I have an 01 Tahoe LT 4X4 and the tires are just about ready to be replaced. I figured that while I am at it I could use some new wheels as well.

I already know that I want to go with BFG M/S, but my problem came when I was looking for wheels.
I contacted a rep from OutlawOffroad here in Orange County and he directed me to Eagle and Pro-Comp.
I think he works on commission so I wanted to get some straight advice from non-biased people.

First
My truck is stock height, but I am looking to get a more aggressive stance by using slightly wider wheels than stock, maybe 8 or 9 inches instead of the factory 7. Is this possible or is it going to rub and drive me nuts?

Second
I was looking at the Eagle 058 series and the 186. Is Eagle a reputable company? I mainly use my truck for snowboarding trips and the occasional towing of boats and jet-skis.

Finally
The quote I was given
$440 for the wheels (Eagle 058)
$830 for the tires (BFG 265-75-16 AT)

Am I being taken advantage of, or does this seem like legit pricing?

Thanks for any help you can give me. I tried searching but I guess the 4X4 section of this site is relatively new and I didn't come up with many answers.
Take care guys.
