Wheel fitment specs
The 2025 BYD Atto 3 uses a 5x114.3 bolt pattern with a 60.1mm hub bore. Safe rim width range for the OEM tire is 6.5J â 7.5J, and offsets in the ET35 â ET45 window will clear suspension and fender without rubbing on most setups.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2025 BYD Atto 3 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%.
