18x8 is one of the most common wheel size combinations we carry — 4,707 wheels in stock at this exact diameter and width. A 18 inch wheel with a 8 inch rim takes 225 to 245 mm tires, which is the range most 18 inch fitments are built around.
This combination shows up most often in 5x114.3, 5x112 and 5x120, so if you already know your bolt pattern you can go straight to that page instead. Width is what decides your tire: a 8 inch rim that is too narrow for the tire bulges the sidewall, and one that is too wide stretches it and exposes the rim edge to curbs. Stay inside the tire maker's recommended rim range and the 18 inch wheel will sit square.
Offset is the other half of the fitment. The same 18x8 casting is usually offered in several offsets, from a factory-flush fitment to a deep-dish stance offset, and they do not interchange — pick the offset your vehicle needs before you pick the finish. Free shipping in the US on orders over $59.
