Re: truxxx vs. daystars
This is too vague to answer correctly.
32" and 35" tires are very different first of all. If you're Ex is lifted, that's one thing, but if it's not, I wouldn't go higher than a 31.6" tire (265/70R17), or you'll get rubbing. If it's lifted at least 4", you can get away with the 35" tires, but you'll have to lower the gearing (say from 3.73 stock to a 4.56 ratio) so performance doesn't suffer, and the drive line doesn't strain. For off-roading with 35" tires, I suggest at least a 6" lift kit for better articulation.
As for the noise and vibration, it's mostly only audible at lower speeds. You may feel vibration through the steering wheel at higher speeds (65+mph), and the noise will also be bad with any off road tire.
Again, you have to be more specific, and tell us if your vehicle is stock, or has been modified to accept larger tires. Remember, bigger tires aren't always better if you don't upgrade the gears as you'll lose your low end torque and the crawl ratio will be nil.
