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.

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

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?

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.

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?

To account for the spring gear movement, you need to raise and lower the wheel a couple times with jack to release the toe in tension before doing the final raise. Plenty of battery for this. My jack reaches 18” in height and I use a spring gear jack point block.

I did use it in the field to change a Tailwheel tube and it worked great.

According to the weights I've seen, the Goodyear 8.50 x 6 tires aren't ten pounds EACH heavier, only five pounds each heavier than the Dessers.

I don't disagree that these might work fine on a very light airplane. But, that also begs the question of approvals, which many light aircraft don't have, and where you're landing.

When I owned a PA-11, I ran ABW 26 inch Airstreaks. Yes, the weight was greater than these tires, but I landed a lot of relatively rough places. If all you're doing is pavement, you don't need the Desser 8.50s either.

And, the ABW tires are ALL STC'd for many, many models of aircraft, so easy to stay legal.

The goodyears are essentially the same diameter of the 850 dessers.

The goodyear is 22lbs each, the 850 is 9lbs each, I believe they use the same tube.

I would much prefer the 26 airstreaks, but the cost benefit ratio just isn't there for me. Hard to beat $300/tire that lasts multiple times longer than the ABW. If I had a more powerful airplane that could get in and out of rougher, shorter places then I'd be all over it. Mine are field approved, PITA, but doable.

Anyways, this thread is about 850s for 180/185s.
