Detailed tire and wheel breakdown for the 2026 Mercedes-Benz E-Class
Tire geometry â 245/45R19
The 245/45R19 fitted to the 2026 Mercedes-Benz E-Class has a section width of 245mm and an aspect ratio of 45%, mounted on a 19-inch rim. That gives a sidewall height of 110.3mm (4.34") and an overall outside diameter of 703.1mm (27.68"). At highway speed this tire completes roughly 453 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2026 Mercedes-Benz E-Class while keeping the speedometer accurate, target a 255/38R20 (plus-one). For a softer ride or winter setup, a 235/52R18 (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 2026 Mercedes-Benz E-Class uses a 5x112 bolt pattern with a 66.6mm hub bore. Safe rim width range for the OEM tire is 8.0J â 9.0J, and offsets in the ET30 â ET40 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2026 Mercedes-Benz E-Class ships staggered: 245/45R19 up front and 275/40R19 on the rear. That is a 275mm 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 2026 Mercedes-Benz E-Class 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%.
