The Karrier ST235/85R16 Radial Trailer Tire # AM10501 would certainly have enough capacity for your 7000 lb axles since it has a 3,960 lbs when inflated to 110 psi. Special trailer tires should be inflated to their maximum air pressure. At the maximum air pressure, the tires will perform and wear best, and get the best gas mileage.
If a trailer tire is inflated to a lower air pressure than the maximum, the amount of weight that the tire can carry will be reduced. If a heavier load is put on the trailer tire than what is recommended for that air pressure, the sidewall of the tire could heat up and cause the tire to fail.
If you are experiencing a lot of blowouts that is either caused by overloading the tires, by exceeding the speed limit for the tires as this causes excessive heat. Unless otherwise stated trailer tires are rated at 65 miles per hour, or by having the tires under-inflated.
Special trailer tires are usually rated to operate at a maximum speed of 65 mph. If you exceed 65 mph, heat could build up in the tire and cause it to break down and fail. If a tire is rated to run at a higher speed, this information should be listed on the trailer's sidewall.
