RE: [Chrysler300] L Wheel Sizing?

[Ryan Hill <ryan_hillc300@xxxxxxxxxxx>]

I hadn't realized Imperials used a larger bolt pattern and stud than all other large Mopar cars. I guess I assumed Mopars were all 5 on 4 1/2, other than the small bolt pattern A bodies. Ford also used the same 5 on 4 1/2 pattern for many many years and in most cases the wheels are interchangeable.....the only issue being the hub center on Mopars is slightly larger from my experience.
 
If I'm understanding your warning Ron, you're concerned about sheering off the 1/2 inch studs of a wheel with 'only' a 5 on 4 1/2 bolt circle because of the added wheel/tire width? (I suspect because of added traction?) Unless the studs are fatigued or greatly weakened due to corrosion or misuse, there is more than edequate strength. This is the same setup that has endured millions of burnouts, launches, and other abuse by Mopar and Ford owners driving some of the hottest musclecars for 50 or more years. Yes, drag cars are upgraded to stronger and longer studs when huge slicks and big HP are added, but I can vouch for the standard 1/2 inch studs being more than adequate, even under extreme street conditions. No worries there in my opinion.

Hi, David:

When I put larger tires on my K, one tire rubbed on the inside of the front 
right 

fender. Maybe the rubbing was peculiar to this car. As such, I would check the 
clearances on both cars before making the change.  

Also, check the bolt pattern on the rims you want to use. Both the '64 and '65 
300s
came with 4 1/2" stud hole circles on a 14x6 rim. The larger rims you want to 
use may very 

well have a larger bolt pattern. For example, a '65 Imperial has a 15x6 rim with 

a 5 1/2" bolt pattern, requiring new hubs and drums . The studs are also 
larger, 9/16"-18 

instead of 1/2"-20, requiring a new set of lug nuts.

Hard spinning a tire mounted a 15x8 rim with only a 4 1/2" bolt pattern may 
shear off
the studs, causing the tire to fly free of the car. I've seen this happen at a 
cruise night
a few years back, much to the embarrasment of the driver.

Hope this helps.

Best,

Fellow 300 Enthusiasts,
As I'm going to be ordering fresh tires for my L shortly, it'd be helpful to 
have an extra wheel/tire combo that can be moved between my L and K for 
increased flexibility. 

To that end, would 15x8 (rear) and 15x7 (front) wheels work on an L? It's 
important that the width and circumference of the tires themselves clear all 
parts of the body/chassis including straight ahead, full turns and with spring 
travel. 

Another option would be to go with 15x7 all around on the L so that the tires 
can be fully rotated.

Appreciate any suggestions on the topic. 

Best,

David Morrison
