Hi, gonna put some stuff here to help me remember when i try to find custom wheels i wanna buy for the "Cookie Monster"..... Haaa

Tire sizes car could have come with
Stock Wheel Size: 18” x 7.5”
Stock Tire Size: P225/60R18 widest i can go 255/55R18

Stock Wheel Size: 17” x 7” Wheels stock offset = 15mm
Stock Tire Size: P215/65R17 widest i can go 235/60R17

For size comparison Rock Auto sells a wheel for 2009 300 2.7L with
18 X 7.5
bolt 5 X 115
offset 16mm
backspacing 125mm = 4.92"

Offset measures the distance between the wheel’s mounting surface and centerline
Backspacing measures the distance between the wheel’s mounting surface and innermost lip

steps
1. rim diameter big enough to not hit the calipers, etc....
2. rim width not too big it hits car when turning
3. bolt pattern must allow wheel to fit on car
4. offset must not allow wheel to hit car body parts
5. backspacing must not allow wheel to hit suspension parts

Wheel i like and found on tirerack.com

• Size:18x8
• Offset:20mm
• Backspacing:5.28" = 134mm
• Bolt Pattern:5X115mm
• Rec. Tire Size:225/60-18

Also found https://www.discounttiredirect.com/buy-wheels/vision-legend-5
i picked 17 X 7 with 5X115 and offset 6 in GunMetal with Machined Lip

Will these bolt on my car with no issues?

I need to figure out the math to understand why my stock wheel with 15mm offset and the wheel i picked with 6mm offset both fit the car fine, according to the discounttire site ??
Thanks.

Tirerack had pick with 20X8.5

If you haven't already, please research the reliability issues of the Chrysler 2.7 engine before you sink that kind of money into your 300.

Hi, thanks for your concern, but we should stop drinking the "kool aid"

Dodge / Chrysler 2.7 Liter V6 Engines

Dodge / Chrysler 2.7 Liter V6 Engines Willem Weertman wrote, in his engines book, that the 2.7 liter engine started with Francois Castaing's believe that an advanced, lightweight, efficient engine was needed to secure Chrysler's reputation. The engine was, therefore, a new design using...

This part.....

"The 2.7 liter engine originally had a tendency to generate sludge which caused engine failure. Similar problems have been appearing on Toyota and Volkswagen engines. We were told that, shortly after the first reported cases, Chrysler isolated the problem to the crankcase ventilation system; hydrocarbons were entering the oil and breaking down the additives. This problem was solved (around 2002-2004), and the number of engine failures appears to be small. "

Hi, your link to lawsuit seems to account for status up to 2007 and mentions engines from 1998-2003.
I tried reading comments and they were all over the place so that was no help.

I am still confused, how do you relate a 2009 2.7L to this lawsuit ? Did you find documentation engines made after 2004 and owners provided proof they kept up with maintenance were experiencing engine failures ?

I saw the article mention in 2009 a bunch of lawsuits were combined so one judge could streamline the proceeding....

Are you a victim of engine failure ?

I provided that link as an example of why your quote from Allpar, "This problem was solved (around 2002-2004), and the number of engine failures appears to be small" should not be taken seriously. If you're looking for a highly-simplified summary, consider this quote from Wikipedia's article on the Chrysler 2.7 LH engine;

"Buildup of oil sludge is a common issue that plagues this engine. Higher than average operating temperature, an insufficient oil capacity and the timing chain driven water pump leaking into the crankcase are all factors in why this occurs .[3] The 2.7 L V6 engines have suffered from oil sludge contamination.[4][5][6] In February 2009, five separate class action lawsuits related to the alleged oil sludge defect were consolidated to the District of New Jersey.[7] During the Chrysler bankruptcy proceedings, there was concern among consumer advocate groups that Chrysler's proposed "free and clear" sale of assets to "New Chrysler" would allow the automaker to avoid liability for the oil sludge defect.[8]

The engine was affected by an oil sludge problem and premature timing chain tensioner failure. The oil sludge issue appears to have been caused by issues with the crankcase ventilation system, and while it affected a minority of engines, it could cause complete failure[1] In some cases, neglected maintenance aided in premature failure (missed oil changes or increased intervals between oil changes). Also this engine was plagued with issues regarding the water pump gasket leaking coolant internally and diluting the oil. Such coolant leaks must be addressed instantly or engine failure is imminent.[9]"

The reputation of the Chrysler 2.7 is very well known in the enthusiast community and the auto repair industry. If you'd like to learn more about it, I'd suggest you Google "Chrysler 2.7", read some of the articles, watch a few YouTube videos, and come to your own conclusions. If you would rather just believe that the reliability and durability of the post-2004 2.7 is average or better, that's fine with me. The reason for my comment was to try and help you avoid a situation where a potential catastrophic engine failure leaves you with a car that is not worth the cost of repairing it, and on top of that, you've lost whatever you may have spent on aftermarket wheels and new tires.

Gotcha, thanks. I actually did stumble across that Wiki when car shopping. It's tough to decide when you need to take your own situation into account and weigh the statistics.
We decided to take the gamble based on our 2009 had 113K and carfax did not show engine replacement ( i know carfax is notholy scripture).
If fact we did our 3000 miles and its getting the WP and Timing Chain replaced to give us a base line as we don't know our cars history. Even though our first 3K with the car have been very pleasurable.

I am a gearhead so i can research, and have turned a few wrenches but i am no expert.
2 months after getting this wife got a 2012 Sub Legacy, she loves it and i don't know crap about the drive train, they don't even have a tranny dip stick !. All the watercooler talk is they are a good bet. Ours has 120K on it.
Have a Good Week.

Most LX cars don't have one, either.

If yours does, it either has an aftermarket dipstick, or it's a 42RLE 4-speed.

Good luck with both cars!

 

[DeepBlue]

Thanks, yes you are correct, i was bummed no dipstick. I was cheap and got the one you have to store and can't keep in the tube. I think B&M makes the one that stay in the tube like a "normal" tranny dip stick.
Later.

This is best idiot proof vid for me explaining dimensions you need to understand when picking wheels.
