I scheduled oil change service prior to a road trip, and was seriously considering buying new tires due to a right pull on the vehicle (2015 Equinox). After discussing the situation with the service rep, he pointed out that tire rotation was complimentary and suggested a certain sequence might be helpful. I was hesitant because I was fearful the pull would worsen just prior to a long drive. When he offered to put it back if the pull increased no charge, I said go ahead. Guess what? The pull was gone and I was happy!
