Uniroyal Rain Expert 3 205/60 R15 91H

A distinctive feature of the Uniroyal Rain Expert 3 summer tire is that it was developed by a North American manufacturer for the European market. Like the models of the two previous generations, it is characterized by improved traction properties on wet pavement. To achieve this, more than original technical solutions were widely used, which will be discussed below.

SST Technology

The name of the SST technology is an abbreviation composed of the first letters of the words Shark Skin Technology. Its essence lies in the use of the ability of shark skin to reduce hydrodynamic resistance. Elements similar to it are located on the bottom and side walls of the drainage grooves, which has significantly increased their throughput and, along with it, resistance to aquaplaning.

Reliability in turns

The tread pattern of the tire combines the advantages of asymmetric and directional design, since it uses characteristic solutions for them. One of them is the enlarged blocks in the outer shoulder zone. In addition to their massive size, these tread elements are distinguished by their transverse arrangement and trapezoidal shape in the side projection. All this gives the blocks exceptional resistance to lateral acceleration forces, which, in addition to improving traction in turns, provides the driver with very clear feedback. This makes the control process much easier, especially in complex situations.

Long service life

The tire is characterized by a long service life. To a large extent, this is ensured by the tread design. The elements that form it, in addition to other operational properties, provide a uniform distribution of external load, which reduces the risk of premature wear.

Key features of Uniroyal Rain Expert 3

- SST technology significantly reduces the risk of aquaplaning;
- reliable and predictable behavior when maneuvering, thanks to wide and rigid shoulder blocks on the outside of the tread;
- long service life due to optimized distribution of external pressure on the contact patch.
