What is Wheel Alignment?
Wheel alignment refers to the adjustment of your vehicle’s suspension system—the connection between your vehicle and its wheels. It’s not an adjustment of the tires or wheels themselves, but rather the angles at which they make contact with the road.
The Three Key Alignment Angles
Proper wheel alignment involves adjusting three primary angles:
1. Camber: The inward or outward tilt of the tire when viewed from the front. Proper camber ensures even tire wear across the tread.
– Positive camber: Top of tire tilts outward
– Negative camber: Top of tire tilts inward
– Ideal: Slight negative camber for better cornering stability
2. Toe: The direction your tires point relative to the centerline of the vehicle when viewed from above.
– Toe-in: Front of tires point toward each other
– Toe-out: Front of tires point away from each other
– Ideal: Slight toe-in for most vehicles to promote straight-line stability
3. Caster: The angle of your steering axis when viewed from the side, affecting steering stability and cornering.
– Positive caster: Steering axis tilts toward the driver
– Negative caster: Steering axis tilts toward the front of the vehicle
– Ideal: Positive caster for better straight-line tracking and stability
The Alignment Process
At Paul Flood Automotive, our wheel alignment process includes:
1. Initial inspection: Checking tire condition, suspension components, and steering parts
2. Mounting alignment equipment: Attaching precision sensors to each wheel
3. Measurement: Comparing current alignment angles to manufacturer specifications
4. Adjustment: Carefully altering suspension components to achieve proper alignment
5. Road test: Verifying that the vehicle drives straight and handles properly
What is Wheel Balancing?
While alignment focuses on the angles of the wheels, balancing addresses weight distribution around each wheel and tire assembly.
Why Wheels Need Balancing
Even seemingly perfect wheels and tires can have slight weight imbalances:
– Manufacturing variations in tires and wheels
– Uneven wear patterns over time
– Weight distribution changes from tire repairs
– Loss of wheel weights due to road impacts
These imbalances, sometimes as small as a few grams, can cause noticeable vibrations at certain speeds.
The Balancing Process
Our wheel balancing procedure includes:
1. Mounting: Securing the wheel/tire assembly on a specialised balancing machine
2. Spin test: Rotating the assembly at high speed to measure imbalances
3. Measurement: Identifying the exact locations and amounts of imbalance
4. Correction: Adding precisely calculated weights to specific locations on the wheel
5. Verification: Re-testing to confirm proper balance has been achieved
Signs Your Vehicle Needs Alignment or Balancing
Alignment Warning Signs
1. Uneven or rapid tire wear: Particularly along the edges of the tread
2. Vehicle pulling to one side: Requiring you to hold the steering wheel off-center
3. Crooked steering wheel: When driving straight, your steering wheel isn’t centered
4. Squealing tires: Especially when taking corners
5. Feeling of looseness or wandering: Vehicle seems to drift or wander on straight roads
Balancing Warning Signs
1. Vibration in the steering wheel: Typically felt at specific speeds (often 50-70 km/h)
2. Vibration in the seat or floorboard: Usually indicates rear wheel imbalance
3. Vibration that increases with speed: Gets worse as you drive faster
4. Scalloped or cupped wear pattern: Tire tread shows uneven wear in a wave-like pattern
5. Excessive wear on suspension components: Imbalanced wheels put extra stress on bearings and bushings
The Benefits of Regular Alignment and Balancing
Extended Tire Life
Properly aligned and balanced wheels can significantly extend your tire life:
– Even tread wear across all tires
– Prevention of premature wear patterns
– Maximised use of the entire tread surface
– Potential for up to 20% longer tire life
For a set of quality tires costing $800-1,200, this represents significant savings over time.
Improved Fuel Efficiency
Misaligned wheels create drag and resistance:
– Tires that aren’t properly aligned create more rolling resistance
– This resistance requires more engine power to overcome
– The result is increased fuel consumption
– Proper alignment can improve fuel economy by 7-10%
For the average driver, this can translate to savings of $100-200 per year in fuel costs.
Enhanced Safety
Perhaps most importantly, proper alignment and balancing improve vehicle safety:
– Better handling in emergency situations
– More predictable steering response
– Reduced risk of hydroplaning
– Improved braking performance
– Less driver fatigue from fighting the steering wheel
Improved Comfort and Reduced Fatigue
A properly aligned and balanced vehicle provides:
– Smoother ride quality
– Reduced vibration
– Less steering wheel fight on long drives
– More predictable handling
– Quieter operation
Protection of Other Vehicle Components
Alignment and balancing protect more than just your tires:
– Reduced stress on suspension components
– Less wear on steering linkages
– Extended life of wheel bearings
– Protection of expensive electronic stability control systems
– Prevention of premature shock absorber wear
What Causes Alignment and Balance Issues?
Common Causes of Misalignment
1. Impact with road hazards:
– Hitting potholes
– Running over curbs
– Striking road debris
– Speed bumps taken at excessive speed
2. Normal wear and settling:
– Suspension component wear
– Spring sagging over time
– Bushing deterioration
– Gradual shifting of components
3. Vehicle modifications:
– Lowering or lifting the vehicle
– Changing to non-standard tire sizes
– Installing aftermarket suspension components
– Adding heavy accessories that alter weight distribution
4. Accident damage:
– Even minor collisions can affect alignment
– Frame or subframe shifts
– Bent components that may not be visibly obvious
Common Causes of Wheel Imbalance
1. Normal wear:
– Tires wear unevenly over time
– Tread rubber loss changes weight distribution
– Internal tire structure changes with age and use
2. Lost wheel weights:
– Adhesive weights can fall off
– Clip-on weights can be knocked off by curbs or road debris
– Corrosion can cause weight loss or shifting
3. Rim damage:
– Bent rims from potholes or curbs
– Corrosion that changes weight distribution
– Accumulated mud or debris inside the wheel
4. Tire repairs or replacements:
– Patches or plugs add weight to specific areas
– New tires require fresh balancing
– Tire rotation without rebalancing
How Often Should You Get Alignment and Balancing?
Wheel Alignment Recommendations
For typical driving in the Sutherland Shire, we recommend:
– Every 2 years or 30,000 kilometers for normal driving conditions
– Annually if you frequently drive on rough roads or hit potholes
– After any significant impact with potholes, curbs, or road debris
– When installing new tires
– When replacing suspension or steering components
– If you notice any alignment symptoms mentioned earlier
Wheel Balancing Recommendations
For optimal performance and tire life:
– Every 10,000-12,000 kilometers as part of regular rotation service
– When installing new tires
– After any tire repair (patches, plugs)
– If you notice vibration at specific speeds
– When rotating tires from one position to another
Special Considerations for Different Vehicles

– More precise alignment specifications
– Consideration of performance-oriented alignment settings
– Greater sensitivity to minor alignment issues
SUVs and 4WDs
– More susceptible to alignment changes due to higher center of gravity
– May require special attention to load-carrying alignment
– Often benefit from slightly different specifications when used off-road
– More prone to balance issues with larger, heavier wheels and tires
Older Vehicles
– May have worn components that make perfect alignment impossible
– Often require component replacement before alignment
– May need more frequent checks due to worn suspension
– Sometimes benefit from aftermarket parts to restore proper geometry
DIY vs. Professional Service
Can You Check Alignment Yourself?
While professional equipment is needed for precise measurements, you can look for these warning signs:
1. Visual tire inspection:
– Uneven wear patterns
– More wear on inside or outside edges
– Feathering or scalloping of the tread
2. Simple driving tests:
– On a safe, straight, level road with no traffic, briefly release the steering wheel to see if the vehicle pulls to one side
– Check if your steering wheel is centered when driving straight
– Listen for unusual tire noise on smooth roads
3. Steering wheel position:
– When driving straight, your steering wheel should be level
– If it’s off-center, alignment is likely needed
Why Professional Service Matters
While DIY checks can identify problems, professional service is essential because:
1. Precision equipment: Modern alignment requires computerised equipment accurate to fractions of a degree
2. Manufacturer specifications: Professionals have access to exact specifications for your specific vehicle
3. Comprehensive inspection: Technicians can identify worn components that would make alignment ineffective
4. Expertise in adjustment: Many modern vehicles have complex adjustment procedures
5. Verification: Professional service includes road testing to confirm results

Frequently Asked Questions
Q: Will I immediately notice a difference after alignment and balancing?
A: Most drivers notice immediate improvements in handling, steering feel, and ride comfort. Vibrations from imbalance should disappear completely. However, some benefits, like improved tire wear and fuel economy, develop over time.
Q: My vehicle has low profile tires. Does this affect alignment needs?
A: Yes. Vehicles with low profile tires are more sensitive to alignment issues and often show symptoms more quickly. They typically benefit from more frequent alignment checks and may require more precise adjustments.
Q: I recently had new tires installed. Do I need alignment?
A: While not absolutely required, alignment with new tires is highly recommended. New tires represent a significant investment, and proper alignment helps ensure they wear evenly from the start, maximising your return on that investment.
Q: My vehicle was aligned recently, but it still pulls to one side. What could be wrong?
A: Several issues could cause this:
– Tire pressure differences
– Tire conicity (internal manufacturing characteristic)
– Brake system problems
– Road crown compensation
– Damaged or worn suspension components
– Shifted body or frame components
A thorough inspection by our technicians can identify the specific cause.
Q: Does wheel balancing fix cupped or scalloped tire wear?
A: While balancing can prevent this type of wear from developing, once the wear pattern is established, balancing alone won’t fix it. The tires will likely continue to make noise and cause vibration until replaced. However, balancing new tires properly will prevent the issue from recurring.
