its the offset most people use the 35 offset and they dont stick out as much in the front.
Check the stamp on the inside of the wheel and make sure they didn't give you 24mm offset.
Whats the tire size? Camber? Lowered? I'm thinking they might have sent you +24's as well, although I wouldn't be surprised if the tire was just a beefier 245. All tires are not created equal.
Edit: hmmmm
those are +24 cobras.![]()

More camber.
I have pictures of a GP with +30 saleens, once lowered with a bit camber itll look fine but youll need to roll the fenders.
as you can see his 245/45/18 look a little more stretched than yours. to be fair i run -2.0 camber since i lowered, left it alone. My bald ass tires did chew through the side but they were already done otherwise so don't worry much. that said i did run them for 2 years without getting an alignment so my toe could be way off.
edit: just jack the car and take one wheel off, see the offset stamp. itll take you 10 minutes.
you don't just burn up tires so long as your alignment is right. you can run up to -2* or so and be perfectly fine. in fact, that's only a 0.5-1.0* more than "stock spec".
being afraid of an aggressive alignment is laughable. don't be the guy to shoot down good ideas just because you're uneducated about them.
and theoretically when you lower it you'll introduce more negative camber naturally. so best get over not wanting to run more than stock camber.
