I have a friend with an '09 Charger base model who is wanting to put wheels and tires on her car. She is not a car person and has been ripped off by car places before and I am trying to help educate her a bit so this doesn't happen again. I cannot go with her to tire/wheel/car shops because she lives in Nebraska.

She has stock 17" wheels/tires on her car and wants aftermarket 20's. Is this possible with proper backspaced, offset and width wheels without other modifications (please remember I am a truck guy)? Also, just for her knowledge, what is the proper backspacing, offset and width for a 20" wheel on charger? I also need tire sizes to compliment all this info as well.

Thanks guys, I greatly appreciate your input.

Hopefully Art will see this...as far as I'm concerned he is the go to guy with anything to do with the Charger...

Ohh man 20s no problem no mods, the tire size will depend on how wide the wheel is but it should be about 9-10" wide

here is a good un

I was gonna text him about it in a bit.

Speaker of charger guys....where's Jimmy been lately? I haven't seen a post from him in awhile.

I was running 20's with 275/40/20 on all 4 with stock suspension and had no problems. I am now lowered 2" with the same wheels and tires and still don't rub.

As for offset and such, I will have to check to see what mine are. I have the Viper replica wheels.

My wheels are stock 20's - running a 245/45 tire. I'd have to look as well for the offspacing and such as well. I'll take a look after dinner.

Thanks guys, good info. Looking forward to further details.

Most of the wheels from any LX model should work. Most of the wheels are 9" wide. That allows for rotation of the tires. Jimmy, Art, & Ross are definitely the guys to talk to.

bolt pattern - 5 x 115 - offset - 15-25 or 15-20... for RWD

AWD may be different

**NOTPAID4** · 07-26-2011, 10:51 AM

Yup the correct bolt pattern is: 5x115
The correct offset for RWD is +13 - +18
(You can find the offset on most wheels on the back "ETxx")

The recommended size tire for 20's is: 245x45x20. Many SRTs come with 245x20 on the front and 255x45 on the rear.
(As stated above 275x40x20 will also work ~ a little more rubber)
You can also use 295x40x20 on the rear with at least a 9" wheel.

AWDs have a larger offset, believe +35-+45

I have SRT Challenger and SRT Magnum wheels on two of my magnums and these require a 3mm spacer to clear properly. No problems at all with these; they are so small YOU will never see any difference.

BE AWARE: If you have the tire pressure monitoring systems, each year uses a different frequency and IF you use the wrong year you will get "wacky" readings on the monitoring system.... Ask ME how I know? LOL

If I can help anymore, just ask!

NOT SURE if you are aware of this but you can also use some FORD type wheels with a bolt pattern of 5x114.3. I have a set on Tee's DEMON car that were bought originally for our Ford Explorer and I did use a 3mm spacer on these too and have had NO problems in well over a year NOW. Like I stated just make sure you check the offset!
