but wore are you tyres anyway? and its also the fact ur have a 19' dish and a wider profile hence the road noise... mine is has about 40%< thread left hence the roar... (highway speed really kills the thread quick...) the ZE suppose to have a long thread light with a rating of 400 compared to 200 for the Potenzas, so i kinda expected the road noise even if its on 15's and its a Yaris where sound deaden material are skimmed lol... Aurion wise still wearing its OEM tyres, so when the time comes i might replace it with Toyo Teo +... (since its a 16', so i guess it will be a PITA to get tyre replacement for it...)
