Any pics of b body with 18” or bigger wheels ?

Tire size and rim information please.

I’ll get the details tomorrow. Rim is 15x10. Not sure of offset. Maybe 4 1/2”

OK...Great thread! Now here's a problem for yas. I'm just finishing my build on my 70 RR . The front suspension is an HDK with the original Mopar spacing ( which I see posted on other sites as 5 x 114.3 OR 4.5 inch) and the rear of the car is a 2015 Challenger independent suspension which as I see it posted on other web sites as 5 x 115 OR 5 x 4.5. I know there's a difference in bolt patters although be it less than 1/32 of an inch. My problem is finding wheels that will be made in both bolt patters so that front and rear look the same ( and NOT use adapters). Looking for black wheels - 17 inch for fronts and 18's for back.....wanna keep as much sidewall as possible to keep the look of a 70's era car..

Actually, .7mm is only 1/64 of an inch. Really ... not worth worrying about !! I'd be getting "hub cebtric" adapters for sure though.

Thanks but I did mention I didnt want to use adapters.....

If you're an engineer, that difference could be the death of you. If you are a normal guy, it isn't enough of an issue to matter.
The spacesaver spares in my two Chargers are from late model Chargers.
One problem of yours that I see is the rear track will be much wider than the front meaning you'd need a wheel with a lot of backspacing in the rear while the same type wheel up front will look way tucked in.
Me? I like the wheels to all sit closer to the wheelwell edges like so:

Even in my car above, the front wheels are tucked in a bit more than I'd prefer but they fit and clear.

HA ! - I am an Engineer.....but besides that...what do you refer to with your comment Spacesaver spare (which I know as a spare tire) ....and here is a pic of my car in Build Stage with late model Charger 18 inch wheels I use just to move the car around on........Same wheel front and back seem to fit wheel wells pretty good...

There’s a big difference between an “adapter” and a “hub-centric” adapter !!

I didn't think of the differences in the "hips" of the Plymouth versus the Dodge. The Charger rear quarters bulge out more than the Plymouth. This makes stock width tires look sucked way in on the Chargers. Deep offset and less back spacing helps make up for that. My rear wheels are 18 x 10 with 4 3/4" backspacing which works out to about 6 1/4" of front spacing since aluminum wheels are often a full inch wider than their rated width.
The Plymouth has lower wheel opening arches and are not as wide overall at the "hips".

A more detailed search presented the piece your speaking of. Thanks ! Ill have to see if they make a setup to center the 2015 wheels to the 1970 bolt pattern.
