Another silly question. Should I be focusing on load range rating only or should I look at Max Load rating? For example my current Pirelli rated for 2403 lbs max load. Goodrich All-Terrain TA KO2 are 2680 lbs and Nitto Terra Grappler are 2833.
I’m not looking to increase my towing capacity instead I’m after more stable and safest ride while towing.
Generally speaking for truck tires the following is true (p rated tires especially vary by load index):
Max load is determined by a function of the tire size and the tires inflation pressure. Load is always stated @ a certain inflation pressure. A tire designed to carry more weight will be constucted to handle a higher inflation pressure or be a larger tire. Load range or ply rating are synomous terms. The load range tells you only part of the story. Tires with a D range are designed for 60 psi....E range - 80 psi .....G rated tires have a 100 psi max inflation value.
