That is very generous, thank you. We are using an Ivoprop and the problem is the
length. We have tried taking the pitch out and that helps, but in order to make
the engine behave, we have to way under pitch it. So we are going to shorten
it down as soon as we figure out what length it needs to be.
And to Rick Neilsen: just as an experiment, we got several super bright LED strips
and hooked them up to a cheap sequence flasher to see how they worked as strobes.

You can see them from a couple miles away when it is almost dark, but they are
no way as bright as one of Dick Kuntzelman's units. They main thing they have
going for them is they were cheap and it was an interesting way to spend an afternoon.
OTOH, if there is anyone overtaking me on final, they'll for sure see
it!

| Subject: | Tires, wheels and brakes? |
Greetings,
I'm working on an old Slingshot, and it currently has Van-K 6"x4" aluminum wheels,
and MCP hydraulic brakes. These seem like quality items, and I have no problem
with either, other than the fact that I'd prefer split hub wheels to these
one piece wheels.
The problem is the tires. They're ancient, and really low quality Duro tires that
appear to be for mowers? The size is 15 6.00-6. The wheels don't allow the
use of tubes, and aircraft tires in this size are rarely tubeless. I think
there are a few, but they're over $300 each, and for that price, I'd rather just
replace the wheels and brakes (if needed) to get split hubs.
Question 1- Is there a good quality tubeless tire that will fit these wheels?
I will be operating almost entirely from paved strips. I'm very hesitant to
run lawnmower tires on a plane, since I'd hate to have to explain to the FAA why
I installed tires like that if there's an accident involving one of them.
Duro, Carlisle, and some others exist in a 15x6.00-6 size, but even the 4ply doesn't
inspire confidence.
Question 2- If there's no reasonably priced tire for these wheels, is there a reasonably
priced tire/wheel/hydraulic brake package that uses aircraft tires?
I was looking at Black Max, but those seem to have the same issue as what I have,
except that they do offer split hubs. Their tires are Carlisle, and I'm
not sure if you could use a tube and aircraft tire with the Black Max wheels.
Thanks,
Rusty

The Carlisle tires are junk. They are made for golf carts. Kolb originally supplied
them on my Xtra. I replaced them with Goodyear Aircraft tires. They are
expensive but worth the money in my opinion. I use Matco split rims and went
with two Matco calipers on each wheel. I also use tubes. Very happy with the
results.

I don't spend money I don't need to, that is why I have a VW on my MKIII. I
have been flying the Carlisle tires since I got them with my Kolb kit. They
have served me well. They do shake a bit till I touch the brakes after take
off and that maybe is a need for balancing? I have had a few flats from
leaking Matco wheels and a few pinched tubes but that isn't the fault of
the tires. Most of my flying has been off grass so I haven't had much wear.
A few years ago I moved from my own grass strip to a real airport with
paved runways so now my tires need to be replaced but that is 26 years of
service. Will you get better service from aircraft tires?? I don't like
paying insurance and a bunch of lawyers that add no value to aircraft parts.
As usual worth what you paid for it.

To expand on this (I was previously typing on my phone), the tires are
6.00-6, standard fare on most small/mid size certified a/c, and were
removed from the Citabria at annual due to wear (only a hint of tread
groove still showing). Intended for tube operation on split wheels. I
mounted them on the one-piece wheels on the Kolb without any tubes. I've
probably added air to my RV's tube type, split rim tires 3 or 4 times
since installing the Kolb tires, and have never added air to the Kolb. I
really didn't know if running them tubeless would work, but it seems
that as long as the tire (and its bead) and the rim are both in good
shape, they'll hold air for a looong time.
If 6.00-6 tires will fit your rims, it might be worth taking a shot at
picking up a couple of freebies, like I did. A busy maintenance shop
likely has several pairs lying around.

Thanks for all the comments. I pretty much expected opinions to vary from use
anything that holds are, to use only certified tires.
I understand the Carlisle (and other cheap tires) tend to have balance issues,
and balance weights will likely end up in the prop as part of Murphy's law of
pusher engines. Other than the fact that they don't rate them for speed, the
4 ply Carlisles seem sufficient for the Slingshot. The path of least (effort
and financial) resistance would be to try a pair, and since they're only $23 each
from Amazon, I might just do that.
BlackMax told me they don't make wheels for tubes, but they do have a 6x6 wheel
that has the hole in the center, where it would be on a normal split rim. It's
a one piece wheel.
Desser said they have a Aero Classic tubeless tire for $226 each. Sounds like
it's a Cirrus tire. It's 6 ply, which is way overkill, and from what I understand
the higher ply tires are very hard to mount on one piece wheels. BTW, I
always wondered why most aircraft tires need tubes from how well the beads tend
to seal. I guess the split in the rim is the typical reason. It might be worth
trying some cheap 6x6 aircraft tires without the tubes on the one-piece wheels.
Finally, there's Matco, which may be an option, but they have so many confusing
types on their page that I eventually give up after staring at it for a while.
Thanks,
Rusty

Rusty, I=99ve basically ran those very brands for many years. Your wor
ry is not realistic. I now run Black Max brakes and one piece wheels. I have
two sets , 6=9Dinch wide for my booney tires 15 X 6 and 6X4 Aero som
ething from Aircraft Spruce for paved runways. There rated for 70 mph.
Both set are mounted tubeless. I=99ve never in 34 years of flying ultr
alights had a blowout.

Instead of using stick on weights inside the rim. I took a tubeless
tire patch taped it on the light side of the tread till the tire would
Ballance. Un mounted the tire mount the patch on the inside of the
tire tread.
Remount the tire using talcum powder to keep the tube from sticking to the
patch. Keep the bead of the tire free of talc.
Balanced tire with no visible weights to fall off.
Just mark the tire, rim and tube so final assembly is the same as when
first tested.

Just to give a little background on my experience with Carlisle tires. I had about
140 landings (on pavement) with the ones furnished by Kolb. The Cord was
showing so I replaced them with another set of Carlisle's. After installing
on the rims I added about 6 oz. of weight on one and it still would not balance.
I then noticed that the runout on that tire was well over 1/2 inch in one
spot. I think the cord was overlaped too much (made in China). I also had a
very difficult time seating the tire on the rim due to poor manufacturing tolerances.
I decided to run it anyway and see if it was a problem. At a very, very
fast taxi it was hardly noticeable. At a normal taxi speed it was like going
over a 1/2 +" high speed bump and was in resonance with the landing gear. Very
bouncy, not good.
I then replaced them with Goodyear 8.00-6 tires. They seated on the rims very
nicely and had no noticeable runout. They are also 6 ply where the Carlisle's
had 4 ply. The downside is that the Goodyears are about 2.3# heaver per tire
and of course the high cost. Anyway, we'll see how long they last. My landings
are much slower and better now so that should help.

I forgot to add that the Goodyear tires required very little balance weights.
I think I used about 3/4 oz on one and a little more on the other. Not sure it
they really needed it but decided to balance them anyway.
