How Can You Find the Tire Load Range for E1 Tires?

All tires, including those with the E1 designation, have load range and maximum inflation numbers labeled on their sidewalls. The load range identifies how much load a tire can take at specific pressures.

While most passenger vehicles have standard load ranges, light trucks use a system in which letters A to N identify the strength of each tire. Letters farther along the alphabet identify stronger tires that can withstand higher inflation pressures and carry heavier loads. E1 tires have a 10-ply load carrying capacity. This doesn’t mean the tire is actually built with 10 plies, but rather that it contains one or two plies of equivalent strength.
