My friend I was with told me it wasn't too bad because it isn't anywhere near as deep as the treads and once I break I'm the tire, I shouldn't have rubbing at all. Is the correct? I was going to go up to Putnam to have you look at it, but my significant other didn't want me riding an hour by my self.
Well, once the metal wears away the rubber that's hitting it (or you wear the tire tread down with enough use), it won't rub anymore, since there won't be anything left there to rub.

Keep in mind that as long as you have grooves visible like that, the metal is riding in that little carved out channel in the tire. If the tire's shape changes (due to increased speed, lean angles, etc.), it could put nearby rubber in contact with the metal instead. It's not going to completely lock up the rear or anything, but just remember that it could rub more under more extreme circumstances, which is generally when you want the least amount of surprises.

It doesn't look too deep. I wouldn't expect it to cause significant damage to the tire. But keep an eye on it to make sure, and don't forget that as long as you have tread higher than the bottom of the groove, the tire could still rub.

If the tire is rubbing on the swingarm, changing the shock will have absolutely no effect on that.
