In this comparison, we are comparing a tyre from a manufacturer from (Hi) against a tyre from a manufacturer from Singapore (GT). Generally, GT summer tyres are slightly better rated (37%) than Hi (18%). But when it comes to comparing Hi Fly HF 805 and GT Radial Champiro FE1, the rating is the same - 0%. The first tyre test of Hi Fly HF 805 was done in 2017, compared to 2016 when was the GT Radial Champiro FE1 first tested. Important for this comparison is also the Autobild 2017 225/50 R17 test, where both the Fly HF 805 and the Radial Champiro FE1 were tested.
