We’re often asked if running a negative offset will come with problems. Here’s my opinion on the topic, If the offset is too negative and you’re running an oversized tire, I’d say you have a high chance of encountering problems.
When your vehicle was manufactured the suspension components, hub and bearings were all made to specifically tolerate your original equipment wheel and tire weight and overall geometry. These components do offer a little tolerance for plus sizing however not when it’s an extreme.
So let’s say your truck comes with a 31 inch tire from factory and you lift the truck and jump up to a 35 inch tire. The tire is going to weigh more than your factory tires. This upgrade will cause some strain to the drivetrain which can be resolved by regearing your ring and pinion but not always is that required.
When can problems arise from a negative offset?
Let’s say you now take that already borderline fitment and use a super low offset to hang it out the fender. You’re now increasing the overall strain as your vehicles hub and wheel bearings will suffer being that the wheel and tire geometry has now changed and your factory hub and wheel bearings weren’t designed to support the additional weight.
Think of it like this, if you hold an apple in your hand and close to your body you can do so for an extended period of time with minimal strain, now imagine holding a watermelon with one hand with your arm fully extended horizontally to your side.
You can definitely plus size your wheels and tires to where they can hang outside your fenders safely with minimal strain but there is a very fine line to those limitations and we always recommend that you consult with an expert to determine what that fine line is.
