Question, are just the 17x10s concave like pictured below or are the 17x9s concave as well? I really love the look and would prefer 17x9s over the 10s. Thanks for any input.

17x10 pictured all the way around:

 

They can be, depends on the offset.

 

wrong

9 is flat faced
9.5 and above is concave

 

17x10 in +12, +25, +35 will have same concave face, 5zigen just used different thickness on where the bolts go to achieve the offset desired.

 

Agreed. I have 17x8 and 17x9s and the only difference is the thickness of the center section where they bolt to the hub. The bolt holes are actually just deeper on the 17x9s.

 

17x10 are concave faced
18x9.5 are concave faced

all others are flat (lame!) ... lol.

the 17x10 can vary in weight a lot, I had +12 up front and +25 out back and one set was 21.5 lbs the other set was 23 lbs, cant remember which actually, doh.

but thats a substantial weight gain over some offsets in 17x9 that are close to 17 lbs, I mean like whoa, it could be 6 pounds per corner wtf.

 

I weighed my 17x10 +35 in at 19 lbs.

 

that's odd

they're supposed to be 21 lbs
