 while keeping the speedometer accurate, target a 255/33R20 (plus-one). For a softer ride or winter setup, a 235/47R18 (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 2017 Infiniti Q50 uses a 5x114.3 bolt pattern with a 66.1mm hub bore. Safe rim width range for the OEM tire is 8.0J â 9.0J, and offsets in the ET35 â ET45 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2017 Infiniti Q50 ships staggered: 245/40R19 up front and 265/35R19 on the rear. That is a 265mm vs 245mm 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 2017 Infiniti Q50 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%.
