I am slightly confused as to this thread - the correct OE size
for the 300L is either 8.55-14 (standard) or 9.00-14 (optional)
with narrow approx 1 inch whitewall. These are unavailable except
in expensive Specialty sizes - frequently made in small batches
using old technology manufacturing processes.
The replacement size evolution for the 8.55-14 is H78-14 to
225/75R14 (also only available in Specialty sizes = Coker or
Diamondback at around $300+ ea). The 225/75R14 are roughly 27.5 in
OD compared to the original 8.55-14 at 28.25 in OD, so a 235/75R14
at 27.9 in OD would be a slightly better match (also $pecialty
only).
The largest remaining non-Specialty 14 in tires are the 215/75R14
(Hankook as previously mentioned - I beileve still available in
Narrow White or Blackwall) (Stay away from any ST prefixed tire
size as they are Trailer tires rated for lower speeds only) or
225/70R14 (Multiple brands but mostly white letters). Both the
215/75R14 and the equivalent 70 series 225/70R14 are smaller OD
26.7 in OD and 26.3 OD respectively compared to 8.55-14 OE at
28.25 in OD.
The better geometric alternate is the 225/75R15 at 28.3 in OD,
but you would need to figure what to do about wheel covers or go
to 15 inch Magnum 500 wheels (used on 67-69 Chrysler products) or
the 15x6 Optional Road wheels used on 71-79 C bodies or other mag
style aftermarket wheels.

You can still order whitewall Hankooks up to 235 75 15s through
Tire Rack. My local Discount tire actually received them in
about 3 days and they were waiting for me to install them. Put
them on my 300L last year. Easy peasy. Just not as convenient as
walking in and getting whitewalls like back in the day.
Diamondbacks are better than Coker btw. Less prone to failures
and a little cheaper ( not much at all) and especially if you
like the correct width whitewalls over the Hankooks 3/4"
standard one.

You'll see the stock size
8.55-14 crosses over to a 225/75R-14.
The issue is that size tire
is only readily available through some of the specialty tire
sellers like Coker Tire and they dig very deep into your
wallet for their tires. Some have great luck with these
specialty tires and some don't.
If you go one size smaller,
to a 215/75R-14, you can easily get a tire at a local tire
shop, but finding a tire that size in a whitewall (like the
original) is harder. A blackwall Hankook tire can be found
for under $100.. Go to a 215/70R-15 and you can find some
white letter tires if that's your thing, but the tire will
be about 3/4" smaller in diameter.
Hope this helps, John Sager

Hello all, I am new to the Chrysler Club/family. I
just recently purchased a ‘65 300 L. I am in need of
replacing the tires. It is currently wearing
P215/70R14 all around but the spare is a P215/75R15.
What is the correct tire size? Can I assume the 14
inch rims are correct?
Steve Grant
