i have a g37 coupe keep getting wear on my left front tire had new tires installed and aligned after 3 weeks left front tires started making noise again veh has never been wrecked had suspension looked at found no problem love the car but it is anoying and *** you all know 19"s are are not cheap any feedback would be appreciated thanks
mikeg its all stock the only thing i added was a sub

 

are you dropped? it could be the toe and caster messed up. where is the wear on the tire?

 

wear is on left front tire ive never even rubbed a curb also i work at a toyota dealer in the service checked alignment again still good (lost)

 

i know its on the left tire but is it in the inside where its wearing or outside, middle or the whole tire gets bald? Is it also a smooth wear or rough?

 

smooth wear would be camber issue and rough would be toe and caster.

 

its on the inside and its getting cupping making a whooping noise

 

Sounds like an alignment issue to me.
