The tires on my Cobra trailer from the factory are marked
185R14C8PF (102/100N)LT

They appear to be GT Radial Max Miler X
Load Range D 1875 lb at 450KPA 65# cold

They need to be replaced, and the local tire stores seem to be having
an issue identifying the correct replacement. A brief web search has
also been unsuccessful.

Any advice on the correct replacement, or where to find the code for
reading the markings would be appreciated.
