If you bought the car with your own money, get rid of it and get a truck or Jeep. If not, wait until you can afford your own vehicle and get what you want.
FWD sedan and rough terrain don't go well together. If you are serious about going through with it, convert to AWD and get lift up the frame.

If you want some thing like a truck and can do what ever you want to do with the car but can keep from driving it hard off road. You could try some thing i wanted to do if i hav the chance to be the first. Have the back cut outand add rollbars to add support. then have a rear window placed and fitted behind the front row. SO you can Make a BonnE Camino ofcorse the back door will need to be removed and some aditional work will need to be done and the back of the trunk could be modded to be a tail gate.

If i did this it would be great fro loading and unloading my scuba equipment.

The foot area in the back seet could be used for a sub or some protected storage.

For the sake of the car, don't do it. Simply slapping off-roading tires on your car is not going to help. You will just end up screwing up your trim, getting things dented, getting stuck, and ruining your suspension. I can't see your transmission lasting very long either.

It is a sedan, not a truck. If you want to ruin a car go find something else. If you do decide to go ahead with this, make sure to take pictures.

Polishing a turd? I can't even begin to explain how incorrect that statement is...

haha its already beat up with dents and stuff i don care about that, i mean look at the pics of it it'* a pos

so explain this 'terd'' statement again for me...

Polishing a turd?! Nice quote from the movie Christine there. WRONG place to post it.

Well I'm glad we were able to find out where you get your ignorance from.

As far as putting larger tires and wheels on any vehicle, it puts added strain on the suspension, drivetrain, etc. Even heavy duty vehicle with truck suspension (EG: Hummer, GMC, etc.) can be damaged by the larger wheel tire setup. IMHO your tranny will be the first to go if you do anything to greatly increase your wheel circumference, threreby ending your cars "rough" life. If you're gonna do it, don't spend extra money on extras until you work out your off-roading bug. Best of luck to you though. I think it would be pretty cool.
