Scope checked: 26 October 2026. China battery examples use the official configuration snapshots retrieved on 25 October 2026. Match the original market, model year, hardware and software before applying a procedure.
Use the vehicle’s own pressure reference
There is no single correct pressure for every 001, 7X, X or 009. Read the vehicle’s pressure placard and matching manual, noting wheel size, front/rear values and loading conditions. The maximum pressure moulded into a tyre sidewall is not the car’s recommended operating pressure. If the label is missing or a wheel conversion has been made, obtain a documented specification before adjustment.
- Photograph the placard and record its units with the values.
- Check whether normal load and full load use different recommendations.
Check cold tyres and compare readings
Measure with a suitable gauge before driving, under the cold-tyre conditions in the manual, and compare all wheels. Do not let air out of a hot tyre simply to reach a cold reference. Temperature changes can alter readings; a persistent difference at one wheel still needs investigation. TPMS supports monitoring but does not replace a physical condition and pressure check.
- For unit conversion, 1 bar equals 100 kPa and approximately 14.5 psi.
- Record pressure, temperature and time to compare the same conditions later.
Match more than rim diameter
A replacement tyre or wheel needs more than an attractive size. Confirm approved dimensions, load and speed ratings, wheel width and offset, fixings, brake clearance and sensor compatibility with a competent tyre specialist. An EV label on the product does not prove suitability for a heavy MPV or a particular AWD version. Front and rear fitments may differ, so check each axle separately.
- Ask for written confirmation of the exact tyre and wheel combination.
- Check tyre direction and inside/outside markings during professional fitting.
Treat regional sizes as examples, not universal fitment
Macao’s approval record for a specific 2025 7X RWD 75 kWh lists 255/50-19, 265/45-20 and 265/40-21 tyre options. It does not establish pressure, wheel approval or interchangeability for every Chinese or overseas 7X. Nor does a 7X approval establish a fitment for 009. Use the VIN, local approval documents and actual fitted equipment to resolve any discrepancy.
- Keep the original fitment record when changing wheel size.
- Before winter-wheel purchase, confirm brake clearance and TPMS requirements for the exact vehicle.
Respond to a pressure warning logically
If a warning appears, stop somewhere safe and inspect for visible damage or a deflated tyre before continuing. An apparently normal screen value does not rule out a puncture or sensor problem. Repeated loss at one corner requires tyre inspection; several missing readings after wheel replacement suggest a different enquiry about sensors or configuration. Do not reset a warning to hide unresolved pressure loss.
- For vibration, sidewall damage or rapid pressure loss, stop driving and seek assistance.
- Ask the fitter to confirm sensor compatibility and the documented learning procedure; do not invent a universal reset sequence.
Prepare for punctures and wheel work
Check what your car actually carries: repair kit, compressor or an approved spare arrangement. Sealant has limits and an expiry date; a damaged sidewall is not an ordinary small tread puncture. Follow the kit and vehicle instructions and tell the repairer if sealant was used. Lifting points, tightening specifications and air-suspension preparation must come from the exact manual.
- Inspect kit condition before a remote journey and confirm roadside contact details.
- Record any wheel impact, repair and alignment check in the service history.
