Are 4Ply Bias Trailer Tires as Strong as 6 Ply Trailer Tires of the Same Size

Question

Question:

I have 6 ply tires on my small pull behind motorcycle trailer. Would a 4 ply be a better tire to use when the total weight of trailer and gear is 300 pounds? Is the 4 play as tough against punctures as the 6 ply?

Expert Reply:

The higher the ply rating, the tougher a given tire size is going to be. I would stick with the tires that are recommended by the trailer manufacturer. A tire that is rated lower but the same size can wear out faster because of its lower capacity. Ideally you will want the tire capacity for an axle to meet or exceed the axle capacity (the capacity of the trailer does not increase if the tires exceed the axle capacity).

Trailer tires should always be inflated to the maximum psi rating as indicated on the tire. Because trailer tires are made with a thicker sidewall than passenger vehicle tires, if they are under inflated they will build up excessive heat and can fail. I have included a link to our FAQ on trailer tires for you.

Answer 1

Yes. Kenda recommends running their tires at the max psi when inflated cold no matter the weight on the trailer. The good news is a tire with load range B is going to be softer than a higher ply/load rated tire. Goodyear is the only manufacturer we…

Answer 2

Load Range for trailer tires has to do with the weight capacity. The higher the Load Range the higher the weight capacity and usually the higher the PSI recommendation for the tire. Going with a higher Load Range will not give you the ability to…

Answer 3

Yes, the trailer wheels part #AM20027 that you referenced can easily handle 70 psi. The recommended valve stems for this wheel are part #AM20904 which are rated for up to 80 psi as well.

Answer 4

You just need the valve stem that is associated with wheel #AM20539 for a proper fit. In this case it is valve stem #AM20904. This valve stem presses into the hole so that the larger diameter end won't allow it to pull out of the wheel. I have…

Answer 6

The load range tire used is going to depend on the gross trailer weight capacity, which should be on a sticker or plate near the front of the trailer frame or in the trailer's literature. It probably also indicates the load range, or at least the…

The Loadstar 4.80-12 Bias Trailer Tire with 12" Wheel #AM30670 does come with a galvanized wheel that has a silver color to them. The design of the galvanized process gives it a rough texture instead of a smooth texture like you see with…

Answer 8

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Answer 10

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 like…

Answer 11

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…

Answer 12

The difference between the Class II and Class III hitches has to do with their Gross Trailer Weight (GTW), their Tongue Weight (TW), and their Hitch Receiver Size. Class II trailer hitch receivers have a 1-1/4 inch receiver and can be rated up to…
