    Largest wheel/tire and at what offset for safe Fitment?

    Going to keep my stock 9” wheels for my winter tires and with some Black Friday sales going on I’d like to snag a good deal on some wheels.
    I’m kinda at the analysis paralysis stage after reading through older posts but some observations I’ve made are that 315mm tired seem risky. Some rub, some don’t.
    Am I safe running 10.5” or 11” rear wheels with 305mm tires? For offset it seems like around 25mm should be good correct? I have the standard brembos if it matters.
    For fronts I was looking at 10” wide wheels with 275mm tires. Any Fitment issues with this set up?

    Sorry to beat a dead horse, but the more I read the more differing opinions I read and was getting confused.
    I’m looking at wheels from Ferrada, variant, or rohanna.

    Stay with 9's up front. Too far in rubs the spindle, too far out rubs the fender well on bumps and full lock turns (most of the time). There IS a perfect offset but I have no clue what it is.

    The rears, honestly, with 10.5's or 11's, +18 - +22mm is the range you want to stay in. You already know my 10.5's/ +25mm have a 6mm spacer, but I run that more for peace of mind (it also lets my Drag Radials clear no issues, so I just leave them there).

    The difference between 305 and 315's is less than 1/4" on each side, so there really isn't much difference in traction or looks. They're both wide lol

    Maybe I’m not thinking of this right. If you say 18-22mm offset is what to shoot for, wouldn’t your offset be closer to 31mm (25mm offset+6mm spacer).

    You are actually decreasing positive offset pushing the wheel away from the hub. So more like 12-18mm+ offset

    Ok, I thought moving the wheel mounting location farther away from the center of the rim was an increase in offset. Adding a spacer would push the wheel further out towards the street and would increase that distance. So how does a spacer decrease offset?
    Larger the offset the more risk you run of hitting the outer fender, the less offset you run you increase rub chances inside the wheel well correct?
    I would also think with a wider wheel, you will get more concavity to the look of the wheel as well correct?

    No offset works like this I’ll use a picture to explain it.

    Adding a spacer moves the whole wheel out same as moving the center of your wheel inward. Hence decreasing POSITIVE offset.

    Factory Reproductions guys told me with a 10.5" +25 in the rear and a 305, no spacer needed, if you want 315, then a 3mm spacer is needed.. I have the dynamics package with 9.5 +15 in front and have a stock 275 that runs fine. I just got a set of FR's from a member here that are 9.5 +15 and 10.5 +25 and have 275's on front and 315's on rear... member told me he did not have any rub except every once in a while. The tires are Atturo's.. Unfortunately, a 315 in one brand is not exactly the same as another brand.. I will probably get the spacer anyway just for piece of mind, and I will be switching out to toyo tires once these run out.

    Stick with 9" in the front. 10" will work as well with 315 or 305s.

    Here is how the 305s look and I cant hardly tell the difference between the 315s I had on previously.

    Since my setup is widened to the inside I am running a 10mm spacer with extended studs.

    My 19 Scat Pack came with 9.5" x 20 wheels all around with 275 tires. I have the 6 piston Brembo's up front. 4 piston Brembo on the rear.

    The offset of those is lower to accommodate the extra width up front. I think the op wanted about 25mm but the 9.5" can accommodate a 285/35 for a bit more tire up front. The 9" can too with a 3mm spacer.

    Take a look at 2016 Dodge Charger Fitment Gallery 20in Wheel Diameter | Fitment Industries The site has a pretty good selection of wheel/tire combo's for our cars in the gallery.

    I'm running Vertini 20x11's (21et) with 305's in the rear and 20x10's (26et) with 275's in the front.

    If you look on the Hellcat forums, there are a few guys that post pretty regularly advertising wheel/tire combos for decent prices. I picked mine up from a guy named Jon at Best Wheel Deals and he was a huge help. I wanted deep and wide and he got me exactly what I wanted at a price point I was good with.

    Good luck!
