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.
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?
Actually, there was a TSB out there for the problem.The inner fender wells warp. I had both fronts replaced in 2014 and they added a stiffing brace that prevents the new ones from developing the same problem.
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?
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...
So after alot of checking and head scratching, I concluded there is no tire rub at all with my 285/40R20's. The traction control is kicking on prematurely (I can see the light flash on the dash) which makes a noise in the right front and also slows the car down a bit so it feels like a rub. I guess the Acura folks who tuned the traction control want me to slow down a bit. It only seems to trigger when there is an elevation change during the corner....
I started shopping for winter tires and would like to get something agressive looking. I may use the stock 19x8.5 rims. Any thoughts on max tire size for those rims? A taller sidewall from the 255/50R19 would be cool.
