The heavier the sidewall the lower the pressure you can run. And should run. You have the certificates why worry about 'heat' buildup destroying a tire, I've never heard of this happening.
30-35 psi should be tried before getting rid of them and I can guarantee you they will wear evenly, all of mine have. All ten tires I've had on my truck and 5 on my brother's have been fine.
If 30-35 psi is still too rough then at least you will know.
So you never heard about the Firestone/Explorer mishap that left a couple hundred people dead. Ford made an executive decision that to make the ride more comforting, they spec'd the pressure to be 26 psi on the oem Firestone tires instead of the 30psi that was on the tires. This combo of heat/an existing defect and low pressure caused the separation. And no, they didn't add the 3ply sidewall so that you could reduce the pressure so you could have a nice ride and protection.
To address others' comments, I'm moving back to Michigan where E load is really overkill for wheeling as there are very VERY few rocky areas in Michigan, mostly mud and sand or roots. If I were staying in AZ I might give it more consideration. I think the E is a fine tire, just not for my needs. Pointless loss of MPG and increased harshness.

I went with the C's, running at 40psi and the ride is great.
Aside:
In the week I drove with them, I noticed about a 2 mpg drop from my coopers which weighed in at 44lbs, the C's are 45lbs so I estimate that I'll get close to my mpg starting point.
