I think as far as the ride, the size will be less of a difference than that of going from a passenger tire to a light truck tire. LT tires have a reinforced design with thicker sidewalls that are made to handle heavy loads and have better durability. They aren't much different than a commercial tire. They are typically quite a bit heavier than passenger tires. If you do a lot of off-road driving, especially on rocky terrain, the LT tires will be a benefit due to their heavier construction. However, if you do mostly highway driving, you will find a big difference in ride quality compared to a passenger tire.
Personally, on my '06, I noticed a big difference in ride quality just switching from Michelin LTX M/S2 tires to Nitto Dura Grapplers, which was still a passenger tire (although they do also have LT rated tires). While the Nittos have been a good tire, they definitely do ride harsher and I'll be going to either Michelin Defender LTX M/S or Kumho Crugen HT51 tires then next time around (I have stock suspension w/ Airlifts and do mostly highway driving).
