All trailer tires must always be inflated to the specified maximum cold psi pressure as noted on the tire sidewall. Tires should never be under- or over-inflated at any time as this can lead to heat build up, uneven tread wear, loss of weight capacity or a blowout. A trailer tire cannot meets its load rating unless it is inflated to the cold tire pressure noted on the sidewall.
Usually an under-inflated tire will wear more on the outside edges of the tread surface; an over-inflated tire... view full answer...
When a tire wears more on its inside and outside edges more than it does in the center of the tread this usually indicates that the tire was under-inflated. If a tire wears more in the center than on its outsides this usually indicates over-inflation.
All trailer tires, no matter their type, size or weight rating, should always be inflated to the cold psi pressure indicated on the tire sidewall. It is never appropriate to under- or over-inflate a tire for a specific load or driving conditions.... view full answer...
No you should not inflate your trailer tires to over the maximum psi; if your tires have a max of 35 that should be what they are inflated to as going over could also cause the tire to wear in the center of the tire quicker than it should.
Underinflated tires is a potential cause for your tires wearing on the outside but it might also be an issue that the weight on your trailer is not enough to straighten the axle when under load. Trailer axles have a slight bow to them that straightens... view full answer...
The wear is going to be the same with a bias tire or with a radial tire so changing out the style will not help with what is causing the wear. If the tires were over inflated, the center treads would wear. Under inflated tires would show wear on the inside and outside treads. If the wear is just on the outside then the tire is riding at a slight angle with the bottom pointed more in toward the trailer than the top.

Having the center of the tire tread wear more than the edges is typically a sign that the tires have been over inflated. Since you've mentioned that the tires are correctly inflated, we'll need to look elsewhere. This can also be caused by the tires being overloaded, but it's more likely been caused by worn suspension components. Make sure all the hardware on your suspension is still tight. Take a look at the shackle straps, the holes that the bolts pass through should be round, not elliptical... view full answer...
The most common cause for trailer tires' tread to wear more on their inside edge than their outside edge is overloading of the trailer. If a trailer axle is overloaded it's center will bend down toward the road surface and this will change its geometry, causing the inside edges of the tires to make more contact with the road surface than the outside edges. This will lead to uneven tread wear with more wear on the insides.
Please see the linked diagram.

It does sound like a possible overload situation. It is also possible that if you went up on a curb or something similar hard enough while loaded it could have caused the same problem.
You will want to inspect the trailer suspension. You will be looking for signs of were, worn, or corroded parts. Egg-shaped holes instead of round holes in the shackles or hangers indicates they need to be replaced.

There are several possible reasons for tires to wear that quickly. A bent or damaged axle, damaged or worn suspension components (like leaf springs, shackle straps or equalizers), an overloaded trailer or a tire being loaded above and beyond its load rating, improper inflation and exceeding the speed rating of the tire can all cause the premature tire wear you mentioned.

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... view full answer...
When you get wear just in the center tread of a tire that does indicate that the tire is over-inflated.
You want to make sure the tires are inflated to the max psi listed on the sidewall of the tires. Over-inflation would cause the wear and then could lead to the failure issues you are having.
If you jack up a side of the trailer do the wheels turn easily without any in/out or tilting movement? If so, the bearing are fine. view full answer...
Pressure wise you are fine. You always want to keep trailer tires inflated to their max psi. Inflating them when they are cold is recommended even though the pressure will increase as they warm up.
Typically failure is related to heat build up which can come from under-inflation, overloading, or exceeding the speed rating for the tire. Most trailer tires are rated at 65 miles per hour as their max speed so you would want to check the sidewalls of the tire.

Trailer tires can blow for a few reasons. If the trailer is overloaded that can do it. The combined capacity of the tires needs to be greater than the gross trailer weight. Exceeding the speed rating can also create excessive heat build up and lead to failure.
The other common issue is under inflated tires. Trailer tires should always be inflated to the maximum psi indicated on the tire. This is because trailer tires are built with a thicker sidewall than passenger vehicle tires to handle... view full answer...
Typically trailer tires fail for the following 3 reasons.
1) Keep your tires fully inflated to the maximum pressure listed on the tire sidewall. Unlike a passenger car tire, trailer tires feature a stronger sidewall designed to provide greater stability when under load. Failure to fully inflate the tires can cause heat build-up, leading to premature tire failure. Also, a tire only will only realize its specified load rating when inflated to its maximum psi shown on the tire.
2) Do not... view full answer...
A lot of trailer tire blowouts are a result of heat build up that causes the tire to fail. There are several things that can cause too much heat to build up but the main two most likely suspects are overloading the trailer and/or under inflated tires.
The trailer axle capacity should be located on a sticker or plate on the frame. Avoid loading the trailer beyond its capacity and use tires with an appropriate weight carrying capacity. Trailer tires should always be inflated to the maximum... view full answer...
I first recommend checking to make sure the tire is properly inflated to the maximum psi listed on the tire's sidewall. If the tire is under-inflated, the sides of the tire tread will wear quickly.
If the tire is inflated properly, then it's very possible that there is an issue with the trailer's suspension components or axle/spindle. Since the wear you noticed is only on the outer edge of the tire, this might indicate that the spindle is not parallel to the ground. There could be a suspension... view full answer...
Special trailer tires should always be inflated to their maximum air pressure (in this case, 80 psi). Manufacturers test their tires to determine the optimal inflation level, and 80 psi is common for 12” trailer tires, so inflating to 80 psi won't cause a blowout in itself.
The most common cause of tire blowout is overheating. Overheating can be caused by several different factors:
-Overloading the trailer. If the load range of the tire is exceeded by the weight of the trailer, this... view full answer...
Tire failure is usually caused by a few things. It can be from overloading the trailer, improper tire inflation, and/or exceeding the speed rating for the tire.
You should verify that the tire capacity you have for you trailer is adequate for how much your trailer weighs.
The pressure ran in the tires makes a big difference in longevity too. ST tires should be ran with the full pressure rating stated on the side of the tire, for full load capacity and longevity of the tire. If lower pressures... view full answer...
If any of the components were bent or damaged there is a chance that the bent parts could be causing the irregular tire wear that you are seeing. If a component was bent you would usually see tire wear on the inside or the outside of the tire depending on which way the part is bent.
More than likely the tire wear is being caused by the amount of air in the tires. If the tires are over inflated, then typically you would see more wear in the center of the tires. If the tires are under inflated,... view full answer...
What probably occurred was excessive heat build up like you have said. Trailer tires are made with a thicker side wall. This thicker side wall is made to handle more vertical load associated with trailers. If a tire is under inflated, this will allow for excessive heat to build up and the tire will not be able to cool down like normal. This is when you get blowouts.
The solution is easy. Make sure that you inflate the tires to the maximum psi rating as indicated on the tire. For the Karrier... view full answer...
Typically when you have wear just in the center tread of a trailer tire it is due to the tire being over-inflated. With that being said it sounds like you are properly inflating them to the maximum 60 psi that is listed on the tire sidewall so this doesn't appear to be the issue.
Another factor that might lead to the center wear is heat builtup on the tire from exceeding its speed limit. Unless otherwise indicated on the sidewall, trailer tires will have a maximum speed limit of 65 mph.... view full answer...
