I air up without the valve stem and hear that pop when the bead sets, then let the air escape and then install the valve stem. I have always used 12-15 psi on 8.50s and 26" Goodyears.

How do those slick 8.50's and 26"res wear on pavement? Have the opportunity to grab a set of slick 8.50's, but most if not all of my wheel ops end at a paved airport. Do they wear similarly to the larger BW's? Sorry if this is a repetitive question but I couldn't drag up anything relating to the smaller wheels in a search.

I'll be 50/50 to start. Then about 100% this summer.

If you are on pavement a majority of the time, I'm not sure you will benefit from larger tires, my home strip is grass but a bit rough, hoping these 8.50s will smoothen that up a bit.

I've had 8:50 Dresser' (I sold them when my wife laughed at how tinny they were), GY 26 (more like 25's) and BW 29's. BW's are soft and don't wear well on payment, but they are the best in the rough. GY's are more stiff but, wear better. 8:50's are.....smaller.

I think they look very nice and with you living in Colorado they should see plenty of off airport landings. what wheels and brakes do you have (Cleveland)? Did you have any issue with tire rubbing on the brake calipers? Do you mind showing a picture of the clearance between the tiers and the brake caliper?

Again, I think it looks nice and is probably all you need for the most off airport operation.

Pacer N3342ZThanks! I'm actually flying this pacer to Bettles, AK this summer and moving permenantly to Homer, AK in the fall. It will see alot of non paved strips up there!

I do have single puck Cleveland's. And there is very little clearance between the tire and the brake liner. But being the caliper is mounted about the 3 or 9 o clock position, I don't think it'll rub at all. Some wheels requires spacers for just this but my research (or rather Steve pierces) shows no spacers are needed. Sorry I don't have any photos of that though.

26" Goodyears wear very little on pavement. They are a hard rubber compound with a very stiff sidewall. These Dessers have a softer sidewall but the rubber compound does not feel as soft as a Bushwheel. I don't think they will wear anything like a Bushwheel on pavement.

Good to know. The used set I've stumbled upon are the AK bush wheels variety with the extra tread; I imagine they wear a good bit faster than the goodyears even with the extra tread.

[Steve Pierce]

Bushwheels have a soft sidewall and rubber compound which is very flexible but does wear on pavement. I run Bushwheels on my Super Cub and also ran them on my Pacer. I mow two grass areas at my airport that are about 800 feet that I operate off of. I also taxi on as much of the grass as possible. As a warning I have repaired wrecked airplanes from people landing on the grass at unfamiliar airports and hitting culverts, sliding down hills etc. trying to save their Bushwheels. Bushwheels are expensive but not as expensive as those repairs to engines and airframes.

Looks like the side wall on the 20" Desser doesn't "bulge" out much towards the brakes. My brake calipers (Cleveland) look different than yours. The attached pictures show the clearance from the caliper to the tire (6.00x6) and the disc brake to the edge of the wheel hub. Just judging by your pictures, I should be OK. If not, than I have to move the bake disks out a little. My disks are Rapco 64-01900 1/4" thick.

My mechanic found a set of used Cleveland wheel hubs matching the ones I have on my Pacer. I just need to purchase matching disks and then I will be able to swap between the 20" Desser wheel set (for going West bound) and the regular 6.00x6 set with wheel pants for east Coast flying.

Here's a pic of the clearance I had with 8.50x6 Air Tracs. I have Cleveland 40-28 wheels (don't remember the brake pn right now, but it's the lower clearance discs). I wasn't comfortable with this caliper clearance so I got a set of ABI-BSK3 spacers from Airframes Alaska. Have a new set of Desser 8.50 Tundras that'll go on with these spacers when I find some time! Remember to check which pins you have (mounted on the caliper that floats thru the torque plate). Luckily I already have the long ones, so I don't need to swap these when adding the spacers.https://uploads.tapatalk-cdn.com/20190218/d50fa8cb92b769fa1201fc2b2faf2eeb.jpghttps://uploads.tapatalk-cdn.com/20190218/6e8357b24a1f8baaecb0659215eb6b2a.jpg

Robert,
Generally, the single puck setup from Cleveland needs a spacer. That will also cause a need for new AN hardware. If your brake caliper is not hitting the tires, you may be fine running them that way. 1/8” is getting pretty tight, so I would test it out on the ground a bit, and at lower pressure. If your calipers are mounted low, that will make it flex more, possibly causing rubbing.

Let me know what you think.

(Also for future searchers) When I went thru this for my Cleveland 40-28 wheels I was concerned about the bolt pattern of my 3-hole AN4 pattern matching with the Airframes 6-hole pattern. I called Airframes and they weren't 100%, but I figured I'd give it a shot. Airframes ABI-BSK3 does work with the 40-28 wheels. The Airframes spacer is drilled for a 6-hole pattern with AN4 thru bolts. This pattern matches some but not all Cleveland 3-bolt wheels, I have a buddy that tried these spacers on his Cleveland 40-59A 3-hole wheels and those actually have a different diameter for the bolt pattern than the Airframes spacer and most other Cleveland wheels. If using the spacer on a wheel with the AN5 thru bolts (like a 40-75) the spacer holes must be upsized by the installer. In all reality it would extremely simple to CAD up a spacer if you have a different bolt pattern and get them cut on a waterjet (I have the files for the 40-59A spacer if anybody needs them, my buddy who did this first sent them to me in case the Airframes spacers didn't fit my wheels). Also, Airframes does carry the longer brake anchor bolts (torque plate guide pins) - both flanged an unflanged dependent on your caliper type.

[Spdcrazy]

Kevbot, I was wondering if a spacer could be machined. It's not rocket science. But how does that work with FAA-PMA stuff?

I don't remember the specifics from my A&P. Could be AC 23-27 substitution of parts on aging aircraft. For reference, Cleveland did make some elongated washers (kind of a small arc portion of the thru-bolt pattern) that they used for this same situation to space out the brake disc, I think they're 095-00800. My buddy who made his own used them for an experimental Cub.

[Spdcrazy]

Had to order the wheel spacers from Airframe Alaska. For future people. It comes with four spacers (2 per side if you need that much) each spacer is 1/8" thick. Also comes with new longer AN bolts to replace the originals. I used both spacers to gain 1/4".

I test fitted the 8.50X6 22" Desser tires on the Pacer. I have double puck brakes and the clearance of the caliper (with pretty much new brake pads) is only 3/32" to 1/8". Next I need to figure out what kind of brake anchor bolts I have and then most likely will order the spacers and anchor bolts from Airframes Alaska. Just hurts that the anchor bolts are $67 a piece.

[Pacer42Z]

I worked on the installation of the 8.50x6 22" Desser tires yesterday. I use 1/4" spacers from Airframe Alaska to provide enough clearance between the tires and the double puck Cleveland brake calipers. I need to install the longer anchor bolts, but two issues. The old anchor bolts will not move out. I took the nuts off and tapped on the bolts, but they don't move. Before I apply force I thought I better ask. Are they pressed in, screwed in or are mine just "frozen" after all these years?

The second issue is, the shaft of the new anchor bolts are the same diameter as the old ones, so they fit the brake calipers. However, the old anchor bolts have a larger thread vs. the new ones. Can I still use the new anchor bolts?

Any advise is appreciated. I finally want to get these tires on my Pacer.

Juergen
Pacer N3342Z

[Steve Pierce]

I would start soaking those pins in penetrant. Looks like to me the holes in the calipers will be to large for those pins.

[Pacer42Z]

Steve, thanks for the quick reply, so I take it that my anchor bolts are "just frozen" in the calipers. I will use some penetrant and see if I can get them out. The shaft diameter of the new bolts are the same as the old ones, so they fit the anchor plates, it is just that the thread size to hold the anchor bolts in place is different. I will talk to my mechanic if I can use a washer. There is not much load on the threads to keep the anchor bolts in place. I hope it will work out.

Juergen
Pacer N3342Z

[Steve Pierce]

I would use penetrant and a socket with C clamp to press them out.

[Pacer42Z]

I did get the anchor bolt out of the caliper using Steve's advise (penetrant and a C-Clamp). However, the anchor bolts I purchased (ABI-69-01900) from Airframes Alaska will not work. I called them and talked to Chris (very nice guy and very helpful). He went out and measured their ABI 30-60A Brake anchor bolts which are the same type as they are on my Pacer, and they are 1/4" longer than what I have. 1" shaft length vs. 3/4", exactly the 1/4" I was looking for to compensate for the spacers. Bingo, a credit card transaction later and they are on their way. Hopefully this weekend I get the wheels mounted.

Finally finished the project today. By using the brake disc spacers ABI-BSK3 and Brake anchor bolts ABI-69-02600 (30-60A) from Airframes Alaska I was able to get the clearance on the brake calipers to avoid rubbing. I now have a set of 6.00X6 tires on wheels I can use with my wheel pants to fly around the East Coast and a set of wheels with the 8.50X6 Desser 22" to fly out West and to Alaska. On the first short flight I noticed about a 4 kts. loss in true airspeed, but I need to test that more in later flights. The landings felt very nice with these tires. It almost felt like landing on a pillow (maybe I was lucky the first two times).

My first mission for the new tires will be in October to attend the High Sierra Fly-in. It's about 2,000 miles each way. I'll stop in Utah on the way out for a couple of days to fly some Canyons. Can't wait!!!

The subject of speed loss when installing larger tires always comes up. I went from 6.00x6 with Wheel Pants to 8.50x6 22" Desser tires. One part of my goal was not to lose too much speed since all the good mountain and canyon flying is a good 2,000 miles from the East coast.
With the wheel pants on I usually see about 119 kts true airspeed. On several test flights (I haven't gone up to my long range cruising altitude between 8K and 12K feet yet) with the 22" tires I see about 114 kts true airspeed. So I lost about 5 kts.

[akflyer]

If you are going to play in the gravel and off airport the speed loss is worth the swap to 31s. When I bought the pacer it was on 26 GY and the 2 yr old borer prop looked like it was 50 yrs old. The extra clearance with the 31s will help you save your prop and the GY suck on anything but pavement. I had the 850 dessers on my Avid and they worked OK but I would not be happy with them on my pacer. Anyting that you have to run that much PSI in just transferes so much shock to the airframe in the rough stuff that its scary at times. I fought the BW urge for years before caving in and getting a used set. When my brother flew it with the BW on it he was kicking himself in the butt for not putting them on it when he had it. I will be pretty shocked if summer rolls around and he doesn't have a set on his 170B.

I fly my 8.50 desser tires only when I go out West (below are pics from Mexican Mountain and Hidden Splendor in Utah). When I fly around the East coast I use 6.00x6 because the soft 8.50s wear out very quickly on pavement and are about $350 a tire. I am really thinking about using 26" tires after I wear out the 8.50s, but there is a large difference in cost. Last time I checked 26" tires are about $1,400 per tire. For the kind of flying I do I can't justify the cost of larger tires.

I recently purchased my third set of 29 inch Bushwheels this time with the extra rubber layer. I also bought new ABW wheels and brakes. But, after investing ...well...a lot.... I decided to order 26 inch Goodyear's and mount them on my old wheels. I figured I would save my BW's for summer backcountry flying, I don't get to land on grass in the winter. It rains a bit in the NW. After a few modifications and a lot of messing around I finally got the GY's mounted. Today I tested them, Wow! Landing on GY's compared to BW's is ..... well....different. I've been on BW's for a few years. I had GY's long in the past. This sudden switch was a surprise. The GY's are hard like I remembered but, they make a lot of screeching noise touching down. Gotta practice and figure it out.

I find that I can judge my landing smoothness by how long they make noise. Grease it on there and they’ll kind of chuuffff up to speed.

Not great technique for backcountry stuff but it helps my wife enjoy flying around with me.

Interesting how a change in tires can effect landings. I'll see how tomorrow goes.

I’ve got a set of 31s I’ve been meaning to mount - just have to buy hardware for the wheels. I’m interested to see what they feel like!

Bushwheels make your feet lazy. 8) My youngest brother had been flying his Cub on Bushwheels a lot and we jumped in the Clipper. He was on short final and was coming in crooked. At the last minute I kicked the nose straight and we rolled down the runway. He is a real smart aleck and said "what did you do that for?" I replied "Cause you are in a Clipper on small tires and you are going to go the direction the nose is pointed." His reply was "Oh yea."

I think you're right about BW's creating lazy feet. I've been on BW's for five years, now I'm trying out GY's for my winter pavement flying. I'm still getting a chrip or two when I land, unlike the BW's. But, the chirp(s) are decreasing. I'm learning. I have 12 psi, maybe I'll try lower pressure tomorrow. No many people in the sky these days.

[CamTom12]

I run mine between 12-15 psi, but mostly so it’s easier to push out of the hangar. I have had them as low as 8 on accident but luckily no issues.

I’ve heard of them spinning on the wheel at low pressure, but no experience with it.

Finally finished the project today. By using the brake disc spacers ABI-BSK3 and Brake anchor bolts ABI-69-02600 (30-60A) from Airframes Alaska I was able to get the clearance on the brake calipers to avoid rubbing. I now have a set of 6.00X6 tires on wheels I can use with my wheel pants to fly around the East Coast and a set of wheels with the 8.50X6 Desser 22" to fly out West and to Alaska. On the first short flight I noticed about a 4 kts. loss in true airspeed, but I need to test that more in later flights. The landings felt very nice with these tires. It almost felt like landing on a pillow (maybe I was lucky the first two times).

My first mission for the new tires will be in October to attend the High Sierra Fly-in. It's about 2,000 miles each way. I'll stop in Utah on the way out for a couple of days to fly some Canyons. Can't wait!!!

How high do the 850-6 AERO CLASSIC SMOOTH TUNDRA
raise the plane compared to the 600x6 tires? What's the difference in outside diameter, does not look like they raise the axle more than an inch or so?

edit, found some info on Goodyear tires https://www.aps-aviation.com/wp-content/uploads/goodyear-aircarft-tire-data.pdf

600x6 are 17.5" tall, and the aero classic are 22" tall, 4.5" inch diff, so 2.25" raise in axle height, do they give you that much height?

[Pacer42Z]

I measured the height of the axle today. The 6.00 tires center is about 7 3/4" (with the load of the Pacer on them) while the 22" Desser are 10 5/8" without any load on them. Not sure how much that will raise the nose, but I remember noticing quite a difference when taxiing.
