Hey Skunk first off, why are you going smaller? I know you have 19 and 17 rims. Why aren't you using them. I think 17 is a great size allows for a wider tire cause I don't trust my 15here are some examples of the 2 sizes..... http://www.nlmotoring.com/XXR-522-Wheels-16x8-Flat-Black-p/52268082.htm
and here is a picture of the 16x7's..... http://www.nlmotoring.com/XXR-522-Wheels-16x7-Flat-Black-p/52267082.htm
if you notice the 16x8 has way more concave to the spokes than the 16x7... but im thinking its because of the offset +0 as opposed to +25.... any thoughts?
I would ask the guys on a certain other Versa forum. <--- I hope this doesn't get me hated by you guys. They have some good threads on tire builds.
