Good tires (Michelin/Goodyear), properly installed with Michelin Air stop tubes, air pressure >35 psi will eliminate 99% of flats.
Every flat I've ever fixed (many) would not have happened if the above was religiously followed.
Stop being lazy and check the air pressure at least every 90 days.

I've heard a lot about how time-consuming it is to check tire pressure on the RV-10. Big wheel pants, lots of screws, etc, etc. With appropriately-located holes in the pants and brackets, it takes about 5 second per wheel to check the tire pressure, and only slightly longer to add air if needed.

Pants stay on unless you just have to have a look at other things while you're there.

No, they're 90 degree angle stems. Leak-stops form Desser, if memory serves.

I have not seen goat heads but I have had to dodge deer, coyotes, golf carts, and a bum pushing an old shopping buggy.

Goat heads are a small round thorn found in AZ. They destroy tires.

I've never had a flat (knock on wood) in 1600+ hrs on my RV-6 and I've landed on some rough places. Though I can't say I've been to any that were littered with goat heads
Michelin Air Stop tubes, Condor tires. I always replace the tubes when changing tires although I'm reconsidering that based on some other threads on the topic. I don't have those links but the gist is, ample evidence that if cared for properly and inspected for chafing / wear good tubes should last through many tire changes.

I would say:

1.) Low tire pressures allowing scrubbing tire casing on inner tubes and even shearing valve stems in extreme cases. I like to keep mains at 50psi minimum and while on the high side that works great. As a diametrically opposed aside, I keep my 31" Alaska Bushwheels on my Husky at 6 PSI. But they are tubeless and the valve stems are built into the side walls and cannot be sheared.

2.) Pinching tubes during installation. Use lots of talc powder (real talcum only). I rub it inside the tire casing and all over the tube. Then after inserting the tube into tire I remove valve stem and inflate tube a couple to times lightly to round it out and give it form. With valve stem removed the pressure inside the tube will be equal to ambient pressure. Don't re-install the stem until the wheel is completely assembled. This process keeps the tube from being pinched by the wheel halves.

3.) Avoid Leak Guard brand Butyl tubes as we have seen them come apart easily at the mold line seams around the tube. Especially if combined with too low operating pressure as mentioned in (1) above. To give them credit, they don't leak as advertised. They just pop all at once. If you do use Leak Guards use more talc powder than usual during installation and run on the high side of pressures. The extra talc will help mitigate scrubbing of the mold lines on the inside of the tire casing. Michelin Air Stops also made out of Butyl don't seem to have this same problem as the Leak Guards.

4.) I live in goat head central, but I have only had goat heads flatten the smooth tundra type tires Desser sells where they grind off the tread so they look cool (smooth). There is so little thickness left on the tire a single goat head will take them down. Not a good attribute for a tire advertised for off-airport use and they now occupy a shelf in the hangar. But I haven't seen goat heads cause flats in the typical 5.00 size tires on RV's...... Yet.

Yep...only flat I ever had was caused by this.
