I'm curious as to whether there is a noticable difference in the tire profiles that you are using. But I can't really see how your tires could have a 3 or 4mm difference between what Litespeed tested. It could be that tire pressure. The highest I ride at is about 130psi at the rear.
Also, at 210, I can't see you knocking wheels (unless they're very cheap) out of true unless you hitting things you should be going around. I'm 225 and haven't had any problems knocking a wheel out of true.
