In this comparison, we are comparing a tyre from a manufacturer from Taiwan (Nankang) against a tyre from a manufacturer from Singapore (Giti). Giti is a brand that belongs to the GT group. Generally, Giti summer tyres are slightly better rated (44%) than Nankang (41%). But when it comes to comparing Nankang Sportnex AS-2+ and Giti Sport S1, the rating is the same - 0%. The first tyre test of Nankang Sportnex AS-2+ was done in 2016, compared to 2018 when was the Giti Sport S1 first tested. Important for this comparison is also the Automotorsport 2018 225/45 R17 test, where both the Sportnex AS-2+ and the Sport S1 were tested.
