I know a guy selling a set of squared Antera #309's 18x8, et+45, backspacing 6.4, bore 63.4, brand new tires yokohama yk580 245/40/r18. I'm not lowered yet, but just waiting on the new struts for a set of sportline lowering springs. He is willing to sell them to me for 400.00 for the set. Its a great price even for just the tires, but should i even waste my time trying to get them to tuck, or not rub under full lock?[???]

Are they 5x108? If not then short of using hub bolt adapters it won't fit.

http://www.antera.com/pdf/ford.pdf These are the only antera wheels that would fit the Focus from the current range.

Holy crap, that is a lot of numbers. Visuals always help me.

Here is thee best wheel and tire calculator I have ever seen... http://www.rimsntires.com/specspro.jsp

Plug in your current wheel info and then the other wheel info. At the bottom it will have recommendations of car modifications and differences in speed.

Awesome wheel calculator..
