Attention! Due to the size of the tires, Packages might be SEPARATED in the courier facility and not be DELIVERED on the SAME DAY, even though we do ship them together. Tracking information can be checked by logging on to the courier website with the master tracking number you will receive via email. For example, you can receive 3 tires in one day and the 4th one the next day or the day after, or one tire in one day and the second one day after. We understand that this is a big inconvenience for our buyers, however, this is ABSOLUTELY out of our control.

MRF Steel Muscle S1M4 Tires

The MRF Steel Muscle S1M4 is a highway terrain, all season tire manufactured for commercial vehicles. It is designed to be mounted on all axle positions.

Excellent controllability and driving stability are promoted with this tire. The ideal tread design and the durable rubber compound maintain close road contact, which increases steering responsiveness. In other words, these elements increase the steering response time to be faster and more precise to the driver's commands, while the structure is secured against driving pressure. The outer ribs and their close road contact boost cornering and maneuvering.

Year-round traction is promoted with this tire. The ideal tread design and the durable rubber compound boost the tire's grip in dry, wet, and winter weather. In this manner, the optimized tread elements closely follow the road surface at all times, while the all season compound keeps the rubber flexible in warm and cold temperatures. Hydroplaning resistance is provided as well. Circumferential grooves eliminate water and slush from the footprint in wet conditions.

The model offers a longer-lasting tread life. The ribbed tread design and the wear-resistant compound prevent irregular and premature wear formations. This tread pattern evenly distributes driving pressure along the tread area, while the special silica compound slows the treadwear rate down. This reduced and even wear lengthens the tire's service life and usability.

The MRF Steel Muscle S1M4 boosts load and driving durability. The reinforced internal structure and the rubber compound keep the ideal tire shape under load and driving pressure. As the tire does not deform under pressure it can easily carry and withstand heavy loads. This heavy-duty performance makes this model perfect for commercial applications.

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.
