Is there a difference between load range or ply being a letter vs a number?
They are very similar. Ply used to refer to the actual number of plies the tire was built with. Tires today don't need as many plies because of modern material improvements are usually given a Load Range instead, represented by a letter. Each letter is equivalent to 2 plies. See the chart below to help guide you:
Load Range B equivalent to 4 Ply rating
Load Range C equivalent to 6 Ply rating
Load Range D equivalent to 8 Ply rating
Load Range E equivalent to 10 Ply rating
Load Range F equivalent to 12 Ply rating
Load Range G equivalent to 14 Ply rating
What do the letters before the tire size stand for? (I.e. ST205/75R15)
ST: Special Trailer
P: Passenger Vehicles (cars, vans, light-duty trucks, and SUVs)
T: Temporary Spare
C: Commercial (vans or delivery trucks - capable of hauling heavy loads)
LT: Light Truck
