Does anyone make an 8.50-6 6 ply for a 180. I only find the 8.50-6 4 ply from Desser.

I believe the closest thing you’ll find to that in terms of diameter are the Goodyear blimp tires.

Several 850x6's out there, but Desser is the only smoothie.
(unless you count worn-out Airtracs, etc )

By rights, a 4 ply tire ought to be good enough for a C180--
the original factory equipment list for my 53 model lists 4 ply 800x6's.
But my North Sound 850x6 STC specifies 6 ply.

FWIW I checked out a set of Desser 4 ply smoothies (can't remember if 800 or 850)
before a buddy of mine mounted them up,
and while just fine for his T-Craft, they just seemed kinda flimsy for a heavier airplane like a 180.

Have the Desser smoothies on my cub and they’re just right. Agree with Hotrod, they’re too flimsy, they’re nothing like the Goodyear 8:50 6 plies on my 180 in terms of “body”.

I felt the same way as you guys, but wanted to try them based on what a couple friends said about them. Got about 150 hours on them (c-180). Been on beaches, mild off airport, and LOTS of pavement. They wear as well as any of the 6 ply tires I’ve used. They’ve never slipped on the wheels and I can’t find a reason not to keep using them. I can air them up good for heavy braking and higher weights and still have a flexible tire. Maybe I’m just lucky I haven’t had problems with them. How many plys are Bushwheels? 3? 4?

The TSO for the desser 850's states a 1600lbs rating, per tire, so as long as your bird is under 3200lbs you should be good.

My GW is 2950. After 150 hours mine look almost the same as they did when I installed them. Happy so far, but I’m not very smart.

Will these work?

I'm curious if the 3200# weight limit is tied to any reg. By that I mean, even a 185 at 3350 will have less than 3200 on the mains, so why can't I use them on a 185. Is there a reg or AC that relates tire rating to aircraft weight, or did we just decide this on our own via internet expertise?

Those smooth dessers have always raised questions among the heavier airplane guys since they are so light. I asked about them for my BH. Rob had them on his C180 and thought they were good until they weren’t. He got a flat from thorns on a dirt strip that he didn’t think would have happened with regular 850s. He removed the smoothies.

I have wondered why Desser has not made the tire in 6 ply version. The demand from 180/185 pilots alone would make it very profitable for them.

Yep, a twig at Angel Point took one of them out. I won’t run them anymore.

Yeah.....if you buy a set of 10 inch wheels.....

Just speculation, but I feel like perhaps some 6 ply tires have fallen victim to thorns as well. I’ve flattened 31s with thorns, but I still run them. Same with 29s on the 180. Ever since I started running stans no tubes I haven’t ever had an issue.

A flat main in the boonies is a real concern for me. I carry a rabbit foot and can of fix-a-flat. Like to know how the 180 flat was fixed in the field.

Most guys carry a spare tube I’m assuming. My 180 is nose heavy, so I have 30 pounds in the extended baggage which includes an electric jack (uses the earthx jump pack). It’s pretty neat. I’ve practiced with it and works well. Also have a small lightweight inflator that runs off the jump pack too. One charge gives several minutes of air and several ups and downs of the jack. Maybe that’s all silly, but I think it might come in handy solo in the boonies.

If a TSO states maximum weight, I don't think you have to go any further. TSO stands for Technical Standard Order.....the standard there being weight rating.

I just have never seen any benefit to these tires, and am baffled by the amount of interest in them. Yes, smooth tires have the advantage of not throwing AS MUCH junk at your tail, but they'll still chuck some stuff at the tail.

And, as lightweight as these things are, they simply can't be very durable. Compare one of these to a Goodyear 8.50 sometime......Yes, the Goodyear weighs more, but it's also much more durable.

Flat tires in the boonies are no fun, for sure. Best thing you can do to avoid those is regularly check pressures. Some of the flats I've seen are from a spun tire, resulting from low pressure. Lots of pilots like to run pretty low pressure on tube type tires these days, which is fine, within reason. But, if you start at relatively low pressure, it doesn't take much leakage to get your tire down to dangerously low pressure.

But, there's no way I'd run these tires on....well, any airplane, frankly. Put some rubber protective shield on the leading edge of your stabilizer, and run decent tires.

Not arguing whether these are worth a damn or not. I agree, they may not be appropriate for a wagon. They are probably great on a J3/PA11 or supercub, or maybe not...

I'm usually pretty good at finding info as far as certifications and regs for modifications. I can't seem to come up with anything as far as tires, and whether or not these would be legal, or could be made legal on a 185. As far as I know all of the 850 STCs for a 185 call for 6-ply, but maybe I've missed one.

I understand just because it's legal doesn't make it a good idea. How does the weight rating of a tire relate to the gross weight as far as legality goes? Or maybe it doesn't? Does it correlate to "corner weight", as in weight on a particular gear?

I could be wrong, but far as I know, the Kenmore 8.50 STC does not say ply requirement. Maybe that doesn’t include the 185? I’ll have to look.

I just checked. Includes 180-180K and 185-A185F.
