Guys,
Is silverstone tyres still have very loud noise compare to Other brands? Last time
Silverstone tyres are famos of this. But one thing good is there can last very long, cause the rubber is harder. Itu sebab banyak teksi use this brand.

mmm are u sure? I just confusing with the GDI engine that allows air-fuel ratio to 65:1 compared to multipoint injection maybe around 14:1.

However, 65:1 is really saving rite? but not to hardcore driver who throttle lot. Because, in hard acceleration, the ecu set the injector as usual. i mean air to fuel ratio 14:1 approximately.
