Performance police interceptor wheel package

[GIGANTORE]

In my quest to build an interceptor meth sleeper, I want to put together the perfect interceptor wheel and tire package. I hate the 20s that are on it. I think they look out of place for the car. And they don't fit the PI/utility look I'm going for.
So the question becomes, how much tire can I get on the 18x8.5" PI wheels? Or, how much wider of a PI wheel could we fit in the wheel well? Wheels are cheap enough that I could have a set widened to say, 9-9.5". And with the wider wheels I'd be able to fit some meaty rubber underneath.

Be interested to hear peoples thoughts.

Before you do all that,
Take the Wheels to a place and have them powder Coated Black....
Then these are your Summer And Drag Rims,
USE the 18" for the Winter, AS the 20" have the best Options for Dragging Street Use, Just saying

Im not a fan of 20" wheels. Even less of a fan of paying for 20" tires.

well:

Performance tire that come on the PI 18's are 245/55R18 Goodyear RSA Cost 143.35 Plus Shipping,

Not Far off from the Pirelli P0's that I have mounted on my 20"s (on Special Closeout about 145.00)
275/40ZR-20 Pirelli P Zero's, ......

I might even be willing to trade someone my 20" wheels for a set of PI wheels.
