Glenn,finally tried the 225/45-16 combination.Got some sp8000's at a good price.They fit without a peep.Even with the H&R springs. "NO LIP ROLLING REQUIRED". Returning the bat to sporting goods in the am. Thanks for the advice,you where right on.The 225/50's won't go to waste.My wife insists that I bought the S-4 because I didn't know what to do with the tires I took off.Very Intuitive, that woman.
