Loss of braking power and rubber skidding on a wet road is still an open physics problem, as neither the hydrodynamic effects nor the loss of surface adhesion that are sometimes blamed really manage to explain the 20–30% observed loss of low-speed tyre–road friction. Here we report a novel mechanism based on sealing of water-filled substrate pools by the rubber. The sealed-in water effectively smoothens the substrate, thus reducing the viscoelastic dissipation in bulk rubber induced by surface… 
Rubber friction on wet and dry road surfaces: The sealing effect
Rubber friction on wet rough substrates at low velocities is typically 20%‐30% smaller than for the corresponding dry surfaces. We show that this cannot be due to hydrodynamics and propose an

The influence of the local heating on the rubber friction is studied, and it is shown that in a typical case the temperature increase results in a decrease in rubber friction with increasing sliding velocity for v>0.01 m s(-1).
Physical Model of Tire-Road Contact Under Wet Conditions
A physical model to describe the contact between rubber and a rough surface with water as intermediate medium is presented. The Navier–Stokes equations are simplified and surface properties are
Model for the Pattern-Dependent Wet Grip Prediction of Tires
A new approach to the description of the wet-braking behavior of passenger car tires was thus demonstrated, which can be extended to more complex tread geometries in the future.
Experimental study on wet skid resistance at different water-film thicknesses
Purpose Driving safety on a wet road is closely related to the wet skid resistance of tires. The purpose of this paper is to reveal the evolution of wet skid resistance at different water film
Road Surface Measurement and Multi-Scale Modeling of Rubber Road Contact and Adhesion
A major challenge in tire, as well as in road engineering, is to understand the intricate mechanisms of friction. Pavement texture is a feature of the road surface that determines most tire-road
Anti-sliding Risk Model of Wet Surface for Asphalt Pavement and Test Verification
A layer of water film will form on the road surface in rainy weather. Due to the lubrication effect of water film, the anti-skid ability of driving vehicles decreases, which will lead to road traffic
Rubber friction on (apparently) smooth lubricated surfaces
We study rubber sliding friction on hard lubricated surfaces. We show that even if the hard surface appears smooth to the naked eye, it may exhibit short-wavelength roughness, which may make the


On the theory of rubber friction
Rubber Friction on Self-Affine Road Tracks
Abstract A basic theoretical concept of rubber friction on rough surfaces is presented that relates the frictional force to the dissipated energy of the rubber during sliding stochastic excitations
Theory of rubber friction and contact mechanics
When rubber slides on a hard, rough substrate, the surface asperities of the substrate exert oscillating forces on the rubber surface leading to energy “dissipation” via the internal friction of the
The physics of tire traction : theory and experiment
This book, containing the papers, panel discussion and general discussions from a symposium held in October 1973, treats the many different phenomena that occur when traction demands are made upon a

An important result is that even when the surface roughness is so high that no adhesion can be detected in a pull-off experiment, the area of real contact may still be several times larger than when the adhesion is neglected.
Dewetting of a water film between a solid and a rubber
A water film (thickness e) between two hydrophobic solids is metastable. If contact is established (over an initial disc of radius R(0)>R*, where R* is a certain nucleation size), the dry path
Contact area between a viscoelastic solid and a hard, randomly rough, substrate.
Using a recently developed contact mechanics theory, the time-dependent contact area as a viscoelastic solid is squeezed against a randomly rough substrate is studied.
