This is something that I've debated guys on before in the past. What should be done with a full-sized macthing spare? Some people think that it should be rotated into the normal pattern of rotation every 5k, thus giving extra life to your tires (in theory). Others say don't touch it becuase it's a hassle to get it put onto a new rim and a hassle to have one on a rim moved to the spare rim. Anyhow, what's everyone's opinion on this?
