337 done. tires installed. In order to complete the 337, I have to taxi left and right with alternating low pressures on each tire and then fly it, followed by a log book entry.

I'm looking for recommendations on the highest and lowest pressures you have run on these tires.

That is a very nice looking aeroplane:)

What he said...... Nice bird!

On a 170 I've run them as low as 6~8 psi, but 10~12 psi is a more reasonable lower end. I've never put more than 20 psi in them for the high end, but I'm sure you could pump them up higher if you wanted to.

Day to day I run them around 13~15 psi, which makes it easy to push the airplane around but still gives some cushion. At that pressure there's a bit of a flat spot where the tire rests on the ground, but not as flat as it could be. At 10 psi it's noticeably harder to move the airplane in and out of the hangar.

I glue the tires to the rims, and I mean really glue them on good...cleaning the tire and rim with solvent and then using a generous coating of Barge Cement all the way around both sides of the wheel and tire, and I paint tattle marks to show any creep. I've never had any movement at all. I've also never skidded a tire on hot pavement at 6 psi, so I'm not saying that they couldn't move under the right conditions.

With a heavier airplane I assume you'd want to run them a couple psi higher than I normally do.

I don't expect them to perform like bushwheels, but I like them. They're a fraction of the cost, last much longer, and give a lot of insurance against that unseen badger hole or soft spot on landing sites that should have been ok for regular gear... They also don't throw rocks up like a treaded tire does, which is very valuable.

All,

She's pretty alright. Fly's as good as she looks too.......

Hammer....thanks for the info. I did not glue mine on, but given the heavier 180, I'm thinking around 15-18 psi. Agree with your reasoning on these tires. They fit my mission profile perfectly and definitely pass the eye test. Can't wait to fly with them.

20# with no screws or glue.

Now you just have to go someplace instead of being a "no show" and staying home.

For the last time..............I was killing a Bear!!!!!

Is the taxi requirement (to complete the 337) unique to the Goodyear 26s?

I've seen a 185 spin them on the rims with 15psi with heavy braking. I also know of another guy who runs them basically flat, and just doesn't use the brakes much.

I have screws, and can go as low as I like, they don't move.

That's what the mechanic told me too.

That is a beautiful airplane, by the way.

I use 18 PSI, any lower and they will slip. I tried glue but it made no difference, I may not have used enough.
I love my GY 26's, best value for money out there if you use asphalt a fair amount.

yes the taxi exercise was a requirement for the 337. They wanted to make sure there was no rub on the brake calipers. They also required a solo flight followed by a log book entry.

20 lbs it is......
