2008 Acclaim Tire rubbing

[Aspen2013]

The tire is rubbing on the inner gear door (you can barely see the shiny area on the gear door)  I just noticed this. Never have seen this before. It appears that there is plenty of clearance from the inner gear door. Its happening to both sides. I usually tap the brakes before retracting gear after takeoff. I follow gear extension/retraction speeds. Thought maybe air is pushing the gear door toward tire during landing?? Has anyone seen this before?

Are your brake lines rubbing on it?

[Aspen2013]

No just the shiny area on the inner gear door. About the closet part to the tire.

Get a GoPro camera or cheap knockoff, mount it on the tie down or sticky mount to underside of wing, take a couple of laps around the pattern, review video. It should answer your questions.

Can also try mounting on tail tie down.

Check how many washers are present between the inside of the gear door and the lower part of the strut (circled in blue).  Typically - depending on how the doors are rigged when the airplane is on jacks - there are usually between 3 and 5 washers present here to provide adequate spacing.  My guess is that your doors are fitting too tight against the bottom of the aircraft when the airplane is jacked up and the gear is retracted.  Ask your A&P to check this fit, and add washers (AN960-416) as needed.  Keep in mind that each side may require a different number of washers, as the fit may be different between the left and right doors.

landing firmly, and with under-inflated tires, causes the tire to bulge outward and contact the door. When a tire squishes upon landing, the resulting bulge does not instantly disappear. It travels as the tire rotates.

[RLCarter]

Have you recently had any work done on the doors or wheels?

[Aspen2013]

Since it just started that may be a great first step is checking air pressure. If that bulge travels around before it dissipates it wouldn’t take much of a bulge to close that gap.

You want to be checking your tire pressures regularly.

 

[Aspen2013]

I do check tire pressures regularly (Qtrly) especially as temps decrease in winter and add a little air.  They checked in today at 38 psi left and 40 right. Brought them back up to 42 psi. flew again and no difference.  Put a little white grease so I can see if it rubbed. Next I will pull it around on the ground with tug and see if it is on the ground type thing or after wheels leave the ground.

Looks awfully close...

If tire pressure is making them rub...

Compare to any other Mooney around...

 

Now I have to wonder if mine does the same thing, without me noticing...  

See if @M20Doc has some guidance on the normal distance between the tire and gear door...

Expect rubbing is not a good thing as that would also damage a tire...

Best regards,

Others are already on to the items I’d be reviewing.  Tire pressure and mis adjusted doors.

Quarterly is not often enough

 

[N201MKTurbo]

I check the pressure before every flight. I just look at the tire. I can tell you the pressure +- 2 PSI. If it is low I plug in the compressor and air them up.

[Aspen2013]

Well hopefully everyone does a visual. They might not get within 2 psi. That’s pretty good. I definitely can tell when low. Helped a buddy out today who has Cessna and he had been missing a low tire on preflight. Asked him what he thought. I guess he said maybe a little low. It turned out to be 16 psi! Not sure everyone can tell ?  If you get a good sight picture of normal then it becomes easier. 

[ArtVandelay]

If you move the plane without a tug, you’ll know when tire pressures are low.

Standard tubes need air monthly or more often. I switched to Michelin Airstops and they only need 1 - 2 psi every few months.

Agree.  My experience as well .

Yep, me three. Great product, except the tubes cost as much as the tires!

The rubbing is only going to occur with a combination of low tire pressure and a firm landing. Or normal tire pressure, and an aircraft carrier arrival...

A greely hole punch will make your current ones work.

[OR75]

the fairing looks way too close to the tire. may want to the check washers and if it was installed correctly

Needs to be fixed  

[Aspen2013]

Tire pressure not low. Exactly 42psi. No carrier style landings. That last landing was a greaser. Not saying they all are but that one was. Going to check washers. Probably be jacking it up soon.
