what is the difference in a 0 offset and a -12 offset? I just oredered tires and wheels online and just noticed they are a -12 offset. Am I in for some problems?

long storys short the wheels backspacing is tucked in the fender more....the wheels wont stickout from the fendersas much or at all with -12....alot of people throwing big tires on their lifted trucks will run something near a 0 to -3 offset to get that "mean look" i guess of the wheels poking out more....what size tires and wheels?

Mark, Go out to your truck and turn the wheel all the way to the right and left with the current tires and rims your running and note how much clearance you have now. You'll also need to know the offset of the rims you now have vs the ones you ordered. A negative offset will bring the tires further out from the fender and a positive will bring them inward. Here's a site you can use to see the difference in tire dia and widths to compare the two.

If you remove one of your stock rims a quick measurement from the seating surface to inner and outer rim edge will tell you whether they are 0 ,positive ,or negative offset.

wait...-12 means it will stick out past the fender, negative offset pushes the wheel farther out.

Short answer:
Negative offset pushes the wheel and tire out from where they bolt onto the drum.
The stock Silverado 1500 wheels have a +35 mm offset, which is why they tuck under the fender wells.
I recently installed wheels with a +12 offset, which moved the tire out about 3/4" from stock.
You can get that "agressive" look, but, be careful. In some states they either allow no tire showing or if so, they may require you to install fender flares.
Also, doing this places stress on the wheel and axle, so talk to someone before doing this.
I found great support at rimzoneonline.com
The people there are very helpful.
