Seeking Tire Load Rating Experience and Impressions

So I have been running a Geolander AT+II 245/70R16 tire on my Cherokee. I have been very happy with the ride and performance of the tire but it is time to replace them and I am adding an extra inch of lift to my Jeep and I want to step up to a 245/75R16, essentially a step from a 30 to 31 inch tire. Well they no longer make the AT+II and Yoko has a new model out called the A/T-S. I like the new style tire but I am finding that this tire as well as many other tires in this size only come in an E load rating. There are some A/Ts that come in various load ratings but they all have pretty shallow tread depths at 12 or 13/32nds as opposed to 16 or 17/32nds of the E load rated tires.

So I know a lot of you are running flotation sizes with C and D load ratings but I am wondering if anyone has gone from a P metric (passenger) rated tire to an E rated light truck tire on their Jeep, or pickup or other vehicle and what your impression of the difference in ride has been?

Is an E load rated tire gonna ride a lot rougher than a passenger or C or D load rating or will they be comparable if I running them at a lower pressure?

Or would a higher load rating with stiffer sidewalls be better for me regardless because in a lifted vehicle the center gravity is higher which puts great lateral stress on the tires while cornering?

I know the stock Rubicon 245/75R16 Goodyear MT/Rs are E load rated so I guess anyones impression of the ride on these would be helpful as well?

I appreciate anyones experience with different load ratings in regards to perfomance and ride.
Thanks

Good points and suggestions, thanks.

I considered the the terragrapplers but your size is the smallest they make and I don't think they will fit on my Cherokee with 3" of lift, at least not the way I would like them too.

Point about airing down is a good one but I am not too worried about that because I don't air down much. The prospect of better handling for my aggressive driving style is a real bonus I would appreciate and I am starting to think if I run them at a slightly lower pressure than my current tires the ride harshness will be virtually unchanged, and you are right, it is a Jeep not a Cadillac.

I figured the harder construction might make them a bit more noisy, but I am happy with the current A/T+II now and the A/T-S is supposed to be quieter so I assume the trade off of higher load rating and better design will make them very similar in noise level, I hope, to my current tires. I would hope the wear characteristics wouldn't be too different from my current tire for an all terrain that spends most of its life on the street in a well balanced, well aligned form.

Kevin - Would you mind emailing me a couple side profile pic's of your rig so I could see what your tires look like with that setup.
You could post them to this thread if you know how to do that or email them to me directly at szych@infocon.com. Thanks!
