Do 10-ply "E" rated tires suck, ride-wise, or are they ok?
Yes, I prefer white letters out on a beefy sidewall as well. I went white letters out on these 305/65-18's.

thanks for the pic. I like the letters better. I called the tire shop today and they will reverse them for free. going tomorrow.
Once I stop being lazy and read the directions, I'll have to post pics
Thanks a lot fella's. I really appreciate all the feedback.
We're probably only gonna have one or two more big snowstorms this spring... then I'll need the summer rubber. Good to know the "E" load is an option.

The 315x70x17's I have are "D" rated and only 50 psi max. Hummer H2 tires and are smooth riding at 42 to 44 psi and let's me get good hwy gas mileage also. My Toyo 285x70x17 AT's are "E" rated and ride a little rougher. My new shock's helped out a lot also with the ride.
I think the problem is that you're too lazy to go out and find a C rated tire.
Calling me lazy makes me sound like an underachiever. I prefer "fat and lazy".
Hey, I just live a bit north of you. I just put on the BFG At KO's (305/65-18), I did a bunch of things at once (2.5 a/s, air bags, tires). At first it drove kind of weird but it doesn't feel any rougher, to me I think it's the bit of bump-steer caused by the levelling kit.
Conclusion
Got a PM about this thread and I figure I should post a conclusion.
I ended up buying a set of Toyo Open Country H/T LT275/70-18 tires to meet my summer trailer-towing needs.
As some people posted in this thread... the "E" rated tires aren't necessarily "rougher" but they do feel funny and you can certainly feel the cracks and joints in the road more clearly. I don't much like the feel of a concrete road.
Based on nothing more than my impressions I would guess that the "amplitude", or linear travel, of road induced suspension movement is the same or less with the bigger, heavier LT tires. But that the "frequency", or rate of change in induced movement, is higher with the stiffer sidewalls. So bumps and cracks feel small but it's like they have straight edges.
The bottom line is that, I wouldn't put LT tires on for no reason at all... but if you did have a reason to want them (be it cosmetic or performance related) I wouldn't even stop to worry about the "E" rating. I'm happy with mine.
Damn. That is a nice signature done with Corel Photo-Paint.

Thanks for posting the feedback after riding on them. I have heard 3/4 people tell me at my work not to put an E tire on my truck as they siad my mileage will go to hell. Two of them drive bowties so I didnt much listen to them anyways. Now to decide between at's & mt's.
Wish I could address the milliage issue for you. Can't.
I know I get better milliage in the summer with my heavy LT "E" rated tires than I do in the winter with my lighter P-rated snow tires.
but
in the winter we tend to idle our engines a fair bit
you know
so we don't freeze to death.
