2 piece AMG's on 500E help please.

[vcci]

I really want to put these 2 piece amg's on my 92 500E. I have read many posts here and am somewht confused as to the right sizes so I will ask a few questions before going out and spending money hard earned.

1. Is the right size wheels for the 500E? 18x10 and 18x8.5?
if not what is the correct size?

2. What size tires to put ? my car is not lowered and I am not planning on lowering it. I dont want any rubbing but I do want to fill up the wheel well as much as possible.

3. What offset should i get if I want them to be perfectly alligned with the fenders. I dont want them sticking out more then the fenders but I dont want them hiding inside the fenders.

4. and finally what is the best tire out there in terms of performance and life span? I want them to last as much as possible but still handle great, i dont do any track racing but i do take it to a canyon every now and then.

any and all help and suggestions are greatly appreciated. I know many of you are very knowledgeable with these cars so i know i am getting the right help.
