how can i get some 17's with tires cheap under 900 dollars?

 

Anything in particular. My suggestions:

1. Check some local salvage yards.
2. Check some wheel manafacturers web sites. For example, Centerline (if you care for thier styling) has usually got a decent selection of 17 inch wheels in the clearance section of thier site. The first set of aftermarket rims I ever got for my 17 were Ronals for less than 400 dollars shipped, directly from them.
3. Keep an eye for a deal in the for sale forum here or other boards focused on the 4th gen f-body.
4. Afswheels on eBay. Link. Sometimes you can catch them just right and get even cheaper prices than their already ridiculously low prices on rims. I got a set of ZR1's off of eBay from them for less than 500 dollars shipped recently.

 

As far as tires, just check some online vendors or locally with someone that sells used tires if you're really that strapped for cash. What wheels and tires do you have now? It really would be helpful if you were more specific than 17's in what you are wanting.

 

I got eagles 17's right now. My friend wants to buy them. So I might get around 600, and I want some more 17's anything around 600-800?

 

Also theeagles are 17x8 i think. So if I get the 17x9.5 and 17 x 11, how much added weught will that be i wondor? if I got a 17x11 will a 335/40/17 fit on the back ok?
