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 is a good psi for trailer tires?
Boat trailer tires demand a high level of air pressure. When inflating your tire, the pressure gauge should show between 50 and 65 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. 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.
Is 80 psi too high for trailer tires?
Helpful Expert Reply: 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 potentially cause the tires to overheat and fail.
What should the tire pressure be on a boat trailer? – Related Questions
Can you over inflate trailer tires?
It’s really important not to overload trailer tires. Overloading tires can cause premature wear and increase the risk of tire failure. The “Max. Load” information stamped on the sidewall indicates a tire’s load capacity when it’s inflated to the maximum PSI.
Why do trailer tires have higher PSI?
This is simply because trailer tires are built with a thicker and stronger sidewall, enabling them to handle higher air pressure along with higher loads. The above mentioned Provider tire is an 8-ply tire with a 2,540 pound maximum load at 65 psi.
What is the recommended tire pressure for 65 psi max?
Under Pressure
In other words, if a tire reads “Max Load single: 3650 lbs at 65 psi cold” then 65 psi is the minimum cold-air inflation pressure necessary to carry the maximum load figure.
How do you calculate tire pressure on a trailer?
Divide your trailer weight (mine was 1800 pounds), by your maximum tire load weight (mine was 2720 pounds). The answer is the percentage of the maximum tire pressure you should have in your tires. (Mine was 66%.) Multiply your maximum psi rating by the percentage you came up with.
What PSI should I run in Load Range E tires?
Why do LT tires need more pressure?
Heavier body plies and larger bead bundles allow LT tires to be inflated to higher pressures, increasing the tire’s load capacity and allowing them to carry a heavy load continuously (not just occasionally) without overheating and failing.
What is Load Range E on trailer tires?
For example, a tire load range E rating means that the specific model and size can handle 1,520 lbs at 80 PSI. In other words, when the trailer or light truck tires hold the correct air pressure levels of 80 PSI, they can carry 1,520 lbs/tire.
Is Load Range E good for towing?
At a minimum, Load Range E tires are capable of safely supporting about 3,000 pounds. So, in the case of a dualie (six wheels), the tires collectively will provide more than sufficient grip for safely towing 18,000 pounds.
Will 10 ply tires help with trailer sway?
Some drivers with half-ton trucks also prefer to use a 10-ply tire for increased towing capacity. Higher load carrying capacity tires make towing easier because their stiffer tires help stabilize loads and reduce sway at speed.
Should I increase rear tire pressure when towing?
For towing, tires should be inflated to the max cold pressure listed on the sidewall of the tire. Even if you’re only towing half the weight your vehicle/tires are able to handle, half the max cold PSI DOES NOT support half of that maximum load, there’s a steep drop off of load carrying capability compared to pressure.
Do I need 10 ply tires for towing?
A 10 Ply tire rating or more is what classifies a tire as being towing-ready. In addition, using a tire with anything less than a 10 Ply tire rating is going to cause the tire to degrade at a faster pace and cause much worse high-speed stability.
How much weight can a 10 ply trailer tire carry?
Tire Weight / Tire Pressure = Load Capacity Pounds per PSI
At 80psi, a 265/75R16 10ply itire will carry 3,085 pounds of load. At 60 psi on a 10ply tire, the tire’s load carrying capacity is reduced to 2,314 pounds per tire. If the customer runs 65 psi in a 10 ply tire, his capacity is now able to carry 2,507 per tire.
How much weight can a 12-ply trailer tire carry?
Helpful Expert Reply: For trailer tires that are size 4.80-12 in a Load Range B like the part # AM10060 the weight capacity is 785 lbs at 60 psi. You should note that with trailer tires you have to have them inflated to their max PSI at all times to get the full capacity.
Are all LT tires 10 ply?
LT tires are usually 8-ply (Load Range D) or 10-ply (Load Range E). Passenger Tires usually have a 4-ply or 6-ply equivalent sidewall. The performance trade-off of this added weight is a harsher ride, less fuel efficiency, and less responsive handling.
What does LT stand for in a tire?
A tire size that ends with an LT means it’s a special kind of “Flotation Light Truck” tire that can also handle heavy loads and towing, but the tread pattern is engineered to prioritize off-road traction to “float” over sandy surfaces and loose sediment.
Are LT tires better for towing?
Light Truck Tires
Their “heavier” construction also makes them superior for hauling heavy loads and navigating rough terrain. Additionally, LT-metric tires often provide better handling when towing heavy equipment or supplies, which makes them a top choice for hardworking trucks and SUVs.
