Question:

How to know heat rating?

asked by: Eddie

Helpful Expert Reply:

Trailer tires like the Westlake ST205/75R14 Radial Trailer Tire # 274-000012 are not given heat ratings. The heat ratings are something that is given on passenger car/truck tires as a requirement by government agencies.

Trailer tires are not subjected to the same kind of wear and tear as other tires. While it is important to ensure the tire is not overheating which is usually caused by underinflation and misalignment of axles, they do not receive heat ratings.

I always recommend using a tire pressure and temperature monitoring system like the TireMinder # TM89FR to monitor the pressure and temperature of the trailer tires while driving as when spikes occur they device can alert you to the possibility of a blowout before it occurs.
