Ride Comparison between 265/70 C-load vs. 255/80 E-load

Hypothetically if comparing two same make and model tires, but one is 265/70/17 C-load and the other is 255/80/17 E-load, how would the ride quality be on-road between the two? I see some mixed reviews about ride quality when I search around the internet, but I thought I would ask here too. I don't want to jeopardize highway driving comfort by going to an E-load unless the differences are negligible. From what I can tell, it also depends on the PSI ran in them so that would be important to dial in also. Off-road I know E-loads are typically much tougher so that's not a concern. I really want to step up to a 255/80/17 but am hesitant on the ride for my wife and kids. Thanks for any help!

 

What E load tire are you thinking ?

 

I'm looking at Ridge Grapplers.

 

Sweet tire! The only thing I’ve heard is 255s get stuck in the grooves the semis make, makes them feel a bit grabby.
The right tire pressure makes a difference for ride quality.
