Not sure if anyone has experienced excessive tire wear on their Q70, if not, happy for you! I’m on second set of tires, and had to replace two more yesterday, and car only has $42,500 miles! Wear is happening on the inner edge of year tires. This is caused by factory camber angle of rear axle. My tire guy and I agreed to set it outside of factory specs and basically run tires straight up and down, as well as rotate every 4,000 miles. Will Follow-up on how wear is in 4,000 miles!
