So im leaning towards 20x10.5 wheels rather than 22s due to weight issues. I already find the zdx sluggish so adding bigger rims will make it worse. What tire profile would be best with 20s? Stock is 19x50 and im afraid that running 20x35 will make it look too small. Your opnions are appreciated. Thanks

 

if you want 20x10.5 then I'd go with 295/40-20

 

I am a total tire sizing n00b, but I can tell you what I'm running on 22s: 285/35/22.

I think a 40 might be ideal, but I don't know about width. Sandro would know best. I was under the impression that 285/35/22 with my 22 x10.5 was almost as large as a ZDX can go without modification (Sandro, would you know more about this?)

Also, I responded to my previous thread about acceleration. If you're driving your car pretty aggressively, consistently, I'd probably go with the 20s. I mostly drive like a grandma accelerating, so I don't notice my 22s so much.
