My current C-range tires are 26.5" diameter. I can't find D-range tires less than about 27.5" diameter. That would close the distance between the tires even more. I guess my question is this. How close can I mount my tires and still not worry about them touching while towing. I'm surprised that they came so close. Any input appreciated.
I'm not sure I understand your question here. Are you replacing the tires with the same size as your original tires?
If so, then Load Range/Ply Rating doesn't usually make any difference in the actual diameter.
Although there are some small diameter differences between tire brands/models, depending on how they measure the tire....it's usually fairly small.
What can affect the actual diameter, is wear. Are you measuring the diameter of the tires that you have currently on the trailer.........that will have less tread now since they are used......as compared to a new tire specifications on a chart?
