2010 wheel mystery???

So I am considering new wheels (and need new tires) and when I look online all sites list 17" as OEM for the 2010 Xterra SE. The issue...mine has 16". I don’t understand the discrepancy and even the guy at the tire shop was surprised to see 16s.


Does anyone else have 16" OEM?

Considering new wheels does anyone have a suggestion. The shop said with the size and the 6 lug set up there are almost no choices.

I misspoke...It is a S and not the SE hence the 16". Sorry about the confusion. There are limited choices at 16". Is there anything I need to consider moving up to 17". I have never bought new wheels before.

Am I good to do standard search on Tire Rack and just select 17"?
Will I notice a performance difference moving up to a 17"?
Do I have to consider Maine winters and wheel size?
I appreciate everyone's help and patience.

Moving to 17s will mean you need new tires as well. No performance difference with wheel sizes.
