BYD SEALION 5 DM-i tires, wheels and TPMS
Tire size, pressure and TPMS guidance from the owner handbook.
Skip to content
What is confirmed
The handbook technical-data table lists 225/60R18 tires and 250 kPa tire pressure, and the TPMS chapter explains that the system monitors tire pressure in real time, indicates low pressure or sensor/system faults and asks owners to check pressure immediately when warned.
Scope and safety boundaries
Do not inflate visibly damaged tires or ignore repeated TPMS faults. Wheel/tire fitment, TPMS sensors and brake clearance require VIN confirmation.

Frequently asked questions
Is this official BYD content?
No. It is an AutoTechHelp source-backed owner help page. Official BYD sources are cited and scoped by market.
Which public slug is used?
AutoTechHelp keeps the existing public URL slug byd-sealion-5-dmi. The prompt spelling byd-sealion-5-dm-i is treated as an alias.
Does this apply to SEALION 6 DM-i, SEAL U DM-i or Song Plus DM-i?
No. SEALION 5 DM-i facts are not merged with related BYD models unless an official source proves exact compatibility.
Was an owner handbook found?
Yes. A BYD New Zealand owners-manual page provides a direct SEALION 5 owner handbook PDF, extracted for owner-safe chapters, maintenance and warning lights.
Are EU and UK manuals complete?
Not yet. EU, UK and Romania owner-manual hubs are stored as official discovery sources while direct regional manual assets still need extraction.
Are DTC codes published?
No. Model-specific DTC/error-code pages remain blocked until an official diagnostic or service source confirms exact codes.
Can I use the maintenance schedule globally?
Use it as a source-scoped New Zealand/Australia RHD handbook schedule and confirm your own market by VIN, local manual or BYD service.
Is this a repair guide?
No. HV battery, hybrid system, brakes, steering, airbags, ADAS, fuel system, wiring, towing/recovery and repair procedures remain service-only.
Can imported-car owners use this?
Use it as a source map. Before applying any fact, confirm market, VIN, trim, battery, software and dealer support.
How often should sources be rechecked?
This seed stores checked dates and review tasks. Dynamic manuals, warranty pages and recall sources should be rechecked as BYD publishes updates.
