Bakdäcken

Bakdäcken, commonly known as rear tires, are the tires located on the back wheels of a vehicle. In most passenger cars, trucks, and motorcycles, these tires play a vital role in providing traction, stability, and load-bearing capacity. While front tires mainly steer the vehicle, rear tires are responsible for transmitting power to the road surface in front‑wheel‑drive configurations, while in rear‑wheel‑drive or all‑wheel‑drive cars they carry the majority of the propulsion force.

The performance of bakdäcken is influenced by factors such as tread pattern, rubber compound, rim size, and load rating. Modern rear tires often feature asymmetrical tread designs that enhance cornering grip and improve water drainage, reducing hydroplaning risk. For touring and long‑distance driving, the rear tread may be optimized for longevity and reduced rolling resistance, while high‑performance models may employ softer compounds to maximize rubber‑road contact.

Compared to front tires, bakdäcken are usually specified with a higher load index to accommodate the heavier load distribution over the rear axle in many vehicles. In heavy‑duty trucks and vans, the rear tires can bear significant portions of cargo weight, and are therefore manufactured with reinforced sidewalls and thicker carcasses. These characteristics also make rear tires critical components in safety systems such as anti‑lock braking and electronic stability control; abrupt changes in traction at the rear can lead to oversteer.

Maintenance of bakdäcken involves regular monitoring of tread depth, pressure, and alignment. Properly inflated tires help maintain optimal contact patches, while uneven wear can indicate suspension or steering issues that may compromise vehicle handling. Regular inspection of the rear tires also reduces the risk of sudden failure, ensuring that drivers can rely on consistent performance, especially in adverse weather conditions.
