What is Dual Marked Tires
Some tires have been developed for more than one application, which means, for instance, that the tire can be used on a Loader application (Loader and Dozer operation – indicated by the TRA code L on the sidewall) as well as an Articulated Dump Truck application (Earthmover or transport operation indicated by the TRA code E on the sidewall).
These tires are often called ‘dual marked tires’ or ‘tires with dual specification codes’.
The example above shows a dual marked tire 875/65R29 E3/L3.
TRA Code L3 corresponds Load Index 214 (21200kgs) and Speed Symbol A2 (10 km/h)
TRA Code E3 corresponds Load Index 203 (15500kg) and the Speed Symbol B (50 km/h)
In this example the dual marked tire has for both applications (Loader and Earthmover).

* Multiple Star Rating
Radial Tires are sometimes marked with “LOADER & DOZER ★(one star)” and “EARTHMOVER ★★(two star)”, which have specified load capacity on each servicing condition.
