I think it was $20 last year he charged me to changeover to the winter wheels/tires. My time is more valuable than that, so to me it is absolutely worth it to just let him do it while he has it for regular service. In the spring I needed new all-season tires, so just paid for the tires and mounting on the summer wheels. In a sense you could say that time it was free to change the tires since there was no additional cost specifically for that.
I quoted tires alone locally and it would have been $700 plus $75 to swap over twice a year. So to buy new rims and tires was $900 from tire rack. They had way better prices on the tires and having the convenience of doing when I wanted.
