Question:
Loadstar 4.80-12 DOT 20B5 U12 on 5X8 flatbed trailerMGW 1500lbs.

Expert Reply:
In order to determine the specific cold inflation pressure of your tires, I will need to know the load rating of the tire. The load rating or load range designation should be stamped on the tire.
We carry two Loadstar 4.80-12 tires, a load range C tire, # AM10062, and a load range B tire, # AM10060. The inflation pressure will be different based on the load rating. The load range C tire can support a maximum load of 990 lbs at 90 psi and the load range B tire can support 785 lbs at 60 psi.
If you can tell me the specific load rating or weight capacity of your tire, I can give you a more accurate inflation pressure.

Hi John........my tirees are loadstar. Load range C. That said, I have a 14' fiberglass boat and 15hp motor. Not too heavy....maybe 500 lbs. My tires are registering about 15lbs. I was concerned about over inflating. Any suggestions? Thanks,
