Issues & Defects from factory

When I say Nissan, I mean globally. So you are right about the 18" and 19" having the same issue, as all factory specs will produce a smaller circumference than what is required for a 100% accurate speed reading. We will either have to calculate a larger TOTAL circumference or get the speedo adjusted.

Then again, maybe this design by Nissan and all manufactures is to make us all reduce our speed? hmm

remember with the 18" and 19" rims - they have the same overall height.

I got 19" rims and ran tyres as per Jap/US spec.

ie front 245/40/19 and rear 275/35/19 as opposed to Aussie front 225/50/18 and rear of 245/45/18.

if you do the calculations - the overall heights of the rims are negligible

my speedo is off too! Nissan will not adjust unless it is 10% out. I raised this issue on the forum this year.

So I do about 10km higher and I am fine - ie keeping up with traffic.
