What is the most common 15 trailer tire size?
The most common wheel sizes for trailer tires are going to be 15 and 16 inches. For this size wheel, the most common tire sizes include: st205/75r15, st225/75r15, st235/80r16 and st235/85r16. These sizes increase in both diameter and width and as they get larger the ply rating of the tire also increases. The most common wheel sizes for trailer tires are going to be 15 and 16 inches.

The rim diameter is the width of that well, measured from bead seat to bead seat—the spots where your tires grip the rim. This measurement is critical and must correspond exactly to the diameter of the tire being mounted. For example, a 16-inch tire must be paired with a 16-inch rim.The “4. In this case, the tire is 4. The next digit represents the wheel size the tire will fit. This tire is meant for trailer wheels that are 8 inches in diameter.Trailer tire sizes are broken into main groups 12 inch and smaller and 13 inch and larger. Sizes 12 inch and smaller are generally listed by a two number size, such as 4. The first number in this size is the width of the tread, the second number is the size of the rim that it mounts on.
Are trailer tires stronger than regular tires?
Car tires simply aren’t built to handle trailer-specific stresses. The thinner sidewalls cannot support heavy trailer loads or resist swaying forces effectively. Load ratings on car tires are calculated for vehicle frames, not trailer frames, which distribute weight differently. 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.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.D tires are typically rated for a higher load capacity, making them ideal for heavy-duty trailers that carry substantial weight. On the other hand, R tires are generally designed for lighter loads and provide a smoother ride, which can be beneficial for recreational trailers.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.
What is the difference between 205 75R15 and 225 trailer tires?
The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27. The 225 has higher capacities available for it as well. That 20 mm difference affects how much rubber touches the road: A wider tire (225) usually gives you more grip and better cornering stability. A narrower tire (205) typically rolls more easily, which can boost fuel efficiency and deliver a slightly softer ride.
