The particular load range of trailer tire needed for any given application depends on the number of axles and tires. If a trailer were to have, for example, two 3500-lb-rated axles, then it would likely have a gross weight rating (GVWR) of about 7000-lbs. In this example it would be appropriate to use 4 tires rated for Load Range D, such as # TA24VR. This wheel/tire combination is rated for 2540-lbs at its specified 65-psi pressure. For your trailer that has a GVWR of 7K, these tires would provide an excellent safety factor.

Basically make sure the total combined weight capacity of all the trailer's tires is greater than the trailer GVWR.

Most trailer tire sizes are available in more than one Load Range. It is best to choose tires that provide some safety margin, more capacity than the trailer actually requires, as a way to reduce the chances for a stress-related blowout.

The best ways to protect trailer tires from failure are to 1) maintain correct cold inflation pressure; 2) operate the tire within its speed rating; 3) operate the tire within its weight load rating; and 4) protect them from damaging UV exposure by using tire covers.
