Most likely yes. The 55 or 60 in this case is the aspect ratio. It’s how tall the tire is as a percentage of its width. A 60 means the tire’s sidewall height is 60% of the width of the tire.

Can you tow with D rated tires?

For driving unloaded it would be fine. If you are running much lower than the >tire< rated psi then yes. D or e rating makes little difference aside from being an old way of rating tires but is a quick reference. The load index rating can be higher on d rated tires than e rated based on tire size.
