I'm almost postive its gonna be 5x120... but does anyone know what the width and offset of the wheels are?

 

What are the specs of the OEM ZDX wheel?

The only published info I can find is:
Wheels 19x8.5-inch cast-aluminum wheels
Tires Michelin Latitude P255/50R19 103H M+S all-season

So other items would be nice to know are:

Offset: (MDX is 45, but the standard wheels are also narrower at 8.0" wide. You wonder if Honda really going to lower offsets like 38mm for the 8.5" and 30mm for 9.0" wide wheels ?
PCD: (I cannot see them being less than 5x120 given all the recent vehicles have been.)
Lug bolts: (Probably still 14x1.5?)
Lug Seat: (I am guessing it is the Honda spherical seat that seems to be common now, in favor of the flat seat with washer)

 

cool... still great info to know... but was looking for the 20" specs.

 

Acura says the 20" AHX-S6 ALLOY WHEELS use 275/40ZR20 tires which Tire Rack says are Michelin Latitude Tour HP's, W (that's optimistic) rated tires

Still got nothing on the offset, PCD, lug seat, and weight


Acura further says the wheels are:

One-piece cast wheel with a “Rim-Rolled” foraging technology to improve the wheel strength and reduce weight

which tells us that the wheels are made by Enkei (not a surprise as they are the manufacturer of many Honda and Acura wheels) using their proprietary MAT process described below:

RIM-ROLLED FORGED TECHNOLOGY
Enkei developed a new manufacturing process to produce the next aluminum wheel generation. The Most Advanced Technology (M.A.T) combines one-piece cast wheel technology with a rim forming technology called spinning process. Using this new technology of casting and rim forming by M.A.T process, is critical to improve drastically the material property and strength of the wheels. Rim-Rolled technology shapes the rim to improve material elongation withoutsacrificing the wheels hardness.

 

sounds good!

 

OEM wheel I'm not sure on, but the Factory 19" accessory wheel is listed as 19"x8.5" with a +45 offset recommended tire is Mich Latitude Tour HP 255/50R 19 103H. The 20" accessory wheel is a 20"x9" with +45 offset reccomended tire is same tire but in 275/45R 20 108V.

I would assume that the 19" accessory wheel is the same spec as the OEM but with a different appearance.

 

Great info! That is what the OP was looking for.

Do you know if the PCD is 5x120, and if the lugs 14x1.5 with a ball (spherical) seat?

Thanks

 

I've got nuthin' on the bolt pattern or lug seating.

 

20x9 + 45 THATS IT! thanks guys!

 

Now, gotta find a 5x114.3 to 5x120 adapter...

they exist the other way around very easily for the BMW guys.
