Can i use 245/45/17 tires
On a 2004 with sport package and aftermarket rims?
I think my rims have more offset than stock but not much more.
A great deal on these snow tires

 

I dont think so, the diameter will be out by too much: its recommended to stay within 3% but it may affect 4 wheel drive or DSC if fitted?
