What rear end do you have? What suspension are you running? Do you have any fancy control/strut arms/bushings? Brakes? What year Charger? All are details that are going to help us, help you.

The easiest method is to take some cardboard, and make a mock up wheel and measure. Compare your current wheel and tire setup to your new wheel and tire setup with this site: https://rimsntires.com/specspro.jsp

I run the exact same Nitto tire sizes on my 69' Road Runner. Stock style suspension, upgraded (Hotchkis). Tires will rub the sway bar under full-lock. I run a bit more modern wheel, clears Dr. Diff Brembo style calipers. You should be slightly ahead with less backspacing I would imagine, as I run .200" spacers front & .375" spacers rear.

Fronts -
Size: 18X9
Offset: +1.4"
Backspacing: 6.38"
Weight: 23 lbs

Rears -
Size: 18x10
Offset: +0.9"
Backspacing: 6.36"
Weight: 25 lbs

I’m be running all stock suspension as of now with 2” lowering blocks in the back but I do plan on upgrading my suspension and brakes next year. So you’re thinking I should be good?

68-70 b-body wheel well design should be similar, but i'm not an expert, there may be slight differences between makes and models. I would like to say 'yes, you're good' but even different brands of brake kits / rotors can add or remove track width. I'm running Baer rear discs (Cobra) and a dr. diff stage IV kit on the front.

All I can say is this wheel backspacing works on my b-body and an a-body application as well.

Here is a chart that may help you! May be beneficial to grab a few measurements before you order like others have stated.


I would be sure to give US Mag a call to verify if that specific wheel will allow proper brake caliper clearance with the kit you plan on purchasing in the future.

I’ve seen a few people use this chart with success. I thought about using a 18x8 for the front which had a 4.50 backspacing and +1 offset and according to the chart that would only have me +1 off and the back rim which is 5.25 backspacing with +8 offset and according to the chart I would be off +2 with the offset. So if I am reading the chart correct my I shouldn’t have any problems with putting the 295 on the back??? Thanks!
