Wheelpants vs. 8.00 tires and naked

[blueldr]

That N9125 sure is a beautiful airplane. The owner should be very proud.

But Geeze, the wing sure is flat, isn't it?

this has probably been in a prior post,
but what does it take to convert to these bigger tires?
thanks

The Type certificate approves three different tire sizes on the original wheels: 6.00 X 6 (4 ply), 7.00 X 6 (4 ply), 8.00 X 6 (4 ply). So as the pilot/owner you may simply change them out amongst these three choices.

(Chances are tho'...you do not have original Goodyear wheels. heh-heh.)

6:00, 7:00 and 8:00 series tires are on the type certificate so it's a maintenance item that the owner pilot can perform.

As you might have read some folks have brake clearance issues with 8:00 tires. I've had 2 different types of 8:00 tires on my plane with no problems. If you have a clearance problem that needs modification you r moving out of the owner pilot maintenance category.

Any size tires other than I listed such as 8:50 tires would require some sort of approval.

George we need to stop typing the same thing at the same time.

I was two minutes ahead of you. (You got "loquacious".)

That's a classic STRAIGHT wing Dick!

Also, that wing is for pilots who have the ability to land in short places with small flaps. All others should restrict themesevles to the B model with the bent wings.

Hey George I had to upload that clip again as I'd removed it to make room for other stuff.

Sure was cool looking at it again though. Just so happens I did one just as short today but I cheated with a 13 gust to 19 knot head wind 20 degrees off runway heading.

george
when you say change them out
does this mean that the rubber
fits on the same rim,
or the 8" rims fit on the same axle?

[GAHorn]

8.00 X 6 tires fit on the same wheels as 6.00 X 6 tires. The last "6" is the inner diameter of the tire at the bead.

[iowa]

you can see that i am profoundly ignorant about certain things!
but i think i follow you.
so the 8" have the same ID but the OD is much bigger!
are the 8" tires wider?

Gotta ask this "splitting hair" question Most all of us (those of us w/o A&P license) have replaced tires on our planes, cleaned, inspected & repacked the wheel bearings & reinstalled the tire/wheel combination. While I think it is within the rules for owners to do so (without AI approval), isn't it an unapproved act to remove the brake pad on the outer side of the disk which allows the tire/wheel to be removed? Seems I read somewhere that anything to do with the brakes required a signoff of an AI & removing the outer pad is monkeying with the brakes. Sure would be a b---- to deflate the tire, remove the bolts. & mount a new tire & tube with the wheel still on the axel

FAR part 43, appendix A (c) defines preventive maintenace, which includes "(1) removal, installation, and repair of landing gear tires," and "provided it does not involve complex assemly operations."

As long as removing the stationary brake pads is not a "complex assembly operation," an owner/pilot is allowed to perform the work and log it.

That's the way I read the FARs, anyway.

Thanks John.
