So what is this "mod"?
Replacing the old school roller bearings in your main wheels with no fuss, never mess with, sealed bearings. Like what's currently in your nose wheel!
Here is the link of my original post back October 2013 in the modification sticky thread.

Default Wheel Weights!!!!!!

I guess I have not been paying attention, I did not know he could do the RV12 wheel. Mine are coming off and getting sent off NOW.

Default weights

Amazing number of weights. Conversely, my BMW motorcycle with metzeler tires require NO balance weights.

These are really small wheels to require that much weight. I know little about this mod other than the very real question presented in the past of how those bearings handle side loads...but I assume there is a machining done to allow the bearings to seat? Are you sure the machining is exactly centered?

Isn't there a dot on the tire to position opposite the fill valve (maybe it's WITH the fill valve. Can't remember which)? Would that result in this much balance weight if it was wrong?

Default WoW, Yea of little faith

Sorry Allen,if I inferred that you didn't take the hours involved to correct a Tire issue from a Far away exotic land.Net Net.your time&considerable skill Vs a new Michelin tire but as you stated why waist a new quality control checked tire just because it has square sides!

Allan,

The tires are original equipment and have about 90 hours on them. As you saw, the tire wear has been minimal and tread wear very even. My aircraft is about 30 pounds lighter than the standard RV-12. I had no vibration or steering issues that I was aware of.

When the time comes for tire replacement, I'll send the wheels and tires back to you for re-balance.

However, thanks for turning a sow's ear into a silk purse.

Regards,

I never waist a tire. It would be a shame and who knows, I might find my old hula hoop in the hangar. :-)
