I'm "told" that current tire making technology limits use to a single type of rubber
compound. Hence you either make it soft for adhesion or firmer for good
wear. So a balance is struck between different compound characteristics. When
a tire is recapped, the process allows the application of a "best wear" compound
to the tread, while the carcass remains what it started as.
In my experience, this means that re-capped Russian and Chinese caracasses are
superior in wear to both Desser and Commie newbies. This I verified by looking
through my log books. I DO NOT run my tires down to the plies but rather send
them in for recapping while they are still quite serviceable.
So far my "average" tire times are: Commie tires on hard surface - 110 hours, Desser
newbies - 220 hours on hard surface mostly, and recapped Commie's get over
300 on mixed grass/hard surface.
BTW, my last batch of Desser re-caps came with the wide, extra deep squared off
tread. I was so impressed I talked a Yakker into selling me his old "useless"
Russian cores so I could immediately send them in for recapping. I have no shame.

I've been reading the remarks on Desser tires and just wanted to
mention that Aviation Consumer ran an article on tread wear a few
months back.
The conclusion of their testing showed that ( against the standard tires
available for GA aircraft )
that Desser tires were equal to the top of the line Michelin on new
tires and that the Desser recaps were superior ( in tread wear ) to
anything else available.
I have been using their tires for years and when I bought my CJ and it
needed tires I got Desser tires for it as well. I have had only good
experiences with their tires personally and get very long tread life
from them. I operate off of concrete and asphalt at Reno/Stead airport.
I've never used a Russian tire but the Chinese tires are pretty soft
compound and wear quickly.

Agree, my Dessler's ,new, have held up much better than the New Russian
tires that came on my YAK. I still have not had to change out my Dessler's
with just about a 110 hours on them. My Russians lasted about 50 hours on
both concrete and grass (they type you cut and taxi on, Jon. Don't do the
other.).
No Craig, you can not have my carcuses. I'm sending them back to Dessler to
be recapped.

Yakkers;
In 5 yrs of M14 yak flying the possibility of a "blubber" on take-off
has been a given. The guy that sold me the airplane warned me about it
and i warn my GIBs. I always thought it was loading of the lower
cylinders or something like that and just lived with it. Now the
experience is getting more frequent and prolonged. People on the ground
are noticing. Used to be i'd get a little miss at 500' when climbing
out, now it's at 200' and lasts for 10 sec. Oil & fuel pressure stay
solid, can't say abt RPM & MP since the needles are longer and they are
shaking too much at that point to be conclusive .It's always momentary
and does not repeat during all the unusual attitudes of the following
acro flight which should eliminate a lot of possibilities. I'm
religious about having temps in the green prior to take off. If the
plugs are shorting out due to extended run-up/warm up then what would
make them heal themselves in a matter of seconds? What going on? TIA.

Yak friends.
I recently found a great site for viewing TFRs and also online sectional
charts with the TFRs built in.
https://www.tfrdod.dins.jcs.mil/TfrDOD/
Just completed Annual Condition Inspection on my Yak.
Did a thorough FOD inspection through all the airplane and deep into the
tail.
Clean and clear.
FOD checked lately??
