There are many questions that may arise when you have to replace one or multiple wheels. Tyre fitting can be difficult when there are so many different tyres and tyre brands to choose from. Continental has various recommendations to help you avoid tyre damage and uneven tyre wear, and to help you get the best value.
It is recommended that you replace all ground-contact vehicle tyres at the same time. If this is not possible, then at least replace all on the same axle – so either all on the front axle or all on the rear one. For a better driving and car-handling experience, avoid mixing – i.e., avoid replacing only one of the front tyres and one of the rear tyres.
If only one axle-set of tyres is replaced, then it is generally recommended that you fit the most recently acquired tyres together on the rear axle, rather than mixing old and new between the rear and front axle. This may complicate tyre rotation, and caution is urged if the tyres have significant differences, such as state of wear on the tread, tyre size, construction and speed ratings, which may already affect vehicle wheel balance. Consult a trained specialist for best practices.
Placing greater grip on the rear axle is generally recommended to prevent possible over-steering and loss of vehicle stability on wet or icy surfaces. Some car manufacturers recommend fitting the newest tyres with better tread on wheels on the front axle. Consult with the car manufacturer, tyre specialist and/or a fitting service for further information on tyre replacement and fitting.
