Gulf Coast Speed Semi Wheels

Spacers between the two 22s is scary in the first place. Also no matter how big of a spacer you put in between the two wheels you cannot space them out enough for say a 305 section width tire. And if you do space it out that far then you have the same result as if you run the 4 regular 22s with the faces milled in the rear.

When someone wants to run all 4 rears with wider tires than a 265 we give them the options to mill the faces of the wheels like Drag stated above.

This is one of the downfalls of this type of wheel. It is mainly used for airride or static applications with a lo-pro(265 or smaller) 22" tire.

I'm going to be the Devil's advocate here.

Don't wheel manufacturers have to have their designs approved by like the dot?

And wouldn't milling these down make the dot mad?

I'm not saying they are not safe but lawyers don't alway look into common sense.

I have been thinking the same thing for a while now.

I hope to one day run some 24's on my dually, but say your tooddling down the hiway and have a blowout. Could have nothing to do with the wheels or anything. You wreck and kill a family in a minivan. They see you have modified wheels and bam your doing time.

Or they can look at modified suspension, frame has been cut, etc.....

Either way, we're Fd if it comes to that......

Oh I know. Just throwing it out there.

Trust me, my dad has been an owner/operator for over 30 years......I know how Fd up the law system is out on the roads today...

yea i think they would go after the suspension frame height requirements and such before even thinking of the wheels

The point of the GCS wheel is to save 2 1/2" on the outside near the fender without milling the faces. Milling the faces 3/8" to 1/2" only saves 3/4" to 1" overall like Drag says. I'm assuming Drag and Lock are milling the faces of the rear dually wheels that touch (between tires) and not the opposite faces that face out and in. If they are milling the faces that touch, then 3/4" to 1" is specifically saved on the outside near the fender lip.

My machinist and I feel that milling the faces is not such a great idea because now you have decreased the thickness of the aluminum at a critical and load bearing area. Thinner = Weaker. The hub face is only 3/4" or so to begin with. However, I've seen it done and no one seems to have problems. I'm not saying it's wrong. It's just not my first choice.

I agree that you cannot run a GCS wheel with a 295 or 305 tire. We are really interested in just running the 275/45/22 Pirelli and only using a 3/8" or 1/2" spacer. A 1/4" spacer may even be sufficient.

The DOT is messed up. There are alot of 18-wheelers and drivers that have no business on the road, yet they are out there everyday. Instead , good looking-equipment and American drivers and Owner/Operators are pulled over or inspected at weigh stations for no reason at all.

You gotta consider that those wheels are rated at around 9000lbs and a factory dually wheel is rated at only around 3600lbs. So milling some off the faces shouldnt hurt it that bad. I'd worry more about the bead being milled more than the face. My wheels were 1" thick and we took 1/2" off the face of the front ones to help tuck my lugs. 1/2" thick wheel never gave me the first problem.
