Tyres.co.uk offers alternatives for Volkswagen Golf GTI Mk8 with 18-inch Richmond wheels and 225/40 R18 92Y XL for Michelin Pilot Sport 5 and Goodyear Eagle F1 Asymmetric 6. Make sure to check the registration and tyre-pressure label as there are different Volkswagen Golf GTI wheel options.
To find the exact size of the tyre, look on the sidewall of the tyres and on the tyre pressure label. (On newer models, the label is inside the door frame on the passenger side door.) If the label is missing, look inside the fuel filler door on earlier Golf GTIs, as the label may be there. For both, check the label along with the registration and check which are the approved fitments.
All Volkswagen Golf GTI models, including the GTI Clubsport and GTI Edition 50 models, are front wheel drive models, therefore, no Golf GTI features an all wheel drive system which would require all four tyres to match. When purchasing new tyres, ensure that they are a set and replace tyres on the same axle. When replacing two tyres, place them on the rear axle.
