Nov 2, 2023 · To determine the minimum load capacity each trailer tire should have, divide the trailer’s GVWR (Gross Vehicle Weight Rating) by the number of trailer tires. Then, add a safety margin to account for potential weight distribution discrepancies and dynamic forces, increase this calculated load capacity by 15% to determine the ideal load capacity for each tire.
Here at Treadworld, to be sure we have all the bases covered, we describe how much our trailer tires can carry at the optimal PSI as the “Ply Rating/Load Range” which will show up as a letter/number such as 14/G—which corresponds to a load capacity equivalent to 14 plies and a load range of “G”—which equals a capacity of single/dual ...
If a trailer were to have, for example, two 3500-lb-rated axles, then it would likely have a gross weight rating (GVWR) of about 7000-lbs. In this example it would be appropriate to use 4 tires rated for Load Range D, such as # TA24VR. This wheel/tire combination is rated for 2540-lbs at its specified 65-psi pressure.
Feb 3, 2024 · Each load range corresponds to a specific weight capacity and required tire pressure, making it essential to match your trailer's requirements with the appropriate tire load range. Overlooking this crucial aspect can lead to increased tire wear, reduced fuel efficiency, and even pose significant safety risks.

The wheel/tire you referenced, Kenda 4.80-12 Bias Trailer Tire/Wheel # AM30660, combines a steel wheel rated for 1250-lbs with a Load Range C tire that itself is rated for 990-lbs at 90-psi. Since the tire is rated lower than the wheel, the lower rating determines the overall capacity of this item, 990-lbs. expert reply by: Adam R.

Apr 3, 2023 · The most important number to lookout for when it comes to understanding a tire’s load-bearing capacity is its Load Index (LI). This number can range from 0 to 279 and indicates a maximum permissible weight in pounds (lbs) that must not be exceeded. Different trailer tire models have different LI values and these are expressed in terms of both ...
