That is what is referenced on the back of the wheel, same casting but with 5 or 6 lug holes. https://www.tredittire.com/wheel/altitude/ |
I was responding to this information:
It says:
MAX LOAD
2150&6/2830LBS
If that information is actually on the wheel, it's official and supersedes brochure information.
I used a load inflation chart for tires ST225/75R15 because the 2150 above equals a maximum loaded LRC tire for that tire size, as does the 2830 for a LRE.
Load index numbers do not provide the official load capacity for ST or LT tires. They conform to the load range lettering system. However, you'll find load index numbers on the LT & ST tires because sections of that system are official for all tires. Those sections may be a maximum load capacity when the tire is used in a dual configuration (114/110, the 110 is maximum load for dual configuration). The load index system also provides a speed letter after the load index which is official (114/110L, The "L" is the letter for 75 MPH).
Some "off shore" ST manufacturers may depict actual values on the tire sidewalls. It is also official.
