    Hi,
    I searched around and it wasn't clear. I need more grip from my Charger Hellcat but I do not want to replace the wheels. I have an event next week which is half a mile and I would like to know if it's gonna work and gonna be fine running the half mile with Nitto NT555R 305 35 20 at the rear.

    Moreover, can someone send me picture or video of how they re-shape there inner fender and which one need to be re-shape? Both left and right or just the right one as I can see but some member on here.

    Let me know folks

    Safety wise, you shouldn't go wider than a 295 on a 9.5" rim. Won't give you anymore traction anyway due to it not being in the required rim width range.

    I normally don't recommend installing 305's on anything less than a 10" wheel.
    However I had a set of 305/35-20 NT555R's, that do run a bit on the narrow side, and my take off Hellcat wheels so I put the combo on my Scat Pack.
    The other day I had it on the rack while doing my driveshaft.
    For grins I measured the actual tread that contacted the ground: 9.75".
    Considering that a 275/40-20 NT55R has an advertised tread width of 9.6", I'm not gaining much, it at all.
    My 2 cents? Once these wear out I'll either install some 10.5" wheels to run 305's or I'll run 275's.

    It's not just the section width that defines the safety range it's also the aspect ratio. For example you can run a 305/45-20 or a 315/45-20 on a 9.5" wide wheel ( if it would fit). The sidewall height defines how much bulge there is and how the weight is distributed on the tire ect.

    So did it need the inner fender mod? I hear it is close. But nothing needs to be done if you do not lower the car.

    Yours are not hellcat wheels. Correct? You have some replicas. Maybe a different offset? 9.5 inch? The other guys here on the forum with the Nittos did not have to do the wheel fender mod with the stock wheel and 305s. Thanks

    why is it so hard to post tonight? It will not let me post the first time and I have to repeat the attempt. Now it is doubling up on this board. Sorry about that.
    At any rate someone posted some pictures of the mod. Basically it looks like cutting a 1/8th inch of plastic right along the edge. First remove the button holder. Then make a thin cut vertically around an 1/8th of an inch. Then reinsert the button holder. I have a feeling it would eventually wear away since it is plastic and it would barely hit.
