Why Tyre Size Matters
Tyre size isn’t just a number—it’s a critical specification that impacts your vehicle’s:
Road grip and braking distance
Ride comfort and cabin noise
Fuel efficiency
Suspension performance
Tyre lifespan and tread wear
Safety, especially in wet or high-speed conditions
The wrong tyre size can lead to poor handling and accelerated wear. That’s why choosing a trusted, expert tyre provider is vital when it’s time to change your tyres.
Your Trusted Partner for All Tyre Sizes
At Tyre Doctors, we understand that customers need more than just tyres—precision, reliability, and peace of mind. That’s why we stock and fit tyres in a wide range of sizes for all vehicle types, including:
Hatchbacks and sedans
SUVs and 4WDs
Performance and sports cars
Light commercial vehicles
European luxury vehicles (BMW, Audi, Mercedes-Benz, Porsche, and more)
With our world-class tyre changers and wheel balancers from Hunter Engineering, we ensure every tyre is fitted and balanced to the highest global standards.
How to Find the Right Tyre Size
If you’re not sure about your current tyre size, it’s easy to check. You’ll find the size embossed on the sidewall of your tyre in a format like this:
Example: 225/45R17
Here’s what it means:
225 – Tyre width in millimetres
45 – Aspect ratio (height as a % of width)
R – Radial construction
17 – Diameter of the wheel in inches
If you prefer expert help, just bring your vehicle to Tyre Doctors and we’ll do it for you. Every customer receives a free, no-obligation tyre check and detailed report, so you’ll know exactly what your vehicle needs—no guesswork, no pressure.
Tailored Service for Every Tyre Size
We carry everything from 13-inch compact car tyres to 22-inch performance SUV tyres. We also supply low-profile, run-flat, off-road, and performance tyres in a wide range of dimensions.
If your vehicle requires a specialty size that’s difficult to find elsewhere, our team can source and fit it quickly. We work with leading global brands such as Bridgestone, Michelin, Goodyear, Pirelli, and Continental.
Need Help Finding the Right Fit?
Not all vehicles use the exact tyre sizes, even within the same model range. If you’ve changed your wheels, or your vehicle is imported or modified, you may need assistance identifying the ideal tyre size.
At Tyre Doctors, we take the guesswork out of tyre sizing:
We check your car’s compliance plate or manual
We assess current wear patterns and alignment
We verify rim compatibility
We advise on upsizing or downsizing safely
