I am pondering summer wheels and tires myself. Looking at a 20 X 9 wheel with a +38 offset. Offset for the OEM optional 20 inch wheel is +45. Below are the specs for the optional OEM 20 inch wheel. I am not looking to procure the OEM optional 20 inch wheel. I am looking at a KMC wheel that I really like. The KMC wheel is a +38 offset and is 20 x 9. Not sure if the ZDX could handle, fitment-wise, the 20 X 9.5 wheel. I think the 9 inch will suffice, but need to be sure it will fit first!!ALY71798 Acura ZDX Wheel Chrome #08W20SZN200Make/Model/Year:Acura ZDX 2010-2013Product Specifications:

I think up to 285/50R20's will fit. You will probably get some rubbing during sharp turns when parking. 285/60R20s on the front will hit the back part of the inner wheel well when you turn the steering wheel. I just put 285/40R20's on my ZDX and there is only about an inch to go bigger in diameter before contact. I used 10" wide wheels with an ET40 offset. The recommended offset for a 20x10 wheel is ET35 from this site - https://www.wheel-size.com/size/acura/zdx/2010/ - I would stick with the ET40 to keep the wheel in closer to steering axis so it swings less front to back when you turn the steering wheel.

I believe that inner wheel cover is to be under the painted molding pieces, It fit better and wont buckle like the picture shows...

Great Look ride.... I have a 2013 with 19,500 on it. Black on Black,,,,,

Coils Springs dot com now has all the sample to make springs, I just received my -1.5" from them, will post here once I've installed.

LOOKING GOOD !

Thanks and good catch on the wavy inner fender liner xxx_busa - I did not even notice that until you pointed it out. Both sides are wavy like that. I will get under there and remove the screws and see if I can tuck the liner behind the fender lip and lower trim. It is interesting that there are screws holding it on instead of the typical plastic push pins. I guess this is how it came from Acura - carfax was clean so I don't think it was repaired.. Anyone else care to share pics of their inner fender liner?

Additionally, the inner fender wells mount on the outside a quarter of the way up in the rear, then transition to the inside for the rest of the way around the wheel well.

Still thinking and pondering......Now looking at a set of KMC wheels: 20 X 10 with a +40 offset. Using resources to help me determine if they will fit without rubbing/obstruction. Feedback and suggestions welcome.

Hey guys, the wavy fender is correct, Acura says its caused by heat. I tried getting it covered umder warranty, since that's regular use stuff. DENIED. There is a service bulletin on it that requires some sort of stiffener and a decent amount of $. GREAT IDEA, to tuck umder the fender if that's possible. Can anyone confirm if it works, and maybe post a pic?

Thanks!

Quick update: I am getting some rubbing of the right front tire with my 285/40R20's when going around left bends on hilly roads when the right side suspension compresses. I am not sure where it is hitting yet, I am going to put some small pieces of painters tape on the fender lip and in the wheel well to see if i can locate where it contacts. I think the 285/50R20's might be a bridge too far...
