I have almost always bought on a tire, except once on web tires. On rubber, the price is higher but serious and recent product (manufactured within the current year) made them the best choice, but this time in November 2019 I bought winter tires a year before (46/18). I turn to them for quality, but if I buy products I can find from other retailers at a lower price do not understand why I have to stay true to GOMMADIRETTO.
Thanks and best regards
