Naphthenic tire oils were used in winter tire tread compounding. Properties of compounds were compared with similar compounds made of other safe tire oils. Retreaded passenger car winter tires were prepared using the compounds. Traction and rolling resistance of the tires were determined in different weather conditions.It was shown that naphthenic oils may lead to improvement of winter traction and rolling resistance without compromising other tire properties.
