BYD Shark 6 Tyre Pressure Guide: Correct PSI for All Conditions

The BYD Shark 6's recommended cold tyre pressures are 250 kPa (2.5 bar / 36 PSI) front and rear when unloaded, and 250 kPa front / 290 kPa (2.9 bar / 42 PSI) rear when fully loaded. When towing, increase rear pressure by at least 20 kPa above normal. These figures apply to the standard 265/65 R18 tyres. Always measure when cold (at least 3 hours after driving or within 1.6 km of movement).

Why Tyre Pressure Matters More on the Shark 6?

The Shark 6 weighs 2,710 kg at kerb weight, making it one of the heaviest vehicles in the Australian ute segment. It also tows up to 2,500 kg braked and carries payloads in the tray. Combined with a PHEV powertrain where every kWh of electric range counts, correct tyre inflation directly affects range, towing stability, and tread life.

The owner's manual warns: driving with underinflated tyres causes uneven wear, affects handling, and increases power consumption. On a ute that transitions between unladen commuting and loaded weekend trips, checking pressure before each condition change is essential.

Front vs Rear: Unloaded vs Fully Loaded

Unlike most passenger cars with a fixed split, the Shark 6 uses equal pressure front and rear when empty (250/250 kPa) and higher rear pressure when loaded (250/290 kPa). This is because an empty ute tray puts minimal load on the rear axle, while a loaded tray or passengers shift weight dramatically rearward.

• Empty commuting: 250 kPa all round provides comfortable, balanced handling
• Loaded tray or 5 passengers: Increase rear to 290 kPa to compensate for added weight
• Towing: Increase both axles, rear must be at least 20 kPa above the normal recommendation

Forgetting to adjust rear pressure when loading up is the most common tyre mistake Shark 6 owners make.

Hot vs Cold Inflation

Always measure when cold (3+ hours after stopping or within 1.6 km). The manual states: "It is normal that tire pressure readings measured when tires are hot are 0.3-0.4 bar higher than those when tires are cold. Do not deflate tires to achieve the specified cold tire pressure reading."

How TPMS Works on the Shark 6?

The Shark 6 has a comprehensive Tyre Pressure Monitoring System with three alert levels:

• Low pressure alarm: Triggers when any tyre drops below 75% of standard pressure. The warning light illuminates and the pressure value turns yellow on the instrument cluster.
• High temperature alarm: Activates when any tyre exceeds 85°C for three consecutive minutes. The temperature value turns yellow. Stop and wait for the tyre to cool before driving.
• System fault: Warning light flashes then stays solid. "No Signal" or "Please check TPMS" displays. Check the monitoring module and surrounding electromagnetic interference.

The TPMS monitoring module transmits data periodically, not continuously. If a tyre deflates suddenly between transmissions, the system may not alert immediately. Always check visually before driving. If your TPMS warning light appears alongside other dashboard symbols, see our Shark 6 dashboard warning lights guide for what each symbol means.

Effect of Wrong Pressure on Range and Fuel Economy

• 10% underinflated: ~3-5% increase in energy consumption (both electric and petrol modes)
• 20% underinflated: ~6-10% increase, plus accelerated shoulder wear
• EV range impact: 81-92 km electric range can lose 5-9 km from 20% underinflation alone

Adjusting Pressure When Towing

Towing adds significant load to the rear axle. The owner's manual provides specific towing pressure guidance:

• Rear tyre pressure when towing: Must be at least 20 kPa above the pressure recommended for normal driving conditions
• For towing at full capacity: Front 270 kPa, rear 310 kPa (recommended based on manual guidelines)
• Maximum towing speed: Do not exceed 100 km/h under any circumstances
• Rear axle overload limit: Technically permissible maximum rear axle mass may be exceeded by no more than 15% when towing. Vehicle speed must not exceed 100 km/h in this case.

After disconnecting the trailer, remember to reduce rear pressure back to the unloaded specification (250 kPa). Driving unladen on towing pressures causes centre-tread wear. Keep your Shark 6's software current for the best TPMS accuracy. See our Shark 6 OTA updates guide.

When to Replace Tyres

• Tread below 1.6 mm: Legal minimum. Wear bars show when reached.
• Visible cracks, bulges, or cord: Replace immediately.
• Typical life: 40,000-60,000 km depending on loads and towing frequency.
• Lug nut torque: 140 Nm after any wheel replacement.

Common Mistakes Shark 6 Owners Make

• Running loaded-tray pressure when empty. 290 kPa rear on an empty ute causes harsh ride and centre wear. Drop to 250 kPa when unloaded.
• Deflating hot tyres to match cold specs. The manual explicitly warns against this. 30-40 kPa above cold readings is normal when hot.
• Forgetting to increase rear pressure for towing. The manual requires at least 20 kPa above normal. Towing on standard pressures risks rear tyre failure.
• Ignoring the 85°C temperature alarm. This is a serious warning. Stop and let the tyre cool completely before continuing.
• Never rechecking after season changes. Cold weather drops pressure approximately 7 kPa per 10°C. Check monthly through autumn and winter.
