Abstract
The paper presents the results of a laboratory investigation on the variation of the tyre sliding grip coefficient depending on the tyre construction, the air pressure, the vertical load and the wheel camber. Eight different models of tyres are tested. A significant reduction of the tyre sliding grip coefficient on a hard ground was registered, when the tyre pressure is low and the wheel camber is bigger. The analysis of results and explanation of causes are done.
Highlights
The influence of air pressure in the tyre pand vertical load Gk on the tyre sliding grip coefficient φ has been investigated in many works [120]

Summary
The influence of air pressure in the tyre pand vertical load Gk on the tyre sliding grip coefficient φ has been investigated in many works [120]. The data for the influence of the constructive properties of the tyre on the relationship between φ, Gk and p were collected [2, 4, 15, 19]. The results show that tyre sliding grip coefficient and its variation depend on the tyre load, the air pressure in the tyre and the wheel camber. In this article the influence of the vertical load, the tyre pressure and the wheel camber on the sliding grip coefficient of the tyre is investigated. The results concern a dry horizontal road and were obtained for different constructions of tyres with different wear
