help me pick a tire size for the rear!

[polo12345]

ok well just looking for the best tire size for my rear wheels. here is a pic of my current setup...It's 18x9 with a 22et. currently the tires on it right now are 245/40/18 but I want to switch it to either 225/40/18 or 215/40/18 but having a hard time picking. In terms of looks it should look pretty similar right? the 225 is actually cheaper then the 215's but I want to buy the tire size that will look and fit best with my car. here is the pic

Whats wrong with the 245?

I think he's rubbing with the 245's, seeing he has a 9" wheel with +22mm offset and is lowered

I can't believe that it works, I just had almost the same setup with a et35 offset and it rubbed bad. I'm now going to 245/35/18's

hey guys thanks for looking at the thread i'm gonna be going with 225/40/18 for the rear. I was thinking the 215 will be just wayy to thin for the rear especially since I want to be as flush as possible. But yeah the 245/40/18 actually worked out with my setup but it just looked odd since the rear tires are sooo much bigger then the fronts. Just going for the perfect look.
