With these components, the 2018 X5 xDrive35i delivers stable highway manners and a sportier feel than many competing SUVs, especially when equipped with performance‑oriented suspension options.

Wheels, Tires, and Towing Capacity

The X5 xDrive35i was offered with a range of wheel sizes, from comfort‑oriented 18‑inch wheels to aggressive 20‑inch and larger designs. Towing capability is substantial for a unibody luxury SUV.

• Roof load capacity: Typically around 165–220 lb (75–100 kg), check market-specific data

Larger wheels enhance appearance and cornering feel but can reduce ride comfort and marginally affect fuel economy, so buyers often chose based on their balance of style and comfort needs.
