wheel modification question

[sharp67]

I have some rear wheels and the offset will not allow me to run 275s. The outer edge of the wheel sits just a bit to far out from the axle. I was thinking of having 1/2" milled off the wheel mounting surface so the wheel will sit in towards the axle. Is this safe to do? will I mess with the integrity of the wheel? Thoughts and or experience here would be appreciated. Jay

It depends on the wheel, but my gut instinct tells me that this is a bad idea.

It is a very bad idea.Either find a wheel with the correct offset .And or flair your fenders. Both are a whole lot safer.than messing with your wheel. Because wheels are built within certain DOT specifications to be able to be on the road.Other wise the wheel could fail and cause a wreck .
of which could hurt you and or other people.

I would not take material off the wheel. Depending on the wheel, if you take 1/2" off the mounting surface you will take away most of the material there and seriously compromise the wheel's structural integrity. This is an accident waiting to happen. Spend the money and get correct sized wheels for the car.

I have machined wheels to change the offset. There is a standard thickness for aluminum wheels...... .400" maybe......but those were set up for a mag shank lug nut.

I think you will find that if you milled .500" off of your wheels that there will be no seat left for the lug nut......at that point you have expensive paper weights.

Most wheels are designed to accommodate a safe load range, and the lug holes are drilled to a specific depth in order to retain the required material thickness under the lug nuts. If you mill the backside of the wheels, you remove material from a critical area of the wheel. Not recommended. Your other option is to have the rear axle narrowed, or buy wheels that fit properly.
