machining the escalades to fit.

how much needs to be removed from the wheel? or can the little tabs on the mazda hub be ground off without any ill effects?

great question! Im about to put some chevy 6 lugs on my Isuzu Pup. It also has those same tabs on the inside of the hub.

i ground the hubs off on my zu so i could get denali's to fit. i haven't had any problems or vibrations and i drove my truck 2000 miles across the country.

i was worried about vibrations.

I think the Isuzu has a wider set of tabs than a Mazda... and a Mazda has a wider hub center/tabs than the Escalade... your best bet is probably to grind down the tabs on your hubs because those escalades will be bored to the max once they fit on an isuzu with hub tabs!

i ground the tabs off my mazda for the eskies and drove it daily 70 miles for about 7 months with no vibration problems.

i took a 4" hole saw and put a 3" inside of it and drilled through the wheel. There was no vibrations or anything.

I took my escalade wheels to a machine shop and had the center bored to 3 3/4 inches. They fit with just a very little gap between the tabs.

escalades are made to be hub centric and not carry the weight of the truck only on the lugs.

now an escalade weighs about 3 tons and the mazda truck just over 1 1/2 ton. Plus the mazda has 6 lugs to distribute the weight, and bagged mazdas rarely carry anything whereas escalades frequently carry 5 people and tow boats.

So is it likely to fail on a mazda with ground hubs? no. I had mine machined though. The drawback to using the holesaw method is you cant have the wheels balanced on a machine any longer. The drawback to grinding hubs is you almost always gouge up the studs unless you thread a few spare lug nuts on them.

Like I said, I had mine machined.

I grinded off my hubs to bolt on my new chrome eskies! I didn't want to "break" the chrome and start the corrosion process just yet, I figured I let the curbs do that for me! lol. I've had no problems, but I've only been rolling them for a month or two. I had my wheels bored for my z-71's and all i had was a normal balancer to balance them by the centers not the lugs- and it shook a little on the highway. The guy that bored them has a lathe that was big enough to fit them- but they were not perfect. My eskies ride like a dream! And I'm ballin out of control now in the mazdalade!
