The 245/45R20 fitted to the 2019 BYD Tang has a section width of 245mm and an aspect ratio of 45%, mounted on a 20-inch rim. That gives a sidewall height of 110.3mm (4.34") and an overall outside diameter of 728.5mm (28.68").

For a softer ride or winter setup, a 235/52R19 (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 2019 BYD Tang uses a 5x114.3 bolt pattern with a 60.1mm hub bore. Safe rim width range for the OEM tire is 7.5J â 8.5J, 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 2019 BYD Tang 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%.
