Grady, The IPC is correct, it's just that 8 X 3.00 tires are no longer manufactured for aircraft. I have however found one for you if you hurry! Check out the tire here. Compare the tread design in the picture to the IPC illustration. This tire was manufactured by General Tire which is now Continental.

The difference is only in nomenclature of tire sizing. The OLD system of outside diameter X Width.... versus the newer system of tread width and Inside diameter. Tread design may vary according to mfr'r as noted. Thanks for that archived pic. Fun to see.

I am posting this to add information to an earlier post I made regarding inner tube design, in which I pointed out that the Mil spec for inner tubes is now obsolete. This is still true.... but new information is: MIL-I-5014 is still obsolete... but military sourcing now mention that inner tubes should meet an SAE standard: SAE document AS 50141. Goodyear Tire and Rubber do not state their tubes meet the SAE standard...but still meet the Mil-spec. (I don't know how that could be since that is obsolete.)
I'm attempting to get that info (but it's elusive.) I'll post it when obtained.

I’m trying to figure out what tailwheel tire to replace my current tire with. Right now, it’s a tubeless Aero Classic 2.80/2.50-4 6 ply with sawtooth tread. I’m not able to find an exact replacement; the tire may be 15 years old.
Is there any advantage to tube vs tubeless? How about tread type (ribbed vs sawtooth?) My inclination is to go with a 4 ply with inner tube. Do the beads seal the same for tube and tubeless?

That’s the way I was leaning, George. Just for my own benefit and understanding... tube vs tubeless? Interchangeable using the same wheel halves, right?
Personally, I prefer tube-type tires because I live on grass with “occasional mesquite” thorns and tubes are easy to repair and return to service... whereas some tubeless-tire leaks cannot. Also the wheel halves are their own source of leaks and tubes take care of that. (An example is a puncture on/near the sidewall ... which is almost a non-event on a tube type tire but will condemn a tubeless type.)
THEN...there are valve-stems... tubes already come equipped... but tubeless assy’s are another possible source of problems.
Wheels must be purpose-designed for tubeless tires, with gaskets or O’rings and sealed. (I’ve never tried a tubeless tailwheel.)
Tubes are just simpler for my mind to wrap-around.
