In this comparison, we are comparing a tyre from a manufacturer from Great Britain (Avon) against a tyre from a manufacturer from Holland (Vredestein). Avon is a brand that belongs to the Cooper group. Generally, Vredestein summer tyres are slightly better rated (55%) than Avon (24%). But when it comes to comparing Avon ZZ5 and Vredestein Ultrac Vorti, the rating is the same - 0%. The first tyre test of Avon ZZ5 was done in 2020, compared to 2016 when was the Vredestein Ultrac Vorti first tested. Important for this comparison is also the Autobild 2020 245/45 R18 test, where both the ZZ5 and the Ultrac Vorti were tested.
