How can you determine if your tires are being operated under a fire service rating?
You can determine if your tires are being operated under a fire service rating by checking the maximum load rating listed on the sidewall of the tire.

If the GAWR rating divided by its tires is greater than the sidewall rating for the tire, then your tire is operating in a fire-service condition.
