FYI Beringer dual caliper brakes on a CubCrafters Carbon Cub

Whey they chose 29's if beyond me.

Perhaps because it was a compromise between 26 and 31. I would never put 31 inch Bushwheels on my FX-3. I simply don't plan to go anywhere I would need them and there are too many disadvantages.

Perhaps I go to less hostile places than those who chose 31 inch tires. My 26 inch tires with Grove 1.5 inch calipers are a perfect match on my FX-3. I have done nothing to them except top of the reservoirs in over 500 hours. 46% of my nearly 700 FX-3 landings were not on paved runways and I have to land on a paved runway to get back to my hangar.

Not criticizing those who choose 31 or even 35 tires. Just a caution to those who may be deciding on large tires for the wrong reasons.

It's off topic but I'll share why I chose 31's. As I'm stuck on on asphalt I wanted max circumference for tire wear. The cost difference is minimal from 29's which CubCrafters now requires for the 83" prop. We all know they used 26's early on. So when it comes to 29 vs 31 and only a few hundred more for seemingly a lot more tread area I chose 31's. Obviously with off airport and ruts, etc. larger is just safety margin. Here in VA where it's a lot or tall grass you can't see the trenches.
