Question:

So I just read the Q the person asked if the 117/112 was the psi and you of course said no. So my tires are the made in china 117/112L. Just so I understand: the 117 means the tire is rated at 2kand some odd lbs... per tire? So, my rigs GVWR is 8495, with 4 tires, I should be good there?? The L means dont go over 75mph. What does the 112 mean?

The 117/112L that you are seeing on your tire is in reference to the load range and speed rating. There is tire load index chart for light truck (LT) tires and the 117 corresponds to 2,833 lbs for single tires and the 112 corresponds to 2,469 lbs for dual tires. The L corresponds to speed rating L which has a max of 75 mph like you mentioned. Therefore, the above load range would be suitable for a tandem axle trailer with a gross vehicle weight rating (GVWR) of 8,495 lbs.

If you can let me know the size of your tires then I would be glad to make sure you get the correct replacements with the proper load range and speed ratings.
