Right now I have Falken tire. 245-40-18 in the front, 275-35-18 in the back. When I get new tires very, very soon, I'm getting 285-40-18 in the back. (Nitto 555 Ex. for 191$ a piece) And In the front I'm gunna get 255's because my tires in the front right now look like there almost too small for the rim. It's like, the opposite of what it looks like when you have shoulder roll. What would be a good tire size for the front... I don't want anymore than 255's though... And I need a size nitto has.. 255-40-18 or 255-45-18 and 285-40 in the back.
