2018 Mazda CX-9 Strut assembly question

Is the strut assembly for 18in tires different for a 20in tire in the 2018 Mazda CX-9? I have a grand touring that I bought used and it had aftermarket strut assemblies. I am trying to buy OEM strut assemblies.
 
I don’t believe so. If you look them up on Rock Auto for example it only specifies struts by engine size, not trim level.
