Hers mine I leveled my truck with Bilstein 5100 ride height adjustable struts on the highest setting 1.77. Put on some Fuel Maverick D538 +1 offset wrapped in 305/55/20 Mickey Thompson ATZ P3's , and did a Small Nor Cal Fender Mod. Let me say that these tires would have rubbed on both the front and back wheel well liners and on the front/rear metal with out modifications. I was very uneasy about cutting into the metal framing and taking a hammer to my truck but after reading some post I went for it. It was supper easy and only took about 2 1/2 hours start to finish. I used some rustoleum on the part of exposed metal before I put the liner back. I actually did the fender mod before I put the tires on because I knew it would rub pretty bad, but after the mod you can not tell at all. On the front wheel well liner I drilled two holes and used some washers for extra support then used tie wraps to pull the fender back so it will not rub. After these mods I don't rub anywhere. Not on the sway bars either.

Wheel Offset

Refers to how your car’s or truck’s wheels and tires are mounted and sit in the wheel wells.

– Zero wheel offset is when the hub mounting surface is in line with the centerline of the wheel.
– Positive wheel offset is when the hub mounting surface is in front (more toward the street side) of the centerline of the wheel. Most wheels on front-wheel drive cars and newer rear-drive vehicles have positive offset.
– Negative offset is when the hub mounting surface is behind the wheel centerline. “Deep dish” wheels are typically a negative offset.
