Anyone have any numbers yet on time between main tire replacement and brake lining replacement?

I made around 275 hrs. on brakes, but one pad was  just barely serviceable, wont go that long again.  My tires are still good  at 308 hrs. My new landing procedure will be to roll out more, save some  brakes.

I had the same situation on my old Maule, that is, the tires would     wear on the outside and would require flipping to get full wear.

     

     I assumed it was because when the gear was unloaded, the gear legs     would swing inward somewhat.  On landing, the outside of tires would     contact the runway first.  That's when then would spin up from 0 to     50, and it's also when any misalignment would be 'scrubbed off'.  I     figured it was when the most wear was put on the tires.

     

     Is this what may be happening with our '10s?

     

     BTW, thanks for the maintenance profile question and the feedback -     good stuff.

For what it's worth, time between replacements on things like tires and brakes are going to depend a lot on what kind of flying you do.  Lots of landings equals wear and tear on the tires and brakes, in addition to technique, rather than time.  My tires started lasting a LOT longer once my flights were more of the 4 hour type than beating up the landing pattern.  My point is simply this sort of data is going to vary a lot between users so may not be of as much help as number of landings, which most folks don't track in their maintenance logs.  Having said that, it still might be useful as most of us use the airplane for cross-country so the info might be more consistent after all.  Time for more coffee, that was a lot of rambling, sorry.

My RV-4 does the same thing, as did my Cessna 140.  This is simply a characteristic of spring type landing gear.  They are designed for the wheels to have proper camber when carrying the weight of the airplane.  As Bill pointed out, the maximum wear occurs when they are pretty much unloaded.  If the gear were designed for the tires to touch down level, when the gear was loaded with the airplane’s weight they would be wrong and the plane would be difficult to control on the ground.    

   

If you want to have it both ways, you need gear like my Pietenpol has:

Jack...Gorgeous airplane!  Looks like a lot of fun.  I've been toying with doing something like that as well for just buzzing around which the -10 has proven to be a bit expensive for thanks to current gas prices.

Here were my numbers on the stock tires and brake pads. Like others have said, I am getting better wear now that I have more time on the plane.  With Dresser re-treads, they will last much longer than the stock tires from Vans.

So....is anyone removing their tires before the wear is too extreme, and flipping them 180 degrees? Or keeping the orientation the same and moving from left to right side? So the worn part is now on the inside.

Definitely. It always wear on the outboard side of the tire, so you get almost double life if you flip them.

I wait until there is no groove on the outside

tread groove...then flip it on the rim and use the

other side of the tire.  Even when there's a lot of

wear there, it works out ok because you just don't

use the inside of the tire much at all.

Flipped them at inspection time - about 80 hrs. Appreciably more wear on outside.

Just flipped mine at first annual, after 171 landings.  Still had some good tread on them, but decided to do it while I had it down for annual.  Almost zero wear on the other side of the tires.
