Yes, entering your UK registration can return the original fitment for many cars, but imported Monaros or vehicles with modified wheels may need a manual tyre size search to confirm the correct fit.
Check the tyre sidewall for a code like 235/45 R18, or look in the handbook or door jamb sticker (where fitted). The numbers indicate width, profile, wheel diameter, plus load and speed ratings.
In the UK it is best practice to fit matching tyres on the same axle with the same size, construction type and similar tread depth to maintain stable handling and braking.
The legal minimum is 1.6mm across the central three-quarters of the tyre around the full circumference, but many drivers replace earlier (often around 3mm) for better wet grip.
After selecting tyres, you can choose a nearby fitting partner and appointment time, then pay online. The tyres are sent to the garage for your visit, with fitting details shown at checkout.
