Questions about this item

How long will the 13/32-inch tread depth last under heavy daily towing?

Treadlife is not rated by the manufacturer, so mileage under sustained heavy loads cannot be guaranteed.

How much heat builds up in the 12-ply sidewall during all-day highway runs?

The all-steel construction and Load Range F rating are designed to dissipate heat at speeds up to 87 mph.

Will these tires fit my existing 15-inch trailer wheels without new rims?

They mount on any 15-inch rim approved for 225/75R15 Load Range F; the purchase includes tires only.
