Influence of rubber compound and tread pattern of retreaded tyres on vehicle active safety.
The aim of the article is to present the results of road tests of original and retreaded tyres, analysed in the aspect of vehicle active safety. The tests covered emergency braking, steady-state circular tests and severe lane-change manoeuvre. The tests were performed in summer and winter conditions. Original Michelin tyres and Michelin tyres retreaded with summer and winter rubber compounds were used. The results of the tests proved that vehicle active safety is affected by retreaded tyres. The differences between braking deceleration of a car with original tyres and braking deceleration of a car with retreaded tyres confirmed the necessity of performing braking tests on the place of accident with the set of tyres with which the vehicle participating in the accident was equipped.
