All-season tire

Passenger - All-season tire

365 DAYS Plus

High-safety driving and comfort in all weather conditions

The SYRON 365 DAYS Plus is a reliable companion for any season in mild climate regions.

The modern design includes arranged V-shaped grooves and a modern structure profile, which provides a high-safety driving and comfort in every weather conditions.

With its dynamic appearance the SYRON 365 DAYS Plus will take you to your destination safely.



  • The effective position of the sipes in different directions increases the traction on ice and snow
  • Sipes in the middle tread area provide the necessary traction on winter conditions
  • Stable shoulders: increase driving stability and durability of the tires
  • V-shaped grooves: for improved water drainage and grip on wet roads
  • Tread wear composed of a mixture of silica: for a better wet grip and rolling resistance
  • Cooling Eyes provide the shoulders for cooling in summer and in winter for increased traction due to “snow-snow contact”

GTT – Green Tire Technology
We care about our environment throughout the manufacturing process and throughout the life of the Syron tires. The new technologies allow minimizing the harmful effects of the tires on the environment and achieving more durability and longevity at the same time. All Syron tires are manufactured according to EU guidelines without HA oils, low-emission and ecological materials.

cetCET – Cooling Eye Technology
A tread structure specially developed for Ultra High Performance tires, which provides a better heat dissipation and cooling. This achieves a safer tire cover at high speed.


dtcDTC – Double Tread Casing
This is a special production technique that ensures comfort and a steady mileage. While the substructure of the tire bead is compressed by complex production procedures, the upper layer is softer and more flexible. This leads to an optimized grip, excellent steering precision and safe handling.

wdsWDS – Water Drainage Surface
The contact surface of the Syron tire has been optimized for the best possible water drainage. This tire has more projecting main and side channels with a larger volume which can absorb the water quickly when wet and also quickly deduce it. This increases the safety margins in wet roads and reduces the risk of aquaplaning.

bstBST – Block Stabilization Technology
Tread blocks are deformed during normal handling by braking and driving forces. The block Stabilization Technology provides the best possibility to keep the tread blocks constrained, without having to reduce the grip edges.

ekpEKP – Extra Kilometer Performance
With the EKP technology you can benefit from a longer durability of the tire, without loss in performance and safety. The rolling resistance of the Syron tires was significantly reduced for a higher mileage and lower fuel consumption. Therefore, the tire runs more easily and stays cooler. Thanks to the EKP Syron Performance, the tire lasts much longer.

sttSTT – Silence Tread Technology
The Silent Tread Technology is used for the design of the Syron tires tread. The optimized tread patterns enhance the driving experience with reduced noise and less vibration transmission. The tires are thus more comfortable, because you can neither hear nor feel them.

ictICT-Intelligent Compound Technology
SYRON Intelligent Compound Technology allows you to adjust the tire to different weather conditions during the year. By using a silica Acid Additive suitable for the whole year, the tire guarantees a balanced performance in all weather conditions.

fstFST – Fuel Saver Tire
Using Syron Fuel Saver Tire technology reduces the amount of power which is lost by rolling friction. During production we use lighter materials to reduce the weight of the tire. This allows a higher mileage and low fuel consumption.
