    I found these Niche rims.. they look similar to the factory.

    They offer a 10.5 for rear and a an 8.5 for the front in 5x115.
    Targa - M130 - Niche Wheels

    Here are the stats on each.

    Rear:
    M130200590+20 MB -Black Machined 20 x 10.50 5x115 20 Offset 30.00lbs CONICAL 0
    According to offset calculator with this rim, there is .59 inches less inner space. Would this work?

    Front
    M130208590+15 MB -Black Machined 20 x 8.50 5x115 15 offest 28.00lbs CONICAL 0
    According to offset calculator there is .6 inches more inner space which is fine.


    I am thinking of the following combo.

    Rear
    10.5 Continental ExtremeContact DW 315/35ZR

    8.5 Continental Extreme Contact DW 245/45

    Both of these tires are exactly 28.7 which is factory height I believe.

    Do you think it will clear the rear with that extra half inch?
    Is there some issue I am not seeing with this combo if the rear did work?

    Take a nickel lengthwise and go from your rim to inside and see if it clears.

    Why do you want less tire up front?

    Not sure if your interested,, but you can have your factory rear wheels widened for around 500 dollars

    I dont really want less up front but the only 5x115 in this same wheel they make is 8.5. Unless i go 10" up front but i dont think that will work.


    I dont have my car yet.. Getting it friday. If anyone has a chance to maybe measure the clearence?


    But what about the 315s? They are almost 12" wide i believe. Would they rub as well?

    Same as mine.... Are you sure a 8.5 wide wheel will clear your brakes in the front.. There is a place in Livonia Michigan called weld Kraft ( I think that's the name) that can widen your factory wheels,, something to think about

    Wheel width shouldn't affect break clearance. They are still 20" high.

    These are everyday show rims, factory fronts would look to different. For drs i wouldnt care

    No i have no illusions of track or twisty racing with this car. I just want straight line speed but also manageable daily driving

    How so? The 8.5s offer more than 1/2 inch more inner clearence? Or are you talking about turn performance? 245s are still a pretty decent width tire.

    Well Noquarter I'm glad you took my advice with the 10.5 inch wheel for the rear and the 315/35 tire.
    The Continentals are the same tire I got. Had them on my 5.0 Mustang and they work great, but are squirrely when cold.

    I think you meant to say 275/40 for the front wheel correct? You wrote 245/40. I wouldn't go skinnier than the factory 275/40 tire upfront. These are heavy, and front heavy cars. You want the grip of 275's up front.
    As for the 8.5 inch wheel up front....my only reservation would be that it won't have much of a "deep dish" feel and may look a bit "average" on the Hellcat.
    Stick with the stock 9.5 inch width or if need be due to offset clearance issues, go to a 9 inch front.
    Or go to a 10 inch wide front wheel with the 275/40 tires. Only hitch here is the 10 inch front wheel will need an offset that move MOST of that additional 1/2 inch in width to the OUTSIDE.
    In the front there is very little clearance between the wheel/tire and the upper suspension assembly. So going to a 10 inch wide front if the offset places any more than a few millimeters of that additional 13 mm (1/2") towards the inside, it'll rub.

    And yes, welcome to the struggles of finding a good wheel and tire package for these cars that offer the staggered look in the correct (and very limited clearance) offsets.
