2022-on UK manual index
Selected full-size wheel entries in the manufacturer manual linked by Hyundai UK. The manual index range identifies the source selection, not confirmation for every production year. Engine, package and equipment can limit fitment; verify the handbook and placard for the exact vehicle.
Check your exact vehicle. These are selected documented combinations, not a registration lookup or a complete fitment list. A tyre with the same size can have a different load index, speed rating, construction or manufacturer approval.
