My recommended first step for you to take is to determine what tire size you would need. If you check the plate on the trailer frame near the coupler there will the VIN, axle capacities, as well as the trailer tire size and Load Range recommended. Compare those specifications to the tires you currently have, if you don't have that recommended size and load range, those should be the tires you purchase.

The load range of a tire will be the capacity you need, and you can choose between bias tires, which are better for off-road or agricultural applications, or radial tires, which are better for highway driving.

When it comes to using a 8 ply versus 6 ply tire, having a higher ply will not make too much of a difference. They may give you a higher weight capacity but can eventually wear out just the same. You will always want to use tires that have a capacity that is best suited for your trailer. It is always recommended to use tires that are the same size, have the same load range and construction on a trailer. If tires are not matched you could have problems like overheating and overloading which can lead to tire failure.

You always want to make sure you inflate the tires when cold to the maximum PSI for the best performance. In order to achieve the maximum weight rating indicated on a tire the tire needs to be inflated to the maximum psi. Another factor is that trailer tires have a thick sidewall to handle more vertical load. When under inflated the thicker sidewall can generate excessive heat and lead to failure.

Also check your hauler to see if it is overloaded. If there is excessive weight it will cause your tires to run hotter and could result in a blown tire. Please ensure that you are not loading them with more weight than they (and/or your trailer axle) is rated for.

Exceeding the maximum speed rating of a trailer tire also makes them susceptible to blowouts. Please note that not all trailer tires with the same size will have the same load/speed rating. The sidewall of the tire will specify what the load range/speed rating is. For example the speed rating on # AM1ST90 is 65 miles per hour. Exceeding 65 miles per hour will also generate excessive heat.

Hey, thanks. You're not so bad yourself! Going to a larger tire size is possible but there are a few things to think about. Chief among these things is clearance. When going from an 8 inch tire to a 12 inch tire the diameter will increase by…

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13…

You will need to use the same ply tire on all sides of the trailer whether that be radial or bias(non-radial). If you were to use two different plies you could have two completely different tire temperatures and even pressures which would put you…

Answer 5

The main difference between a radial ply and bias ply tire is how the tire is constructed. The cords underneath the tire are run in different directions. On a bias tire, the cords run at a 32 degree angle from the direction of travel and on a…

As long as the 205/70-14 tires still have plenty of space between them and the fenders you an upgrade to a 205/75-14 tire like part #AM10256. The larger tire is the same width but it's about 3/4 of an inch larger in diameter so you need to…

90-95 ft lbs of torque is probably about right for your trailer rims. If you check out the lug nut torque chart that I attached you will see that nearly all of the torque specs are that and higher.

The best way to select a tire and the load range is by checking the weight rating of the axle on your trailer and making sure that the combined tire rating (2 tires for 1 axle) meets or exceed the weight capacity of the axle itself. In the…

Although a ST175/80R13 Radial Trailer Tire with a Load Range of C (1,360 lbs at 50 psi), like the Provider #TTWTRTM1758013C, does have a higher weight rating and psi rating than your current tire I don't really think it will be enough to…

Answer 11

The extra reinforcement does cause the Load Range E tire #AM1HP56 to be a little more stiff, but since you are comparing 205/65-10 size tires there won't be enough of a difference in how stiff it is to cause the ride to be drastically…

Answer 12

For a tandem axle trailer rated for 7000 lbs, you can use either a Load Range C or D tire. Each axle will be rated for 3500 lbs so you need a tire that will carry 1/2 that capacity. That would make your minimum load range before limiting your…
