I just added a set of Goodyear Eagle RSA's 295-40-20's on a set of Replica Alloys that are 20x10. They are on their web site under the Charger section and do a great job of matching the IE wheels. No way are you going to get more tire on the rear without rubbing. I'll post pics as soon as my wife takes them (I'm not allowed to touch her camera). Hoping this will help with traction. Next I'm going to fix my seats. They are actually getting better as I sit in them more. I guess that is one of the few benefits of having a big A$$.
