The three radial special trailer (ST) tires we offer in size 215/75-14 can be seen on the linked page. These include the Taskmaster # TTWTRTM2157514D in Load range D, the Provider # TTWTR21514 in Load Range C and the Kenda Karrier # AM10229 also in Load Range C. All of these radial special trailer tires will provide more flex for better ground contact than a bias ply tire.

The main difference between these tires, apart from their load range ratings, is their speed rating.

Trailer tires are nominally rated for 65-mph maximum speed unless specifically stated otherwise. This is important because if a tire is operated above its speed rating it will become hot and this heat can lead to early deterioration of the tire and its failure.

The Provider and Taskmaster tires carry a M speed rating, indicating they can be safely operated up to 81-mph as long as they are inflated properly and used within their rated load capacity. For highway use where speed limits can often exceed 65-mph, the Provider or Taskmaster tires are clearly the better choice.

Trailer tires should ALWAYS be inflated to their maximum psi pressure rating as noted on the tire sidewall. It is never appropriate to over- or under-inflate a trailer tire.

Answer 1

Assuming your trailer wouldn't need the capacity of the higher Load Range and you could use the LR C or LR D I'd go with the #AM10235 over the #TR20514 as it has a longer warranty at 5 years when compared to 2 years.
