RE: 'Ply Ratings' As far as I've been able to determine the "Ply Rating" system is no longer in use and hasn't been for some years now. It was a throwback to the old bias ply tires but was not a good or accurate way to describe radial tires that can be constructed a number of ways. Here is a page with a table that shows corresponding Ply vs the more current "Load Range" info: <http://flashoffroad.com/features/Tires/loadrating.html> and below that the more precise "Load Index" ratings. I haven't bothered to look but is anyone aware of any modern (current production) tires that even have a "Ply" number on the side? |
