I have a spare ST235/80R16E Westlake tire at home. So I checked this tire slightly to the right; as I was looking at the tire and down. There is 129/125L molded
in to the tire. This is the load and speed rating of the tire. The reason for the 129/125 numbers are if used in a dually application than the tire is rated at 125 at maximum air pressure of 110 PSI.
The L rating is the speed rating and is good to 75MPH if you want to go that fast!
There is also a letter designation for loading which is G and states a 14 ply tire.
Hope this helps?
