On the safe side with steel rims
Steel rims with winter tyres present no safety risk, even without any additional treatment. On the contrary: the material is significantly more stable and thus less vulnerable to de-icing salt, grit etc. Steel rims do rust from time to time, but only on the surface and without affecting their stabilising properties. A sensible compromise is therefore to swap the rims with the tyres. In October, when it’s time to change over to winter tyres, it is best to switch from your alloy wheels to their steel equivalents.
Correct fitting of winter tyres on alloy or steel rims
Regardless of sporty aluminium or robust steel rims – ultimately the decision is down to the selection of suitable tyres for the wheels. If the tyre is too large or too small, it is quite possible that it will not fit on the desired wheel rim. An unstable assembly like this can lead to dangerous situations while behind the wheel. If, for example, you already have wheel rims and simply need winter tyres, you should definitely take note of this and only choose tyres that match the size of your wheel rims. Also remember that: Only winter tyres with rims with special coatings are suitable for use in mud and snow.
