Here are a few tire options that would be suitable for a BMW X7 on 22" wheels: - Michelin 255 70R 22.5 Xza is available for R4500. The Michelin Pilot Sport Xza is an excellent high-performance summer tire known for its predictable handling and precise steering response. - Pirelli P Zero 235/45R22 97V can be found for around R4500 as well. The P Zero is a popular ultra-high performance tire from Pirelli, delivering sharp handling and grip for an engaging driving experience. - Continental 245/40R22 103Y ExtremeContact DWS06 Plus retails for about R4500. As an all-season tire, the Continental provides steady traction in both wet and dry conditions throughout the year while still giving a comfortable ride.
