A few things - you are running tubeless.... right? (if not, punch yourself in the balls)
If that's still the case running tubeless, then I'd suggest either investing in Schwalbe Super gravity casing tyres, or wait for the upcoming Maxxis double down casing.
The Specilaized Grid casing Butcher is a fair bit sturdier in the sidewall than those tyres you're running, but not quite as much as the SG. There are other options too, like Onza's Ibex ... but I've forgotten which casing is the one to go for!
Continental have brought out the apex carcass, which is also very sturdy, though I've not used this myself... a mate swears by it.
Yes on the front i've had no issues, on the rear i've been running it on and off, twice i've had the tyre effectively blow off the rim under hard cornering, with tubeless, inbetween i've been running tubes but everytime i stick the tubes in i get flats, I wonder if its just the tyre rim combo, think SG might be the way to go, also plan a wheelset change in the near future when i get round to selling my DSLR that i just dont use, may have better luck with tubeless with a better tubeless specific rim, i'm running a stans kit at the moment on the standard wheelset, I'm guessing a loose fit on the rim is the reason for the tyre blowing off.
Just frustrating thats all.
I'm so tempted to try a Rock razor on the rear, but its a lot of cash if i find its just too loose for my liking.
