How to check the correct cold tyre pressure on a BYD ATTO 3

China-market owner report

In a discussion dated 2024-06-07, the linked China-market report raised this issue: An owner asked which pressure to use after seeing a high delivery pressure and receiving conflicting advice. This is an individual account, not a confirmed diagnosis or failure-rate finding. The steps below use the export handbook.

Checks to make while safely parked

1. 1Read your vehicle labelFind the driver-door-frame pressure label and identify the fitted tyre specification and any relevant load condition. Keep units consistent between the label, gauge and dashboard.
2. 2Let the tyres coolThe manual defines a cold measurement after at least three hours stopped. If a short journey is unavoidable, its allowance is no more than 1.6 km before measurement.
3. 3Measure and inspect all fourUse a reliable gauge and check for damage, embedded objects or unusual wear as you work. A falling tyre needs investigation rather than repeated topping up alone.
4. 4Adjust to the documented valueSet the cold pressure to the label, refit valve caps and record the reading. Do not use another owner’s preferred pressure as a comfort or range modification.

Check the result and know when to stop

After driving, pressure can legitimately read higher than the cold value. BYD warns against deflating warm tyres to meet the cold target, because they can then be low after cooling. If the tyre specification has changed, have the fitment and required pressure checked professionally.
