General ST250 LP

General ST250 LP is a tire for truck trailers and semi-trailers. The tires are designed for long-distance and regional cargo transportation. In this review, we will tell you about the main characteristics of these tires. The purpose of this review is to give the potential buyer the opportunity to understand whether he needs these tires or not.

Choice of trailer tires

Trucks have no problem finding and purchasing truck tires. Tires for steering and driving wheels are on sale. There are summer tires for sale, there are winter tires, and there are all-season tires. As a result, the choice of truck tires is wide and varied. But how is the situation with trailer tires?

In this case, things are different, as most manufacturers go to great lengths to create quality steering, drive, and all-around tires. But the range of trailer tires is often limited to one or two models. In the meantime, choosing the right trailer tires is just as important as buying tires for the truck itself. It's no secret that a multi-ton road train slows down not only with a truck but also with a trailer.

Quality trailer tires

We present to your attention the tires General ST250 LP - they are specially made for trailers and semi-trailers, which are used for long-haul transportation. The tires are suitable for mounting on various types of trailers and semi-trailers, including box vans, flatbed trailers, tanks, trawls, etc.

Considering that the wheels of the trailer are not driving and steering, the following requirements are imposed on them:

• Maximum strength, as they have to withstand considerable loads.
• Resistant to abrasion, as when braking the trailer tires wear no less, if not more than the tires of the driving wheels.
• Increased traction for confident braking for all-season use.

All these requirements are adequately met by the General ST250 LP bus.

Advantages and disadvantages

Like all modern General Tire tires, the General ST250 LP offers a number of advantages.

• These tires are durable, it's not for nothing that the manufacturer gives them a guarantee of up to 65 thousand miles of the run.
• These tires provide increased traction on road surfaces or dense ground. As a result, the descent on sections of the road with a higher degree of slope becomes less dangerous.
• These tires withstand increased loads and are suitable for installation on most types of trailers and semi-trailers in use.
• These tires are strong enough for high-speed operation at speeds up to 360 ft/hr.
• These tires are really suitable for all-season use, as they provide increased grip on both dry and wet roads.
• These tires are inexpensive as they are sold in the mid-range segment, demonstrating the qualities of premium tires.

Are there any disadvantages? Any tires have disadvantages, but in the case of the General ST250 LP, the advantages are much greater and the disadvantages, if any, are insignificant against their background.

How and what are these tires made of?

Like all modern General Tire products, General ST250 LP tires are distinguished by progressive technologies used in production. General ST250 LP are multilayer tires, where each layer has a specific function:

• The first outer layer is the tread. It is in direct contact with the road surface, and therefore it is made as strong as possible. At the same time, this tread must provide sufficient traction with the road, and therefore the materials used to make the tread are not only durable but also elastic.
• The second layer is rubber reinforced with metal belts that reinforce the center rib of the tire.
• The third layer is rubber reinforced with a braided metal wire. This layer prevents the tire from bursting due to high pressure. Considering that the tire is tubeless, such a design feature is more than relevant.
• The fourth layer seals the inner surface of the tire and in particular the perimeter of contact with the rim. This layer is made of butyl, which, with its high elasticity, is distinguished by its high density and the absence of micropores. As a result, an inflated tire does not bleed air for a long time, maintaining consistently high pressure.

A metal cord is fused into the rubber along the perimeter of the tire to the wheel rim, which ensures uniform pressure along the entire circumference. Unlike steering or utility tires, the General ST250 LP does not have sidewall reinforcement. This is due to the fact that trailed tires, unlike steering tires, do not hit curbs and do not collapse.

With the General ST250 LP tires, the manufacturer's goal was to provide sufficient grip to guarantee heavy braking even in winter. To do this, a silica filler is added to the rubber that is used when casting a tread. Fine silica particles are denser and harder than stone and perform abrasive functions. As a result, the surface of the tread blocks, in contact with the road surface, provides optimal grip.

Tread pattern

As already mentioned, a trailed tire differs in a number of ways from driving and steering tires. And General ST250 LP is no exception since the main task of this tire is to maintain the direction given by the tractor. Therefore, the tread on the tire consists of 4 deep radial grooves. Agree that the tread is similar in appearance to the steering tires, which are also produced by General Tire. But pay attention to the fact that here the radial grooves are not perfectly flat, but are made in the form of a zigzag. This pattern, first of all, provides better traction with the road surface when braking. In addition, this shape of the grooves allows for more efficient drainage of water, preventing the effect of aquaplaning. Small lateral grooves also contribute to better grip.

The radial grooves are designed in such a way that stones and dirt do not linger in them. At speeds above 100 ft/hr, all dirt from the tread is thrown out by centrifugal force. Without contamination of the tread and without the threat of aquaplaning, the General ST250 LP tires allow you to pull the trailer confidently, without fear of being blown to the side when cornering or on a wet road.

Tire sizes

General Tire decided to limit itself to the most common tire sizes that are commonly used on American truck trailers. However, the standard is widespread, and therefore tires with standard sizes 255 / 70R22.5 will fit most trailers outside the United States. Anyway, before ordering General ST250 LP tires, compare their dimensions with the dimensions of the rims.

Buyer reviews and conclusion

Almost all buyers of all-season trailer tires note that the General ST250 LP is an excellent choice due to its durability and low price. That is, these tires, first of all, are spoken of as a practical acquisition.

In their reviews, the buyers of these tires note the high directional stability of the trailer. That is, a trailer, loaded or empty, thanks to these tires perfectly follows the tractor in a straight line and enters the turns in a straight line as if on rails. Cargo transportation is becoming more predictable, stable, and safer. Isn't that what you wanted from a mainline truck with a trailer? This can now be achieved by purchasing General ST250 LP tires.

Let's summarize

The tires are great, like everything General Tire does, and therefore a decent option for the price.
