MRF Steel Muscle S1R4 Tires

The MRF Steel Muscle S1R4 is a highway terrain, all season tire made for commercial vehicles. This model was manufactured for the vehicle's steer axle.

This tire model was manufactured by one of India's leading tire manufacturing brands, the Madras Rubber Factory. This company uses state-of-the-art tire manufacturing technologies and methods, which creates high quality products of the tire market. MRF is the leader of the original equipment and replacement tire industry in India as they aim for constant progress and improvement.

The tire improves the tread life length. The flat footprint and the durable compound work together to boost usability by ensuring a slower and even wear manner. The compound features wear-resistant rubber materials, which decrease the tread wear rate. The tread's flat footprint guarantees even pressure circulation along the tread area, avoiding irregular wear formations. This combination enables the tire's elongated service life.

The model helps improve year-round traction. The symmetric ribbed tread design and the all season compound increase the dry, wet and winter weather grip on the road surface. The tread elements, with the siping placement, boost the surface traction with extra biting edges. The compound elements optimize the rubber flexibility in versatile temperatures. The circumferential grooves prevent hydroplaning by dispersing water and slush from the footprint, increasing the wet weather performing safety.

The Steel Muscle S1R4 upgrades controllability as well. The tread's ribbed pattern allows the tire to maintain the surface contact at all times, which boosts steering responsiveness and driving stability. As a result, the tire ensures the tire's steering response time and accuracy, while the structure is secured against the driving pressure affecting the tire. The strengthened internal structure upgrades the load capacity, as the tire does not deform under load and driving pressure. This guarantees the driver's constant control over the vehicle, promoting a safer performance.

There might be discrepancies of sizes between brands and models of tires which have this size formatting. As the manufacturers only provide the tire width and the rim diameter with these tires, various brands and models will have size differences. In order to ensure the correct size is purchased, the overall tire diameter that is needed should be checked.

This is a Tubed Type Tire (TT), which requires an inner tube to properly function. This purchase does not include the inner tube or flaps.

The Overall Diameter or O.D. advertised represents the tire's overall diameter in inches, once the tire has been properly inflated and mounted per the manufacturer's recommendation. This advertised number is provided to TireMart.com by the tire manufacturer.

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.
