2025 Guide for BYD Electric Vehicles: Tire Wear, Rotation, Pressures, Alignment, and TPMS. Practical Tips for Dolphin and Seal, Tables, Costs, and CTAs for EV-Ready Tires.
✅ 2025 Overview: Why EVs Are Eating More Tires
On electric vehicles like the BYD Dolphin and BYD Seal , tire wear is influenced by four key factors: battery weight, instantaneous torque , energy recovery ( regen ), and often overlooked pressures . Choosing EV-ready tires and a targeted rotation and alignment plan reduces costs and noise while improving range.
- Weight : greater load → more stressed shoulders and edge wear when driving in urban areas.
- Torque : full acceleration = premature front (FWD) or rear (RWD/AWD) axle wear.
- Regeneration : in the city it can “polish” the brake discs but stresses the tread when decelerating.
- Pressures : 0.2–0.3 bar less reduces range and regular wear; excess causes central fuel consumption.

⚠️ Typical wear and tear on EVs (causes and quick fixes)
1) Worn shoulders / serrations
- Symptoms: Saw-like notches, slight vibrations, humming noise between 60–90 km/h.
- Common causes: Out-of-spec toe/cam, late rotations, tired shock absorbers, aggressive regen driving.
- Solutions: Rotation every 8–10,000 km, 3D alignment check, check cold pressures; evaluate EV-ready tires with anti-scalloping compounds.
2) Central wear / high pressure
- Symptoms: Tread depth lower in the center.
- Cause: Chronically high pressures (light load + highway).
- Remedy: Observe the pressure plate (driver's side door pillar). Adjust between Eco and full load if applicable. Measure cold.
3) Tread noise / “EV hum”
- Symptoms: Constant buzzing that increases with speed, even on smooth asphalt.
- Causes: irregularly worn pattern, compound not optimized for EV, bearings ok but “toothy” tires.
- Solutions: regular rotations, inversion on symmetrical trains, choice of tires with sound-absorbing foam and low rolling resistance.
4) Loss of grip on wet surfaces
- Symptoms: lengthening of spaces, often active ESC/TC.
- Causes: tread depth < 3.5 mm , hardened compound, incorrect pressure.
- Solutions: replace below 3mm (practical advice), check DOT/age, check seasonal pressures.
5) Tire mix and traction (FWD/RWD/AWD)
- Dolphin (typically FWD): severe front wear → frequent forward/reverse rotation .
- Seal (often RWD/AWD): rear most stressed → evaluate cross-rotation if pattern allows it.
🔁 Rotations & 📈 Pressures (BYD Dolphin / Seal)
Rotation frequency
- Urban/stop&go use : every 8–10,000 km or 6–8 months.
- Mixed/motorway : every 10–12,000 km .
- After major impacts/potholes or vibrations, check the trim and rotation early.
Recommended patterns
- Same rolling direction (asymmetric non‑directional): X pattern (front right ↔ rear left) + (front left ↔ rear right).
- Directional (arrow): forward/backward on the same side; reversal only when disassembled and reassembled on the rim.
- AWD: Keep axle differences < 2mm.
“Guide” pressures for real-world use
Important note: Always refer to the BYD pressure plate on the door jamb. The following are operating guidelines for daily use (cold):
| Model | Common measures* | City / mixed use | Highway / cargo | Notes |
|---|---|---|---|---|
| BYD Dolphin | 16–17” (e.g. 205/55R16 · 205/50R17) | follow vehicle license plate (typically ~ 2.4–2.6 bar ) | possible +0.1–0.2 bar if at full load | Cold measurement, recalibrate TPMS. |
| BYD Seal | 18–19” (e.g. 235/45R18 · 235/40R19) | follow vehicle license plate (typically ~ 2.5–2.7 bar ) | possible +0.1–0.2 bar if at full load | Check more often with 19” rims. |
*The measurements are common examples: always check the owner's manual and the pressure plate. Do not exceed the manufacturer's limits.
🛠️ Alignment, alignment and TPMS
- 3D convergence at every change of season or after impacts/curbs: prevents serrations and drifting.
- Camber : It's more sensitive on EVs. If the inner edges wear quickly, check the values and silent blocks.
- TPMS : After rotations/resets, drive for 10–20 min to stabilize readings.
- Shock absorbers : a tired setup creates “saw teeth.” Test at 60–80,000 km (sooner if the car is heavy/large wheels).

❓ Frequently Asked Questions
How often should I rotate the tires on my BYD?
Every 8–12,000 km (or 6–8 months). Change it sooner if you see a difference > 1.5 mm between axles or if the car pulls to one side.
What is the correct pressure for Dolphin/Seal?
Always refer to the BYD pressure plate on the door jamb. In real-world use, the pressure typically remains around 2.4–2.7 bar cold, depending on size and load. Do not exceed the manufacturer's specifications.
EVs wear out their brakes less: do we need to do something about the tires?
Yes: regeneration reduces brake use but increases tire work during deceleration. Regular rotations and correct pressures are essential.
Can I fit non-EV-ready tires?
Possible, but for EVs it's better to have a dedicated specification : better range, noise reduction and durability. On large wheels (18–19”) it's highly recommended.
🏁 Conclusions
On BYD Dolphin and BYD Seal, the winning strategy is: correct pressures (check monthly and before trips), timely rotations , 3D alignment when needed, and the choice of EV-ready tires . This reduces irregular wear, noise, and energy consumption, maximizing safety and range.
