Re: [Chrysler300] Tire size comparison

[Edward Mills Antique Tractors <millserat@xxxxxxxxxxxxx>]

Stay with P235/75R15 - same size F & R - not sure what you are putting 
them on - but they are a good match for 9.00-14 or 8.85-14 (28.7 to 28.8 
inch OD).

The P225/75R15 may be closer if you are replacing 8.50-14 (28.1 to 28.3 
inch OD).

I tried P235/70R15 on those wheels and had clearance issues at steering 
lock on both 67NY 4drHT and 68 300 2dr.

Anything that lowers the car makes it look wrong at least in my eyes and 
different front vs rear has a number of issues including handling unless 
car is designed (spring rates & sway bar rates) for that setup.
