7^th/7

Austone Athena SP-303, trots att det var ett attraktivt pris för ungefär en tredjedel av premiumkonkurrenterna, uppvisade betydande prestandabegränsningar. Detta kinesiska budgetdäck ger dålig bromsförmåga på vått och torrt underlag med den lägsta motståndskraften mot vattenplaning av alla testade däck. Testare rapporterade att däcket tappar greppet abrupt och oförutsägbart, kräver överdriven styrinsats och producerar avsevärt buller. Trots sitt budgetvänliga pris gör dessa betydande prestandabrister det till ett tveksamt värdeerbjudande ur ett säkerhetsperspektiv.
