RubberMaster H187 ST 165/80D13 A78-13 C 6 Ply 5 on 4.5 Modular Assembly
The RubberMaster H187 is a highway terrain, all season tire made for trailers. This model should not be mounted on light trucks. The ribbed tread design and the all season compound offer exceptional dry, wet, and winter road grip. At the same time, wide grooves prevent hydroplaning in wet situations. The ribbed tread pattern manages to keep road contact all the time, which boosts steering responsiveness and driving stability. The stronger construction and rubber compound increase load and driving durability. The RubberMaster H187 enables the tire to carry and withstand heavy loads.

This is a bias ply or diagonal tire. Due to the tire's internal construction and size, it is possible that the tire will look deformed. Smaller diagonal tires do not have reinforced constructions that can keep the tire from deforming. The bias construction and the small tire's non-reinforced internal structure allow the tire to fold in when it is deflated or not properly inflated. This is not constructional damage or an issue; it is a normal occurrence with such tires. In such cases, the tire needs to be mounted and inflated to the proper PSI or, in some instances, an inner tube needs to be added. The proper PSI and the inner tube are able to maintain the tire's ideal shape, preventing the bias plies from looking deformed. This ensures their performing safety and durability.
The photo is a representation of the tire's possible deformation, it does not represent the specific tire model, size, tread pattern and application.


Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
