Advice on changing from stock 14 inch rims and spacing

Not sure what the quote you quoted has to do with your comment, and yes I would agree that a lot of good advice has been given.

However when it comes to changing wheels and tires I really do not understand the subtle differences which I apologize if that offends you....

I'm sorry for wanting to get it right the first time regarding the look I want and fit with no rubs.
I'm sorry that I am getting as much info as possible before I spend what to me is a considerable amount of money....

I will try to understand something that I really don't, just for you

Don't apologize to these cantankerous old farts! That just makes us MORE antagonistic. ;) That's almost as bad as saying that you are planning on dropping a chebby 383 in your Duster because you heard that it fits better than a 440! :banghead:
