My local place installs them free if you buy the tires from them, They are a bit more, but not the difference in buying off the net, and paying for install. And I get to have my local place put a note on the ticket that customer will not accept tires older than 1 year. They order them in, call me, I make them verify dates, and then I take them off and to them. First time I let them do it all, never again, they lost an important washer / spacer, and I like doing other maintenance when the tires are off.
