How to check your tyre size & find the right fit for your car
Tyres come in many different sizes to suit different vehicle models, so when the time comes to purchase new tyres, it is important to understand that one size does not fit all. Whether you want to learn how to determine which size tyres you need, where to find your tyre size, or if you're looking for more information regarding what tyre size numbers mean, you're in the right place.
What size are my tyres?
There are four reliable ways to find what size your tyres are:
Read it off the tyre sidewall (easiest). Look for a sequence like 205 / 50 / R16 91 V moulded into the rubber. Every type on the car carries it, so you can check any wheel.
Check the driver’s door jam. Open the driver’s door and look at the placard on the frame or door edge, manufacturers list the recommended size and pressures there.
Look in your vehicle handbook. The recommended sizes are listed under wheels and tyres.
Check by your registration number. Enter your number plate to see the sizes and tyres that fit your car - the quickest option if you’re not with your vehicle. Check your tyre size by registration here.
Tip: If the sizes on different wheels do not match, look into it before you buy - see do your tyres need to match here.

Can you change your tyre size?
Your car tyres have been selected due to their ability to fit correctly on your vehicle's rims. The combination of your rims and your tyres have also been balanced to aid optimal suspension and steering, thereby offering a safe and comfortable driving experience.
If you were to change the tyre size of your vehicle's rims, it would theoretically be possible to change your tyre size, however, the wheel's overall diameter would need to remain the same. If you did decide to change the diameter, there are other considerations that you would also need to make, including recalibrating your speedometer and adjusting your tyre pressure.

It is important to never drive on mismatched tyres. Different tyres are designed with different tread patterns, which channel debris and water away from the surface of the tyre. This process allows the tyre to maintain a grip on the road surface, which is essential to safety, handling and performance. If you drive on mismatched tyres that channel debris and water in different directions, the handling of your vehicle on loose road surfaces or in wet conditions will be negatively impacted. Additionally, your vehicle's suspension will be put under unnecessary stress, which can cause premature and/or uneven wear.
