Harsh ride and probaly main reason is I bough it without her council !:toilet3:
You should have the suspension checked.
I bought a used 08 Limited V8, and it rode horribly.
It turned out I had a fancy toyota suspension called "xreas", and the
shocks were leaking.
It's super expensive to replace with the factory shocks, so many people
just remove the whole system and go with aftermarket shocks and upgraded
springs.
Once I made the change, the ride difference was HUGE. I also put on polyurethane sway bar links, replaced the sway bar end links that were worn out (bought some made by [MENTION=98153]MStudt[/MENTION] ( and replaced the tires with Michellin Mud and Snow rated tires (but I kept the 18" wheels), because the tire I got are more for on-road driving with occasional, light off-roading, as opposed to some of the more aggressive tread designs on more off-road oriented tires.
As an FYI, I went with Bilstein 5100 shocks ($350 delivered from one of the forum vendors), and found some used toyota springs from an FJ cruiser.
There's a whole, very long thread on this upgrade.

My point is, make sure that the problem isn't the suspension before you start changing your rims and tires.
If you want more info, lemme know and I can refer you to some more helpful threads.
