My truck is an 07 Sierra Classic CC 2wd. I will be running 17x8.5 welds w/ 4 5/8 bs. Could I fit 285/70r17 street tires w/ coil spacers?

I guess I will need to go with a 3" lift then? How much will this increase the front track width?

If you do a 3" or 4" spindle, it will widen the front about 1.5-2" per side. So 3-4" total.

If you do a spacer, it won't widen it at all. They don't come in 3" though... only 1.25" and 2.5" I believe. (And then the springs will sag a little too, so subract another 1/2" to 1" off of those numbers.)

A 3" body lift would work too.

BTW, does your '07 have coils or torsion bars?
