Guys, I am a newbie in trucks and thinking about changing my tires so I thought why not changing my rims as well and go bigger.

I am thinking of getting 18" wheels with more width than the standard original tires (again excuse my newbiness) - a larger width.

1- What are tire sizes that you guys recommend for 18" wheels? something not too flashy but where the tires are coming outside a little bit more than the standard original ones.

2- Any recommendation on cheap/affordable rims / tires? I keep looking around and can't see anything less than $2000 for the 5 rims/tires. I'm a little short on money :s

thanks in advance
