Can I change the size of tyre that is fitted to my vehicle?

Whilst it is possible to change the size of tyre that is fitted to your vehicle, you should take great care in how you make any changes as it can have a negative impact on your vehicle:

1. Smaller diameter outside due to smaller tyre or rim size.

- Load capability issues 

- Issues to gear settings or the speedometer.

- Higher levels of fuel consumption

2. Bigger diameter outside due to bigger tyre or rim size.

- Impacting the wheel arch when steering 

- Heavier steering.

- Issues to gear settings or the speedometer.

The industry recommends that you if you do change size it is no greater than 1% difference ot the original tyre size.
