8x18 rims

8x18 rims: a dynamic size for high-performance vehicles

8x18 rims are a popular choice for sporty compact cars, saloons, coupés, estate cars and mid-size SUVs. The size specification refers to a rim width of 8 inches and a rim diameter of 18 inches. The greater width often allows tyres with a correspondingly wide tread to be fitted, which can give the vehicle a more powerful appearance.

When combined with a lower tyre profile, 18-inch rims often provide a more precise steering feel and direct feedback from the road surface. At the same time, ride comfort may be slightly firmer compared to smaller rim sizes. Whether an 8x18 rim is suitable for a vehicle also depends on bolt circle, offset, centre bore, load capacity and approved tyre size.

Alloy and steel rims in 8x18

The range in this size consists almost entirely of alloy wheels. Alloy wheels are available in numerous designs and are particularly well-suited to personalising modern vehicles. Popular choices include sporty double-spoke designs, concave five-spoke wheels and finely detailed multi-spoke designs.

The range of finishes extends from classic silver through black and anthracite to bronze or polished variants. For year-round use, winter-suitable alloy wheels with durable coatings are also available.

Steel rims are only available in 8x18 for rare specialist applications. Due to their large diameter and wide profile, they play virtually no role in the standard passenger car aftermarket. Anyone looking for a robust winter solution therefore usually opts for specially coated alloy rims.
