Should I need an alignment after putting on new wheels? Ever since the new wheels it seams by gas is being eating faster, and my steering wheel wobbles after I apply the brakes. I went from ws6 wheels to Z06 wheels that are wider. Can anyone help? thanks

 

how was your alignment before the change? if it was fine then you shouldnt need one, i would double check that you didnt over tighten the lugnuts

 

Alignment shouldn't be an issue.

Gas going down faster, can be due to heavier wheels and or tires, thus more rotational mass for the engine to move.

The wheel wobbling when applying brakes is the rotors are warped. You might have over tightened the lugs.

 

My Nitto 555's(on stock ws6 rims) wore on the outer shoulder faster on the front. Is this from alignment or just wide tires? I'm putting on new wheels(8.5X19 + 9.5X19) and nittos soon and wondering if it will need alignment.

 

its an alignment issue for sure if your wearing on one side faster than the other

 

Yes you have an alignment issue, get it fixed before you eat up another set of tires.

 

Yea if its wearing out the outer shoulder thats a sign of to much postive camber.

 

Wider and sticker tires make fuel economy worse. For the wobbles, it sounds like you didn't tighten down the front wheels in a cross pattern making your rotor seat unevenly.

 

If your car has too much "toe-in", you'll wear the outside edge faster.
Too much "toe-out, and you'll wear the inside edge faster.

The camber might be a factor , but most likely it's too much "toe-in".

 

I'd definitely have that checked out.

 

You are right to a degree. Toe does play a big factor in wearing out the edges. If it is toe you will usually get a feathered edge to the tread on the tires also. You need an alignment though. Wheels shouldn't change the alignment one bit.
