OTR Grassmaster

FEATURES AND BENEFITS

  • Enhanced controllability
  • Longer lasting tread life
  • Increased traction

OVERVIEW

The OTR Grassmaster is an all season tire manufactured for lawn mowers and other garden equipment vehicles.

The model offers great controllability. The tire's optimal footprint improves its contact with the terrain surface at all times. The S-shaped tread blocks increase the tire's gripping ability, which ensures constant terrain contact. The better terrain contact boosts the steering responsiveness and driving stability. As a result, the tire has a faster and more precise response to the driver's steering instructions, while the structure is stabilized against the driving pressure affecting the model. The better maneuvering and control over the tires ensure a secure performance.

The tire's flat footprint, with the special S-shaped tread design, improves the model's traction. It increases the grip throughout the year and on soft terrain surface conditions. In this manner, the tire enhances its performing capability. The optimized tread block placement ensures a smooth traction, which does not damage the turf. The tire is capable of performing without harming the turf and grass field while the tires are in motion, making it perfect for lawn mower applications.

The Grassmaster promotes a longer tread life. The durable tire compound and even pressure distribution work together to lengthen the tread life and usability. The compound is wear-resistant, which slows the tread wear rate down significantly. The flat footprint manages to equally spread the forces of acceleration, cornering and braking out across the tread area. This actively resists the uneven tread wear, extending the tire's service life.

This is a bias ply tire. Due to the tire's internal construction and size, it is possible that the tire will look deformed. Smaller bias ply 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.

This specific tire model features a BIASED ply construction.

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.
