When I first bought my truck I ordered pro comp wheels in 17x8 with a 4.5 backspacing and I'm regretting not getting the 17x9 size now. The tires barely sit flush with the fenders. Has anyone used spidertrax or any wheel spacers for that matter with aftermarket wheels? If so, please enlighten me with with your specs, experience so far, and pics if you have them. My consideration for wheel spacers is purely cosmetic.
