What is the tire pressure for 235 80R16 trailer tires?
For ST235/80/R16 trailer tires rated 129N, cold tire pressure should typically be around 65-80 PSI to support heavy loads safely. Check the tire sidewall for maximum PSI ratings and never exceed axle weight limits (7000 lbs each). Inflate tires when cold—before driving—to get accurate readings. PSI applies to unloaded driving conditions. Increasing it to 40-45 is a good practice for towing and carrying loads.No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they’re carrying heavier loads or if the manufacturer’s recommendation is close to that figure. However, it’s generally too high for most passenger cars, which usually recommend between 30-35 psi.PSI applies to unloaded driving conditions.

What is the difference between 235 80R16 and 235 85R16 trailer tires?
The 235/85R16 tire is just about 1 taller in diameter than your existing 235/80R16 tires, but only half of this difference will actually affect the trailer height (since the other half is above the axle). This means the new tires will only raise the trailer about a 1/2 at most. The difference is overall diameter. The 235/80-16 is 30. The 235/85-16 is 31. A difference of 0.The first part of a tire code indicates the tire’s dimensions. The number 225 represents the section width, the width of the tire in millimeters, while 75 refers to the aspect ratio, which is the height of the tire’s side wall as a percentage of its width. R: Radial (Tire’s Construction).R16 Tire Size Explanation In this case, the tire’s width is 235 mm (9. The aspect ratio is expressed as a percentage of the tire’s height to its width. A 75-aspect ratio means that the tire’s height is 75% of its width (in this case it is 176.
What psi should I run my trailer tires at?
Check tire pressure before you use your trailer. Keep your tires inflated to the maximum PSI branded on the sidewall. 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.Boat-trailer tires require a lot of air pressure — in most cases, between 50 and 65 psi — and having the wrong tire pressure increases your chances of a blowout or other performance issues while towing.Underinflation: The leading cause of blowouts. Underinflated tires generate excessive heat, leading to structural failure. Overloading: Exceeding the trailer’s weight capacity puts immense stress on the tires, increasing the likelihood of blowouts.Should trailer tires be inflated to max PSI? Trailer tires should be inflated to the maximum inflation designated on the tire’s sidewall to reach full load carrying capacity. Remember, the air within your tire is actually carrying the weight!Inflate tire to the Trailer Manufacturers recommended Cold Tire Inflation Pressure or to maximum of 550 kPa (80 psi).

Are trailer tires stronger than regular tires?
Fundamental Design Differences Trailer tires prioritize completely different performance characteristics. Their primary function is supporting heavy loads with reinforced construction and stiffer sidewalls. They’re engineered to track straight and resist swaying, not to handle sharp turns or sudden direction changes. Trailer tires are different in that they do not power or steer your car. They are also designed to dissipate heat due to the weight they carry, which can be much more than a standard passenger tire. Trailer tires also operate at higher air pressure than passenger tires.They are also typically speed rated to 65 mph max so highway speeds are perfectly doable. We recommend looking at our blog on the truth about trailer tires for more information! Safety tip: always make sure your trailer tires are aired up to their maximum rated pressure (you can find this on the sidewall).Bias-ply models are the thicker tires for trailers. This is due to the angled ply placement of the tire’s construction, which provides better load durability and damage resistance.Sidewall Construction: Trailer tires often have stiffer sidewalls to support their load better. This feature helps prevent sidewall flexing, which can lead to overheating and tire failure.
Is 90 PSI too high for trailer tires?
The psi will actually increase some during travel due to heat build up but the manufacturer has already accounted for this. The 90 psi rating is actually normal for that size tire. For example, the Taskmaster 4. Trailer Tire # TT48012C has a Load Range of C which means 990 lbs at 90 psi. Load Range C: 6-ply rating, a common choice for medium-sized trailers. Load Range D: 8-ply rating, suitable for larger trailers or heavier loads. Load Range E: 10-ply rating, often used for heavy-duty trailers or commercial applications.In the chart above, tire load ranges are arranged from A to G. A is equivalent to a 2-ply rating, while C equals a 6-ply rating. That ply rating (load range), when combined with the tire size, can tell you the load capacity. The higher the ply rating, the higher the carrying capacity.For example, a tire with a load range C can typically carry a maximum weight as high as 1,870 pounds at 50 PSI, while a tire with a load range G can carry a maximum weight as high as 4,400 pounds at 110 PSI.C and D load range tires are the most used when it comes to medium to larger-size trailers, but if you’re hauling a heavy-duty trailer, load range E tires are probably what you need.
