New user, first post... Have a 300 mile round trip on a 2015 fxdwg to a swap meet in town then a ride up the canyon to the inlaws for dinner. Mostly ride highways in town and just noticed the center of my rear tire seems seriously worn out. Obviously a tire change is in my plans for monday but the million dollar question is the tread too low to be safe tomorrow? Thank you for responding in advance, apologize of its a dumb question.

 

Ride it, I would.

Would I ride it 80mph on the highway in a frog strangler rain storm with standing water on the road? Probably not.

 

in dry conditions, absolutely.

 

 

Crap, I'd take off across country on that one and not be too concerned. Seems you have plenty left on the shoulders... what's up with that?

 

Get it replaced as soon as you reasonably can, just ride with great care. Once a rear tyre gets down to that level of wear they can, in my experience, start to get a bit squirrely, which is the time to change. I suspect I would have changed that tyre recently, if it were on my bike.
