According to the tire sealer I contactd a 185R14 is equivalent to a
195/75 R 14.  For my Van I called a Tire Warehouse and spoke with a very
nice gentlemen who sold me 4 Uniroyal 185R14's with a D load range
(8-ply), he said they were designed specifically for smaller Toyota
pickup camper conversions.  So far so good.
