How much weight can trailer tires hold?
Load Range Most boat trailer tires fall under C or D. If boat trailer tires hold a C Load that means it can carry up to 1,820 lbs. On a single axle trailer this means that the boat trailer tires can support up to 3,640 lbs.
What PSI should trailer tires be?
between 50 and 65 psi
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.
What should utility trailer tires be inflated to?
What psi Should Trailer Tires be Inflated To Trailer tires should always be inflated to the maximum air pressure indicated on the tire. The tire on tire and wheel combo #AM30620 for example should be at 90 psi.
What are the load ratings for trailer tires?
Special Trailer Service Tires
| ST-Metric Trailer Service Tires | ||
|---|---|---|
| Load Range | Ply Rating | Maximum Load Pressure |
| C | 6 | 50 psi (350 kPa) |
| D | 8 | 65 psi (450 kPa) |
| E | 10 | 80 psi (550 kPa) |
What load rating do I need for trailer?
To find out what your tires’ load carrying capacity minimum needs to be, simply divide the trailer’s GVWR by the total number of tires (in our example: 10,000/4 = 2,500). Luckily, trailer manufacturers almost always include tires that (when combined) exceed the trailer’s GVWR by a fair margin.
How do you calculate trailer load capacity?
Payload capacity refers to the total weight capacity of your trailer. You can calculate maximum payload capacity by subtracting the trailer weight from the GVWR. Tongue weight is the amount of your trailer’s weight that transfers to your tow vehicle through the trailer’s tongue or gooseneck.
Should trailer tires be balanced?
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.
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. Not only do you get the full capacity at the max psi, you also will generate less heat in the tire since there won’t be as much flex in the sidewall, you’ll get better wear and better fuel mileage.
What is the highest load range for a trailer tire?
This article focuses on 14 ply trailer tires (load range G), which is the highest capacity you can get. 14-ply rated trailer tires can sustain pressures of up to 110 psi (760 kPa), and weight of over 4,000 lbs per tire.
What is the load capacity of a trailer tire?
Generally speaking, trailer tires have a Load Range of either B,C, or D. For example, a trailer tire with a load range C can hold 1,820 pounds. This means that if you are hauling a boat on a trailer with a single axle (meaning two tires are carrying the weight) then the total load capacity is 3,640 pounds*…
How much weight can single axle trailer tires carry?
You see, single axle trailer tires can carry 100\% of the load rating. So, if your trailer tires have a load range of C, then they can safely carry 3,640 pounds (depending on the tire manufacturer’s specifications).
What is the maximum weight for a utility trailer?
When fully loaded, a small enclosed utility trailer can be rated for a maximum of up to 7,000 pounds (GVWR). However, for trailers 12 feet long or less, the average cargo load capacity is typically around 2,200 pounds.
What is the maximum load range of a double axle trailer?
This means that if you are using trailer tires with a load range of C on a double axle trailer, then the maximum load range is 6,406 pounds. Additionally, the psi of the tires goes up as the load range increases.
