Recommended Tyre Pressure for Motorway Driving

For long-distance or high-speed motorway driving:

• Increase rear tyres by +2 psi (0.1 bar)
• Ensure tyres are checked cold, not after driving
• Avoid under-inflation, as it raises heat buildup and fuel usage

How Tyre Pressure Affects the C3 Aircross Handling

Under-inflated Tyres

• Sluggish steering
• Increased fuel consumption
• Higher heat and wear on sidewalls
• Risk of blowouts

Over-inflated Tyres

• Reduced grip
• Harsher ride
• Uneven central tread wear

Step-by-Step: How to Check Tyre Pressure on the Citroën C3 Aircross

1. Find a cold-tyre reading

Pressures must be checked when tyres are cool (parked 3+ hours).

2. Use a digital pressure gauge or portable compressor

Accuracy is key—avoid unreliable petrol station gauges.

3. Remove valve caps

Keep them safe; they protect against debris.

4. Read and compare values

Match the reading to the recommended PSI/BAR.

5. Inflate or deflate as needed

Use a compressor to adjust precisely.

6. Re-check after driving short distances

Pressure stabilizes after short trips.

When to Replace Tyres on the Citroën C3 Aircross

Replace tyres when:

• Tread depth is below 3 mm (legal minimum is 1.6 mm)
• Cracks or bulges appear
• Age exceeds 6 years
• Steering becomes less precise despite correct pressure

Tyre Pressure Tips for Better Fuel Efficiency

To optimise consumption:

• Keep tyres consistently at front 32–35 psi depending on version
• Avoid carrying unnecessary weight
• Check pressures every two weeks
• Use nitrogen inflation for more stable pressure retention (optional)

Seasonal Tyre Pressure Adjustments

Winter

Cold weather reduces pressure by ~1 psi every 5°C.
→ Increase by +2 psi in colder climates.

Summer

Heat expands air.
→ Never exceed recommended max PSI.
