As a rule, (there are exceptions), lug nuts that have a taper hold on stud piloted wheels, and lug nuts that are flat at the point of wheel engagement hold on hub piloted wheels.

I was getting ready to ask about that. Thanks for posting the answer.

My experience says that:

1) Cars and light trucks use hub piloting to center the wheels. I know of no exceptions. (OK, I'll grant that aftermarket wheels aren't always hub piloted, but the car manufacturers ALL do hub piloting.)

2) There are enough cars and trucks using tapered lug nuts AND hub piloting that I don't think anyone can make a rule about the lugs vs wheel centering.

3) The reason cars and trucks use hub piloting is that stud piloting isn't as good - too many things to go wrong with stud piloting.

So are trailer wheels all the same type. .? If the spacing of the lugs is the same and the offset is correct? Same number of lugs. 5.5 inch 6 lugs zero offset.

Does this mean that you are against aftermarket replacement wheels that are not hub piloted?

So now I am confused. Does anyone know if the Airstream OEM wheels are lug piloted on the 1990's and up rigs that have tapered lug nuts?

If the lug holes in the wheels are tapered, that is funnel shaped, and the lug nuts are tapered to match, the wheels are lug piloted. If the lug holes are flat and the lug nuts are also flat, the wheels are most likely are center hole piloted. Some aluminum wheels have the lug holes drilled precisely, and use lug bolts which are flat against the wheel, but still the lugs center the wheels. The after market aluminum wheels on our '83 Excella have 4.25 center holes, much larger than the hub, and are centered by the lug bolts. The bolts go through the holes in the wheel. The lug bolts are tapered on the end, so that they may be used to mount the spare which is a lug piloted steel wheel.

All the trailer wheel specs I've run across have described the opening diameter as "center bore". This outfit interestingly called it "center hole" with a separate diameter for the "cap". Should be a perfect replacement for the orlginal Airstream wheels. Has anyone ever ordered anything from this supplier?

I pur. 4 15 inch aluminum wheels several years ago form this supplier. The brand was hi spec, price was best I could find. I can not find any fault with this bus. Would pur. from them again if needed any thing.

As I stated above, I know of many vehicles where the wheels are hub piloted, but have tapered lug nuts.

So, NO!!! Tapered lugs does NOTequal lug piloted.

Would you recommend that non hub piloted aftermarket wheels not be used in place of hub piloted stockers?

If you have a choice, no.

Please be aware that the needed for hub piloting is much more extreme for vehicles with passengers than with trailers and no passengers.

Also be aware that many aftermarket wheels can be fitted with hub rings that serve the purpose of hub piloting the wheel.

Yea, come to think of it the aftermarket wheels that I had put on my truck by Discount Tire have plastic hub pilot inserts.

It doesn't seem like these inserts do a lot of work other than holding the rim in place prior to tightening.
