What is the ply rating on tires?

LT-metric, LT-flotation and LT-numeric tires are branded with their load range (load range E or LRE) or their ply rating (10 ply rated) on their sidewalls and list their appropriate load range letter in their descriptions as LT245/75R-16 E, 7.50R-15 D or 31×10.50R-15 C.

In this manner, what does tire ply rating mean?

A tire ply rating is an expression of the tire’s strength and capacity. The days of cotton layers or plies forming the internal construction of tires are long gone, so the ply rating no longer has a direct connection to a tire’s construction and number of layers.

What is the difference in ply for tires?

The ply rating is how many layers of rubber is on the tyre. A common one is 8 ply meaning it has 8 layers of rubber. For example, regular car and light tyres have 4 plies under the tread and only 2 on the sidewalls, hence a 4+2 ply tyre. Often there are more plies under the tread area of the tire than the sidewall.

What does SL ply rating mean on tires?

Reading Tire Load Info. Most alphanumeric tires feature a load range of B, which indicates that they are restricted to the load that can be carried at a maximum inflation pressure of 32 psi. C, D, or E tires are capable of greater loads. Most load range C, D, and E tires are intended for light-truck applications.

What ply is SL?

Expert Reply: Load range D has a capacity of 1,220 lbs at 65 psi, whereas load range E has a capacity of 1,520 lbs at 80 psi. Basically the only difference between the two is the weight capacity.

What is W speed rating?

While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire’s 168 mph, 270 km/h maximum speed.
