Detailed tire and wheel breakdown for the 2025 Karma Automotive GS-6
Tire geometry â 245/40R21
The 245/40R21 fitted to the 2025 Karma Automotive GS-6 has a section width of 245mm and an aspect ratio of 40%, mounted on a 21-inch rim. That gives a sidewall height of 98.0mm (3.86") and an overall outside diameter of 729.4mm (28.72"). At highway speed this tire completes roughly 436 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2025 Karma Automotive GS-6 while keeping the speedometer accurate, target a 255/33R22 (plus-one). For a softer ride or winter setup, a 235/47R20 (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 2025 Karma Automotive GS-6 uses a 5x120 bolt pattern with a 66.9mm hub bore. Safe rim width range for the OEM tire is 8.0J â 9.0J, and offsets in the ET40 â ET50 window will clear suspension and fender without rubbing on most setups.
Staggered setup notes
The 2025 Karma Automotive GS-6 ships staggered: 245/40R21 up front and 265/40R21 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 2025 Karma Automotive GS-6 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%.
