Sicuro Secure M93 315/80 R22,5 158/156J

In the segment of heavy commercial vehicles, the leading axle is the most demanding consumer of tire resources. Here, not only traction force is important, but also fuel efficiency, even wear, and predictability on a wet road. The Sicuro Secure M93 model is designed specifically for these tasks. A commercial tire for heavy trucks that combines aggressive traction on the leading axle and low rolling resistance.

Tread and its design

The pattern is made according to a block scheme with a high density of elements. In cross-section, we see three ribs formed by identical block structures. The dense arrangement of elements increases the contact area with the road, which reduces pressure on the unit surface and slows down abrasive wear.

Z-shaped notches

Each block is equipped with a Z-shaped groove. This provides:

- additional gripping edges - the edges work like micro-grips, providing reliable traction on wet asphalt;
- preservation of block stiffness - unlike straight cuts, the Z-shaped form does not reduce the modulus of elasticity of the element;
At the same time, rolling resistance remains at the level characteristic of fuel-saving models.

Self-cleaning

The developed network of channels between the blocks evacuates water and dirt. When driving on a wet road, the liquid is instantly squeezed into the longitudinal and transverse grooves. This maintains traction on the leading axle even in difficult weather conditions.

Formula for even wear

One of the common problems of leading axle tires is the "saw-tooth" wear of the blocks due to uneven pressure distribution. In this model, this problem is solved at the level of geometry. The wide contact patch increases the interaction zone with the road, reducing local overloads. The optimized tread profile provides even intra-tire pressure across the entire width of the tread. This means that the central and shoulder zones wear out synchronously, extending the overall mileage.

Key features of Sicuro Secure M93:

- applicability - leading axle of heavy trucks;
- dense arrangement of elements for even pressure distribution and reduced wear;
- special grooves on each block - additional gripping edges without loss of stiffness and increased rolling resistance;
- developed system of inter-block channels - effective self-cleaning from dirt and water diversion to protect against planing;
- increased resource - wide contact patch and even pressure distribution minimize wear.
