LLD37E +
In this review, we will talk about high quality and, mind you, inexpensive tires designed for driving wheels of commercial vehicles. So, Leao LLD37E +. What is this rubber, what is it good for, and are there any drawbacks that should be paid special attention to?
Who produces
LLD37E + tires are independently developed by Shandong Leao March Tire Co., Ltd. The company has been producing this tire model since 2017. The company, today, is one of the five largest car tire manufacturers in China and the twenty largest world manufacturers.
Leao Tire and its manufacturing facilities are located in China and Taiwan. Tire production is automated as much as possible. This was done to exclude the possibility of a negative impact of the notorious human factor on the quality of finished products. For the same reason, the company has implemented a multi-stage quality control. As a result, there are no complaints about factory defects during the operation of this tire model.
It should be noted that not so long ago the Leao Tire brand was popular and in-demand exclusively in Asian countries. The company introduces its products to the western market in 2010. To attract a western buyer to its tires, the manufacturer sells them at very attractive prices, although the quality level is very high.
But back to the LLD37E + model.

Design features
As already mentioned, Leao LLD37E + tires are designed to be mounted on drive wheels. That is, these tires, for obvious reasons, undergo the greatest stress. Therefore, the design of such tires has been developed taking into account maximum resistance to mechanical damage and, first of all, to abrasion.
The tire tread is made using an extra-strong rubber compound. This is a special thermosetting rubber that does not melt in the heat and does not tan in winter. In addition, this rubber provides acceptable traction, even though the tread does not wear off as quickly as the tread of most other all-season tires.
An effective tread design that combines deep longitudinal grooves with diagonal grooves is responsible for providing sufficient traction. In addition, the friction of the tire with the road surface, especially in winter, is increased by sipes - there are not many of them here, but they are there.
Returning to the topic of strength, we note that the tire carcass design is radial. This is a time-tested solution that makes the tire stronger than a bias tire. Yes, such a tire, due to the denser arrangement of the threads in the frame, turns out to be heavier, but this is not too much of a problem when it comes to equipping trucks. But due to the radial structure of the carcass, in addition to high strength, the tires are perfectly balanced, which is also a significant advantage, which we will discuss below.
Fuel economy is real
Tires can reduce fuel consumption. Don't believe me? In this case, install Leao LLD37E + along with steering tires from the same manufacturer, and you will see that fuel consumption will decrease by 15-20% on average compared to normal consumption.
Fuel economy is ensured by well-balanced tires and, as a result, minimal rolling resistance. Well, since nothing interferes with the rotation of the wheels, less fuel is needed. Think 15% is a negligible saving? Try to subtract these percentages from the amount of fuel consumed on long-haul haulage, and you will realize that the savings are significant.
And in winter and summer and even in the off-season
It is believed that an all-season tire does not drive well at any time of the year, since in the heat the rubber melts, and in winter it becomes stone, which negatively affects driving performance. Perhaps this is true, but not in the case of Leao LLD37E +.
These tires are truly all-season and they are, first of all, made like that by the thermosetting compound, from which the tread is molded.
A thermosetting compound is a rubber compound that retains average properties at both high and low temperatures. As a result, these tires, regardless of climatic conditions, provide a good grip on the road surface. Moreover, for the same reason, these tires have a long service life, since they do not wear out in the summer.
I am more than expected, and in winter they do not crack due to increased rigidity.
However, the all-season operation becomes possible not only because of the material from which the tread is made but also because of the effective tread pattern. A sophisticated system of longitudinal channels and diagonal sipes provides good grip not only on dry asphalt but even on snow, both on loose and rolled. More importantly, these tires provide excellent traction. The effective tread pattern intensively removes water from the contact patch. As a result - no slippage in winter when driving uphill and, of course, less braking distance!
Versatility of application
While most of the tires for long-haul trucks are used only on good asphalt, the Leao LLD37E + allows you to move off the asphalt onto a dirt road. Such versatility of application, on the one hand, is explained by the increased tread height. On the other hand, versatility is due to the tire design and manufacturing materials.
Unlike conventional trunk tires, Leao LLD37E + are less prone to cuts or punctures when hitting sharp rocks or when hitting obstacles such as curbs, speed bumps, etc.
Attention: For more efficient operation outside asphalt roads, Leao LLD37E + is equipped with a self-cleaning function.
That is, when the wheel rotates, stones fly out of the tread grooves. The advantage is obvious, as the tread gradually deteriorates due to stones. This is especially important for tubeless tires. If there are no stones stuck in the tread, the tire will last much longer!
The longevity you dreamed of
The resource of all-season tires, one way or another, is less than the resource of ordinary tires intended for seasonal use. But with Leao LLD37E +, everything is completely different. These tires are durable, which, as already mentioned, is ensured by the design features and the selection of production materials.
To make it clear how reliable these tires are, we note that Leao Tire gives them a guarantee for up to 5 years or more than 80 thousand km. mileage. This is a very good guarantee for all-season truck tires.
Let's summarize
So, we talked about the Leao LLD37E + tires. These are high-quality and inexpensive tires that will surely improve the driving performance of your vehicle. Do we recommend buying these tires? Of course, we recommend, especially since the price is great if you buy these tires from an authorized dealer. We are confident that the Leao LLD37E + will be an excellent choice for practical buyers who know how to count money but do not intend to sacrifice the quality of the tires they buy.
