Unless otherwise noted trailer tires are rated as 65 miles per hour as their max speed. Exceeding the speed rating will cause the tire to heat up and fail easier. The Taskmaster radials like the part # C22515D which is an ST225/75R15 like you mentioned has a speed rating of 81 mph.Correspondingly, what is the speed rating for a trailer tire?
65 mph
Similarly, what are ST trailer tires? Special Trailer Tires Special Trailer (ST) tires are designed for your trailer's requirements. Their stiff sidewalls help prevent your rig from swaying. Their heavy-duty load capacity is critical; ST tires have 10% more load capacity than equivalent light truck (LT) tires and 40% more than passenger car (P) tires.
Moreover, what PSI should my trailer tires be at?
Boat-trailer tires require a lot of air pressure — in most cases, between 50 and 65 psi. In fact, the correct tire pressure for your boat trailer is almost always the maximum-rated pressure for that tire, which is molded right on the sidewall. Maintaining that trailer tire PSI is critically important to towing safety.
Can I use a car tire on a trailer?
An "LT" tire is the same rating as "ST" and can be used as such. Passenger car tires can be used, but the weight ratings are less. As far as I know, it is not illegal to use a passenger car tire on a trailer. Its not recommended, but it is legal.
Are radial tires better for trailers?
Radial tires, however, do perform better than bias tires, and that performance is quickly noticeable. The ride is smoother, the trailer does not bounce and sway as much, and radial tires have a longer life. The most important characteristic of any trailer tire is its ability to carry a heavy load.Do you need to balance tires on a trailer?
Since the primary duty of a trailer tire is supporting a vertical load, rather than gripping an automobile through turns, trailer tires do not have to be dynamically balanced like passenger car tires do. Steering and cornering are less of a concern on a trailer tire than they are on an automotive tire.How much weight can a Load Range E tire carry?
The Load Range C BFGoodrich tire (manufactured by Michelin) is rated at 2,470 at 50 psi and weighs 44 pounds, while the same tire in Load Range E is rated at 3,195 pounds at 80 psi and weighs 52 pounds.How do you find the load range on a trailer tire?
To find the load range of your trailer tire, look at the sidewall and on there you will find the lowest and highest end of the load ranges. You will find a Load Range value of either B, C, D, or E. Load Range B is the lightest load the tire can carry and Load Range E is the heaviest load it can carry.What is the highest load range for a trailer tire?
Expert Reply: The highest-rated 16-inch trailer tire we offer is the Load Range G Provider ST235/85R16 Radial Trailer Tire # TTWPRG235R16. This tire's maximum load capacity is a whopping 4080-lbs at 110-psi cold tire pressure when used in a single-tire application.Are H rated tires better than T rated?
Generally, the higher in the alphabet a tire is rated, the better it will manage heat and faster speeds. There's an exception for the H rating; read on for why. Your actual speed capacity may be less than a tire's rating. Most winter tires have Q, S or T speed ratings.What happens if you exceed tire speed rating?
The speed rating is there to let you know that you shouldn't exceed that speed with that tire. If you do for a sustained period of time the air in the tire will heat up and expand causing the tire to explode.What is Load Range E?
The load range is identified by a letter of the alphabet, usually from A to F, which represents the ply rating and load pressure. A rating of "E" on the tire means the tire has a ply rating 10 and a load pressure of 80 psi.Should I inflate my trailer tires to max psi?
When it comes to trailer tires you always want to have them inflated to their max psi when cold. Unless otherwise stated trailer tires are not rated to exceed 65 miles per hour. If you exceed 65 mph, heat could build up in the tire and cause it to break down and fail.How hot is too hot for trailer tires?
When we trailer, we check the tires and hubs everytime we stop with a heat sensor gun thing. The tires typically run between 130 and 135 F and the hubs are about 125. There is a difference on the tires between the sidewall and the treads, with the treads usually running about 5 degrees hotter.At what PSI will a tire explode?

What should I inflate my trailer tires to?
Trailer tires should be inflated when they are cold and should be inflated to the max psi rating on the sidewall. In your case you would want to run 80 psi. If you don't inflate them to the max psi figure you will lose weight capacity and…Should tires be inflated to max psi?
RAY: Under no circumstances should you inflate your tires to maximum pressure. Not only will you risk a blowout, but you'll diminish your ability to control the car because your handling and braking will be much, much worse. TOM: Not to mention the ride!Is 44 psi too much?
In other words, the 44 psi you refer to is the maximum inflation of the the tire at its maximum load rating. Since you've not given us information about the type of tire or the vehicle, I will say to use a pressure 10% to 15% under the maximum psi rating to get the best performance of the tire.Why do trailer tires wear out so fast?
That said, rapid or significantly uneven trailer tire wear can be caused by: Riding with the wrong tire pressure. Exceeding your tires' load capacity. Trailer misalignment or bent wheels from hitting curbs, potholes or debris.How long do tires last on a trailer?

If tire pressure is too high, then less of the tire touches the ground. As a consequence, your car will bounce around on the road. And when your tires are bouncing instead of firmly planted on the road, traction suffers and so do your stopping distances. You'll also feel a decrease in ride comfort.
