Default Cooper ride?

So i just got the cooper ltz. I went a little wider with the 305.
My question is, is it normal to loose some ride quality when changing to a tire with a larger tread pattern? I previously had the stocker goodyears.
It just seems that the truck wants to wander a bit and is really bouncy over bumps.Very noticable over stock.
Now i know that the coopers are a 10 ply and E rated. I run 50psi in them, which is what was recommended, They max at like 80psi.
Any thoughts?

If you have the 20's like me they will... Mine are quite stiff.. Dosent bother me though... I might get better shocks than keeping stock ones.

The stock goodyear's are lightweight flimsy balloons with a little tread on the outside. I changed out my own and was surprised at how little material those tires had, the BFG AT's of the same size were damn near twice as heavy and a lot stiffer when stting side by side with the goodyear's off the rim. You might try to drop the pressure 5psi or so, as long as you're still getting a good contact patch you should be fine.

Any E rated tire is going to give you a harsh ride, then factor in a halfway decent block tread pattern and it will be even more so.
That's the trade-off when you put real truck tires on a truck...

You think that's bad, put you a set of E rated Boggers or Baja Claws on that sob and take it for a spin. Now THAT'S what a truck is supposed to feel like...

The LTZ's are a much more rugged tire than the stock "car"tire that comes on the Ram's. They have way more in their sidewall. Ride quality did get a bit harsh and that's the only thing I didn't care about, however, if you noticed....The LTZ's are super quiet!!!
Now, the 305's are wider. Wider tires up front tend to grab and wander a little more. Nothing unusual. It's normal. My mustang wanders a little because i put 275's up front from the stock 245's.

i just got the zeons as well. let me just say they rock in the snow! but i agree they are much stiffer going over bumps and pot holes but they bite like crazy, hard to break em loose. i have to disagree with dirtydog though, the ltz are louder then the stockers, once you get on the highway they have a noticeable whine to them, but other then that i love em.

With the 305's you now have a half-inch less sidewall for cushioning too. That plus the better sidewalls and you get a rougher ride. I run 38 psi in mine.

I don't mind the noise at all. It's just a little to remind you they're there!
