Tyre Maintenance Essentials
Proper car tyre maintenance is crucial for safety, performance, and longevity. Implementing these maintenance practices can extend tyre life and enhance driving safety:
Regular Inspection
Visually inspect tyres weekly for signs of wear, damage, and irregularities. Look for punctures, cuts, cracks, blisters, or foreign objects embedded in the tread. Uneven wear can indicate alignment, suspension, or under-inflation issues that need addressing.
Frequency: Weekly and before long trips
Tyre Rotation
Rotating car tyres ensures even wear and extends their life. Front tyres typically wear faster on FWD vehicles due to steering and weight differences during braking. Rotating the tyres in a criss-cross or rearward-external pattern redistributes wear and maintains optimal traction.
Frequency: Every 5,000 to 8,000 km
Proper Inflation
Maintaining the correct tyre pressure is critical for safety, fuel efficiency, and performance. Under-inflation causes more heat build-up, increasing the risk of blowouts, while over-inflation results in uneven wear and a harsh ride. Check tyre pressure with a gauge at least once a month.
Frequency: Monthly and before long trips
Alignment and Balancing
Proper wheel alignment ensures even wear and optimal handling. Misalignment causes tyres to wear unevenly and affects vehicle control, leading to safety risks. Balancing the car's tyres reduces vibrations, improves ride comfort, and increases suspension and steering component life.
Frequency: Every 20,000 km or when uneven wear is noticed
Money-Saving Tip: Regular tyre maintenance can extend tyre life by up to 30% and improve fuel efficiency by 3-5%, saving hundreds of dollars annually.
How to Choose the Right Car Tyres

Local climate significantly impacts tyre selection. Regions with severe winters require dedicated winter tyres, while milder climates may be well-served by all-season options. Areas with frequent rain need tyres with excellent wet traction capabilities.
Tyre Size & Specifications
Always match the manufacturer's recommended tyre size and load capacity. This information can be found in your vehicle's owner's manual or on the driver's door jamb. Deviating from these specifications can affect handling and safety.
Performance Requirements
High-performance vehicles require tyres that can handle their capabilities. Ensure the speed rating matches or exceeds your vehicle's top speed, and consider handling characteristics for your driving style.
Quality & Brand Reputation
Established tyre manufacturers generally offer more reliable products with consistent performance. Research brands with good reputations for quality, durability, and customer satisfaction.
Cost vs. Value
While premium tyres cost more upfront, they often provide better value through longer tread life, improved performance, and enhanced safety features. Calculate the cost per mile rather than just the purchase price.
Important: Never compromise on tyre quality to save money. Tyres are your vehicle's only contact with the road and are critical safety components. Investing in quality tyres can prevent accidents and save lives.
DIY Tyre Replacement Guide
While professional tyre installation is recommended, knowing how to change a tyre is an essential skill for handling roadside emergencies. Follow these steps for a safe tyre change:
-
Prepare for Safety
Find a flat, stable surface away from traffic. Turn on hazard lights, apply the parking brake, and place wheel chocks on the wheels diagonally opposite the flat tyre.
-
Gather Equipment
Locate your spare tyre, jack, jack handle, and wheel wrench. Refer to your vehicle's owner's manual for specific jacking points and procedures.
-
Loosen Wheel Nuts
Before lifting the car, use the wheel wrench to loosen (but not remove) the wheel nuts by turning counterclockwise. If the nuts are too tight, you may need to apply more force or use a breaker bar.
-
Position and Raise the Jack
Place the jack under the designated jacking point nearest to the flat tyre. Raise the vehicle until the tyre is about 15 cm off the ground.
-
Remove and Replace the Tyre
Remove the wheel nuts completely and take off the flat tyre. Mount the spare tyre onto the wheel hub, aligning the holes. Hand-tighten the wheel nuts in a star pattern.
-
Lower the Vehicle and Finalize
Lower the vehicle so the tyre touches the ground but doesn't bear full weight. Tighten the wheel nuts with the wrench in a criss-cross pattern. Lower the vehicle completely and remove the jack.
Essential Tyre Changing Tools
Jack
Used to lift the car off the ground. Always use on a flat, stable surface at the manufacturer's recommended jacking points.
Jack Handle
Used to operate the jack mechanism, allowing you to raise and lower the vehicle safely.
Wheel Wrench
A specialized tool for removing and tightening wheel nuts. Some have extendable handles for additional leverage.
Wheel Chocks
Wedges placed against wheels to prevent the vehicle from rolling during the tyre change process.
Safety Warning: Never get under a vehicle supported only by a jack. If you need to work underneath the vehicle, use proper jack stands. Also, have your temporary spare tyre replaced with a regular tyre as soon as possible, as they're not designed for extended use or high speeds.
Frequently Asked Questions
There are several reliable methods to determine if a tyre is worn out:
- Visual inspection: Look for cracks, bulges, or blisters on the sidewall or tread surface, which indicate structural weakness.
- Tread depth measurement: Use a tread depth gauge to measure the remaining tread. In most countries, the legal minimum is 1.6mm.
- Tread wear indicators: Most modern tyres have built-in wear bars that become visible when the tread reaches minimum depth.
- The penny test: Place a penny in the tread groove with the queen's head upside down - if you can see the top of the head, the tread is too worn.
- Uneven wear patterns: These can indicate alignment or inflation issues and may require tyre replacement.
Proper tyre maintenance is critical for multiple reasons:
- Safety: Well-maintained tyres provide better traction, shorter stopping distances, and reduced risk of blowouts or hydroplaning.
- Performance: Properly maintained tyres improve handling, cornering ability, and overall vehicle control.
- Fuel efficiency: Correctly inflated and aligned tyres can improve fuel economy by 3-5%.
- Cost savings: Regular maintenance extends tyre life, postponing the expense of replacement.
- Environmental impact: Proper tyre care reduces waste and improves fuel efficiency, lowering emissions.
While it's possible to replace only two tyres, there are important considerations:
- If replacing only two tyres, always install them on the rear axle, regardless of which wheels are driven.
- The new tyres should be the same size, type, and preferably brand as the existing ones.
- The remaining two tyres should have adequate tread depth (at least 4-5mm) and be in good condition.
- Mixing tyre types (e.g., all-season with summer) can create handling imbalances and compromise safety.
- For all-wheel drive vehicles, manufacturers often recommend replacing all four tyres simultaneously to prevent drivetrain damage.
For optimal safety and performance, replacing all four tyres at once is generally recommended when significant wear is present.
The correct tyre size is critical for vehicle safety and performance:
- Always follow the vehicle manufacturer's recommended tyre size, found in the owner's manual or on the driver's door jamb sticker.
- The tyre size code (e.g., 205/55R16) indicates width (205mm), aspect ratio (55% of width), construction type (R for radial), and rim diameter (16 inches).
- Ensure any replacement tyres have the same or higher load index and speed rating as the original equipment.
- While alternative sizes may be technically compatible, they can affect speedometer accuracy, ground clearance, and handling characteristics.
- Consult with a tyre professional if you're considering a different size for performance or aesthetic reasons.
