The Importance of Proper Tyre Inflation
Perhaps the single most important aspect of tyre care is maintaining proper inflation pressure. Tyres that are either under-inflated or over-inflated can lead to a host of problems:
Under-inflated Tyres:
– Excessive heat buildup leading to potential blowouts
– Increased rolling resistance causing reduced fuel economy
– Uneven wear on the outer edges of the tread
– Compromised handling and longer braking distances
– Increased risk of hydroplaning in wet conditions
Over-inflated Tyres:
– Reduced contact patch with the road
– Harsher ride quality
– Uneven wear concentrated in the center of the tread
– Increased vulnerability to impact damage from potholes and road hazards
– Decreased traction, especially on wet surfaces
Finding Your Vehicle’s Recommended Pressure
The recommended tyre pressure for your vehicle is not the maximum pressure listed on the tyre sidewall. Instead, look for:
1. A sticker inside the driver’s door jamb
2. Information in your owner’s manual
3. Details inside the fuel filler door on some vehicles
These sources will provide the manufacturer’s recommended pressures, which typically range between 30-35 PSI (pounds per square inch) for most passenger vehicles. Some vehicles specify different pressures for front and rear tyres.
How to Check Tyre Pressure Correctly
For the most accurate reading:
– Check pressure when tyres are “cold” (before driving or at least three hours after driving)
– Remove the valve cap and press the tyre gauge firmly onto the valve stem
– Read the pressure and compare to the recommended value
– Add air if needed, or release pressure by pressing the center pin in the valve stem
– Replace the valve cap to prevent dirt and moisture from entering
We recommend checking your tyre pressure at least once a month and before any long trips. At Paul Flood Automotive, we check and adjust tyre pressure during every service visit.
Understanding Tyre Wear Patterns
Tyre tread wear patterns can tell you a lot about your vehicle’s condition and your driving habits. Learning to “read” these patterns can help you address issues before they lead to premature tyre replacement.
Center Wear
Cause: Over-inflation
Solution: Adjust to proper inflation pressure
Edge Wear
Cause: Under-inflation
Solution: Maintain proper inflation pressure and rotate tyres regularly
One-sided Wear
Cause: Alignment issues or worn suspension components
Solution: Have alignment checked and corrected; inspect suspension components
Cupping or Scalloping
Cause: Worn shock absorbers, unbalanced tyres, or loose suspension components
Solution: Replace worn components and have tyres balanced
Feathering (smooth on one side, sharp on the other)
Cause: Alignment issues, particularly toe-in or toe-out problems
Solution: Have alignment checked and adjusted
At Paul Flood Automotive, our technicians are trained to identify these wear patterns and recommend the appropriate corrective actions to extend your tyre life.
The Importance of Regular Rotation
Tyres wear differently depending on their position on the vehicle. Front tyres typically experience more wear on front-wheel-drive vehicles, while rear tyres may wear differently on rear-wheel-drive vehicles. Regular rotation helps ensure even wear across all four tyres, maximising their lifespan.
Recommended Rotation Patterns
The optimal rotation pattern depends on your vehicle and tyre type:
For vehicles with same-sized, non-directional tyres:
– Forward Cross: Front tyres move to opposite sides of the rear; rear tyres move straight forward
– X-Pattern: Each tyre moves to the opposite corner of the vehicle
– Straight Rotation: Front tyres move straight back; rear tyres move straight forward
For vehicles with directional tyres:
– Front to back on the same side (maintaining direction of rotation)
For vehicles with different-sized front and rear tyres:
– Side-to-side rotation only
Rotation Schedule
We recommend rotating your tyres every 8,000-10,000 kilometers or according to your vehicle manufacturer’s specifications. At Paul Flood Automotive, we can incorporate tyre rotation into your regular service schedule for convenience.
Wheel Alignment and Balancing
Proper wheel alignment and balancing are critical for even tyre wear and optimal vehicle handling.
Wheel Alignment
Alignment refers to the adjustment of the angles of your wheels relative to each other and to the car body. Proper alignment ensures that your tyres meet the road at the correct angle, that your wheels are parallel to each other, and that your tyres are centered in the wheel wells.
Signs that your vehicle may need an alignment include:
– Vehicle pulling to one side
– Uneven or rapid tyre wear
– Crooked steering wheel when driving straight
– Squealing tyres
At Paul Flood Automotive, we recommend checking your alignment annually or after:
– Hitting a significant pothole or curb
– Being involved in an accident
– Installing new tyres
– Replacing suspension components
Wheel Balancing
Balancing ensures that weight is distributed evenly around the wheel and tyre assembly. Even small imbalances can lead to vibration, uneven wear, and stress on your vehicle’s suspension.
Signs your wheels may need balancing include:
– Vibration in the steering wheel, seat, or floorboard
– Vibration that increases with speed
– Scalloped or cupped wear pattern on tyres
We recommend having your wheels balanced when:
– Installing new tyres
– Rotating tyres
– You notice vibration
– A tyre has been repaired
– At least once a year as preventative maintenance
Seasonal Tyre Considerations for the Sutherland Shire
The Sutherland Shire’s climate presents specific challenges for tyre maintenance throughout the year.
Summer Considerations
– Higher temperatures can increase tyre pressure – check more frequently during hot spells
– Hot road surfaces can accelerate tyre wear – avoid aggressive driving on hot days
– Beach sand can get trapped in tread – rinse tyres after beach visits to prevent premature wear
Winter Considerations
– Cooler temperatures can decrease tyre pressure – check pressure more often in winter mornings
– Wet roads require good tread depth for water displacement – ensure at least 3mm of tread during rainy season
– Coastal salt exposure can damage wheels – wash regularly during winter months
Tyre Inspection Checklist
Regular visual inspections can help you catch potential issues before they become serious problems. We recommend checking your tyres at least monthly using this checklist:
1. Tread Depth: Insert a 20-cent coin into the tread groove with the platypus facing down. If you can see the platypus’s bill, your tread is too worn and the tyre needs replacement.
2. Sidewall Condition: Look for cuts, cracks, bulges, or objects embedded in the tyre sidewall.
3. Foreign Objects: Check for nails, screws, glass, or other objects embedded in the tread.
4. Uneven Wear: Look for wear patterns that might indicate alignment or inflation issues.
5. Valve Stems: Ensure they’re not cracked or damaged and that caps are in place.
6. Manufacturing Date: Tyres have a four-digit code indicating the week and year of manufacture (e.g., “1220” means the 12th week of 2020). Tyres generally should be replaced after 5-6 years, regardless of tread depth.
When to Replace Your Tyres
Even with perfect maintenance, all tyres eventually need replacement. Here are the key indicators that it’s time for new tyres:
– Tread worn to the wear indicators (bars that appear across the tread when worn to 1.6mm)
– Visible damage such as cuts, cracks, bulges, or punctures that cannot be safely repaired
– Age exceeding 5-6 years, regardless of tread depth
– Persistent vibration or noise that cannot be resolved with balancing
– Flat spots from extended parking or emergency braking
