Default Coker tire question

I can call Coker tomorrow before I take my tires and rims to the tire shop, but thought someone might know the answer.

I received my new tires (Coker 600x16s, ordered through Summit Racing). They're blackwalls, but have a raised area on one side like where the whitewall would be. The other side of the tire is flat in this area. The flat side is also where the colored dot is that I think is supposed to line up with the stem hole in the rim.

Anyone know which side of these Coker blackwalls is supposed to face outward?

Those tires are not directional specific so you can place them as you prefer.

I am fairly certain the dot is the heavy degree of the tire. If I am recalling correctly, you'll want that set at 180° from the stem.

I just mounted a set of Coker tires yesterday for my 36. I had the flat side mounted out and dot 180* from stem

I don't know a whole lot about anything but...
I believe that the thick rib on a Firestone Deluxe Champion
is mounted on the outside of the wheel. The raised rib
is there to rub against the curb so as to protect the
white wall from scraping. Black walls and white walls
were made/are made in the same mould so the rib is still there
even on black walls. I suppose Cokers are the same.
Just my $.02.

My understanding is the Dot is the lightest point of the tire, and should be lined up with the heaviest point on the rim (usually where the the stem is).

Dot is normally fitted by the valve stem.

Hi all; From my aircraft mechanic days, The raised rib on the sidewall was a spray deflector. mounted to the outside it helped deflect mater/slush away from your car body/ aircraft eng and propeller. I mounted my Firestones with the rib to the outside. The front tire on a a light aircraft would have ribs on both sides. Make sense to you all? Newc

I called this morning. They said it's my preference. A little hard to be confident without comparing in real life or photos. But decisions like this?--that's why they pay me the big bucks. 😄

I decided to go with the black-wall bump outward. Here are pics of inside and outside. Don't think it makes much difference as long as they are the same.

IMHO; I think that it looks better & more correct with the "bump" outward.

Swapped out the old wheels & tires for the new ones today while it was pouring outside. Believe me, the California drought is over. We're over our yearly total, and the year runs from Oct 1st to Sept 30th. Got a long way to go yet.

Wheels and tires turned out great, and it only took me 30 or so minutes to find where I'd stashed the hubcaps 4 years ago. :-)

Now to work on a dozen other little details and one big one: the top.

So what did they (Coker) say about blue dot? I never considered the blue dot when mounting mine and they seem fine.

The painted dot usually denotes the lightest part of the tire and should be alligned with the valve stem. This will minimize the amount of weights needed to balance a tire.

It has always been my understanding that the dot went in line with the valve.

is the valve heavier than the metal it displaced?
