I was wondering what is offset on rims? I found a set of 35's( 17" XD Spy Black Wheels General Grabber Red Letter Tire)with rims and they ask if i want a 17x8 with a off set of -12 or 17x9 with a off set of +18. What dose this mean and which way should i go

 

Offset is the difference between the vertical centerline of the wheel and the mounting surface. Negative offset pushes the wheel out, positive brings it in. I have a set of Dick Cepek 17x9 DC-1s with a -12 mm offset. The tires (285/70s) stick out about 1" from the fender.

The +18 might cause some clearance issues with the suspension. This may help you figure out what you want:

Yes it does thank u. So the negative is the best way then

 

Not necessarily. Depends on what look you want and various clearance issues. Remember, as you change the wheel relative to the hub, you're changing the loads on the suspension.
