Tire Labeling, Ascertain the Load Capacity of Tires

LX299192-UN-18NOV16

Example of Manufacturers' Information on Sidewall of Tires

Load capacity of tires and permissible axle loads must not be exceeded under any circumstances.

Tire load capacities stated in the Operator's Manual apply for a ground speed of 40 km/h (25 mph).

Tire load capacity at a specific ground speed: On the sidewall of the tire can be seen details of its load capacity (E) at maximum permissible ground speed (F).

If the tire manufacturer has approved the same tire for another ground speed, additional information (G) is provided. In this case, note especially that tire load capacity may change in relation to the maximum permissible ground speed.

A	Tire Width ..............	Width in millimeters.
B	Tire Section ..............	Ratio of tire height to tire width.
C	Type ..............	“R” = radial, “—” = cross-ply (example: 18.4-38)
D	Rim Diameter..............	Diameter in inches.
E	Tire Load Index (LI) ..............	Maximum permissible load capacity per tire, in relation to speed index (F).
F	Speed Index ..............	Maximum permissible ground speed at which (E) applies.
G	Tire Load Index (LI) Speed Index	Tire load capacity at an alternative permitted ground speed.
Apply to your tire dealership or directly to the tire manufacturer for more information on tires and tables concerning load index and ground speed.

Speed Index	A4	A6	A8	B	C	D
km/h ..............	20	30	40	50	60	65
mph ..............	13	19	25	31	37	40

Example: Tire 540/65R38 147A8 (144/B)
• Tire Load Index (LI) ..............	147	⇛	3075 kg (6780 lb) load capacity per tire
• Speed Index ..............	A8	⇛	40 km/h (25 mph)
+
• Tire Load Index (LI) ..............	(144)	⇛	2800 kg (6175 lb) load capacity per tire
• Speed Index ..............	(B)	⇛	50 km/h (31 mph)

Permissible deviation in load capacity in relation to speed index, in percent:
Speed Index	Permissible Ground Speed		Permissible deviation in load capacity of tires at:
	km/h	mph	30 km/h (19 mph)	40 km/h (25 mph)	50 km/h (31 mph)
A6 ..............	30	19	± 0%	- 10%	—
A8..............	40	25	+ 7%	± 0%	- 9%
D..............	65	40	+ 15%	+ 9.5%	+ 5%
