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.


AMP Terrain Attack A/T A


  • All season traction
  • All terrain traction
  • Enhanced controllability
  • Longer lasting tread life


The AMP Terrain Attack A/T A is an all terrain, all season tire manufactured for light trucks.

The tread design and all season tire compound increase the year round road gripping ability and power. The tread elements, with the siping detail, manage to increase the number of biting edges gripping the road and terrain surface during the drive, while the durable compound keeps the rubber flexibility throughout the year. Even in various temperatures the tire provides a safer driving experience with the better surface gripping ability. The tread's open shoulder detail and wide groove pattern avoid hydroplaning during the model's on-road performance. They channel water and slush from the footprint, enhancing the wet and winter weather driving safety.

The combination of the staggered tread blocks, high void ratio and detailed upper sidewall pattern also boosts the all terrain performance. They increase the tire's grip on road and terrain surfaces, allowing its secure soft, loose and uneven terrain grip. These tread elements upgrade the surface grip, while ensuring the tire's constant forward motion. The tire is able to perform in deep mud and on loose dirt as the sidewall pattern provides side-way biting edges, which prevent it from getting stuck on such terrain surfaces. The tread's high void ratio and staggered tread elements improve the self-cleaning ability. They disperse mud and snow and eject rocks stuck between the tread elements. This keeps the tire's surface contact at all times, which effectively resisting stone retention, which can shorten the tire's service life.

The durable construction enhances the tire's driving durability. The model's internal structure maintains the ideal tire shape under the load and driving pressure affecting the model. The reinforced internal structure, in this manner, significantly increases the tire's load carrying and withstanding ability and power. This upgrades the tire's load capacity. The durable structure and the tire's optimal surface contact increase the controllability. They maintain the tire's surface contact and enhance the steering responsiveness and the driving stability. The steering becomes faster and more precise in its responsiveness to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. As a result, the tire guarantees the driver's constant control over the vehicle at all times.

The Terrain Attack A/T A lengthens its usability. The stronger tire compound's wear-resistant rubber materials prevent accelerated tread wear along the tread area with the slower tread wear rate. The tread's staggered tread blocks optimize the surface contact and ensure even pressure distribution along the tread area. The decreased and even wear manner greatly extends the tire's tread and service life.

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.

The tire's sidewall also features the speed and load rating, indicating the speed and load capacity of the specific tire. The speed and load index can differ from the tires you currently have mounted on your vehicle up to a degree. Please check your vehicle's Owner's Manual or consult with your mechanic regarding the changes of your tire's speed rating and load index. If you have any questions regarding your tire size , speed rating and load index please contact us prior to purchasing and confirm with certified auto technician of any variance in speed and load index and sizes.
