I am in the process of buying a set of 26" wheels and tires tomorrow but they have 2 different offsets which ones should I buy +18 or +30 offset? Some of you remember my old set were stolen last spring. It was +25 offset. In future I want to get my truck lowered by 2/3. I believe +18 offset is good enough for lowering my truck it won't hit the fenders or anything. Have a great weekend!!!!

That's correct if you're planning on dropping the truck I'd say go with the +18 set.
