Common Tyre Questions

A: When choosing the best tyres for your needs/vehicle, consider factors such as tyre size, driving conditions, and budget.

Search our range and request pricing for tyres you believe will be a best fit for you – Or alternatively, reach out to the team at one of our branches and they’ll suggest the best tyre for your needs.

A: Tyres should generally be replaced every 5-6 years or when the tread depth reaches the legal minimum tread depth 1.5mm. However, we recommend to change your tyres at 3mm or sometimes earlier depending on the terrain and season.

A: You should check your tyre pressure at least once a month and before long trips.

  • Driving with incorrect pressure can reduce fuel efficiency, affect handling and increase tyre wear.

Always follow the pressure recommended by your vehicle manufacturer.

A: Refer to your vehicle manual or tyre placard for the manufacturer’s recommended tyre pressure specifications.

Or pop into our branch and our team can check your tyre pressure specification for you.

A: Uneven tyre wear is usually caused by:

  • Incorrect tyre pressure
  • Wheel alignment issues
  • Unbalanced wheels
  • Worn suspension components

These issues can reduce tyre life and affect safety if not fixed.

A: Tyres should generally be rotated every 8 000 -12 000 km (or during regular servicing).

Rotation helps:

  • Even out wear
  • Improve handling
  • Extend the life of your tyres

A: Wheel balancing ensures the weight of the tyre and wheel is evenly distributed.

It helps to reduce vibration, improve ride comfort, prevent uneven wear. If your tyres are out of balance, you may feel shaking at certain speeds.

A: Look out for:

  • Low tread depth
  • Uneven wear
  • Cracks or bulges
  • Increased vibration or noise

Tyres are your only contact with the road, so worn tyres directly affect safety.

A: Try using a 20-cent coin, if part of the number is visible when inserted into the tread, your tyres may need replacing.

If you’re not sure, bring your vehicle in for a check at one of our Dunedin branches.

NZ’s legal minimum tread depth is 1.5mm.

A: The Tyrewise Stewardship Fee is a charge applied to the sale of tyres and covers the costs associated with the collection, recycling, and environmentally responsible disposal of used tyres.

For more information, including specific fees, you may want to check the official Tyrewise website.

A: The speed rating indicates the maximum safe speed a tyre can handle. It’s marked on the tyre sidewall and should match your vehicle’s requirements

A: This could be due to unbalanced wheels, wheel misalignment, or worn-out suspension components. A wheel alignment and balancing check can help find the cause.

A: Yes. Your tyres can have a significant impact on fuel consumption. Keeping your tyres properly maintained can help reduce fuel use while also improving safety and tyre life.

A: depending on where the puncture is and how severe the damage is, a puncture can be repaired.

When to repair a puncture:

  • The hole is small (typically caused by a nail or screw)
  • The damage is in the centre tread area
  • The tyre structure is still in good condition

A tyre will need replacing if:

  • The puncture is in the sidewall or edge of the tyre
  • The hole is large or the tyre is badly damaged
  • The tyre has been driven on while flat

Not all punctures are safe to repair, so it’s always best to have the tyre inspected to confirm the right option.

A: Run-flat tyres are designed to be capable of operating at lower speed and for a limited distance without air, in the case of a puncture. If a puncture occurs, run flat tyres allow you to keep driving for a limited amount of time. In normal operation Run-flat tyres still require inflation to the pressure shown on the vehicle tyre placard.

Not all vehicles can be fitted with Run-flat tyres. You can find out more about Bridgestone Run-Flat technology here.

Common Wheel Questions

A: Not all wheels fit all vehicles. Your wheels need to match:

  • Bolt pattern (stud pattern),
  • Offset
  • Wheel size (diameter and width)
  • Centre bore (every vehicle has a unique centre bore)

If these don’t match, the wheels may not fit correctly or safely.

A: A Wheel fitment refers to how a wheel fits onto your vehicle.

It ensures the wheel bolts on correctly, clears brakes and suspension, sits properly within the guards

Incorrect fitment can cause rubbing, vibration, and handling issues.

A: The bolt pattern describes how many studs your wheel has and how they are spaced.

For example, 5×114.3 means 5 studs in a 114.3mm circle.

If the bolt pattern is wrong, the wheel won’t fit your vehicle.

A: Offset is how far the wheel sits in or out from your vehicle.

  • Positive offset = wheel sits further in
  • Negative offset = wheel sticks out more

Getting this wrong can cause rubbing on suspension or guards, poor handling or extra stress on other components.

A: In many cases, yes,  but it depends on the vehicle.

Going too big can cause clearance and safety issues. Check with your local automotive centre to find out what wheels your vehicle can fit.

A: Yes, but they must meet safety requirements.

You may need certification if:

  • Wheels are not suitable for the vehicle
  • Tyres stick outside the guards
  • Modifications affect safety

If unsure, it’s best to check with a professional before fitting.

A: CBL rings (also called hub rings or centre bore rings) are used to help a wheel sit centred on your vehicle’s hub.

When aftermarket wheels have a larger centre bore than your vehicle, a CBL ring fills the gap so the wheel fits perfectly.

Without CBL rings, aftermarket wheels often may not sit correctly, which can lead to vibration even if the wheels are balanced.

A: “Mag wheels” is a now common term used for alloy wheels, but previously was used to describe wheels made specifically from Magnesium Alloy.

Most modern wheels are made from aluminium alloy, which are lighter than steel, often offer better performance and handling, and offer more styling options

A: In many cases, yes. Wheel repairs can include straightening bent wheels, fixing scratches and kerb damage, and repainting or refinishing

Severely or structurally damaged wheels may need to be replaced.

A: Yes, wheel balancing helps:

  • Reduce vibration
  • Improve ride comfort
  • Prevent uneven tyre wear

Unbalanced wheels can cause shaking, especially at higher speeds.

A: Signs to look for include:

  • Vibration while driving
  • Uneven tyre wear
  • Visible damage or bends
  • Ongoing tyre pressure loss

If you notice any of these, it’s best to get your wheels inspected.

A: Yes — our team can help with:

  • Wheel fitment advice
  • Choosing the right size and style
  • Checking compatibility with your vehicle
