Hi,
I own 2K lancer, it's 1.6L 16V I replaced the stock wheels which were 14" with 17" rims.. In the begining I install NANKANG tires 215/40 17, but I faaces alot of vibration, they tried to fix it but at last they told I have to change them.. So I replaced them with TOYO 215/40ZR17 (Proxes FZ4).. but I'm stiil facing this vibration.. They still having warranty & I'm going tomorrow to check with the dealer once again..
So can some one till me why this happening to my car..? Did I made a mistake to replace my rims with 17's

 

The thinner tires you have on your new wheels will be transmitting more road "feel" to the cabin and you'll get more feedback from the car that way. If it's more than just that it may be that the lugnuts were threaded on wrong when the wheels were installed .

 

Thank you pjal84

you're right, the lugnuts might be the reason..

I'll check it.. any way I'm going now to the dealer..
Thanks again.
