My big bitch is the speedo. It's about 8 - 10 % to fast - according to a GPS. I mentioned it to Nissan at the 1000K inspection. They said they drove a Commodore behind it at 70 Kph and it was the same. All that proves is they are both wrong. Does anyone else have problems with the speedo calibration.

When I'm at 109kmph, I'm actually doing 100kmph.

I'm starting to think Nissan got the tyre specs wrong and the overall rolling diameter is whats causing the innacuracy.

The thing is, if the indicated speed is higher than the actual speed, then the rolling diameter (circumference) is slightly too small (and not rolling the car the distance the speedo thinks it's going).

To fix this we can either get taller side % profiles, but I'm not exactly going to do this as the side wall profile already looks too fat for an 18" rim compared to other cars.

Hopefully Nissan can adjust the speedo calibration at a service? I'll look into this when I get 19" and new tyres in the profile I want.

Just my 2c worth of daily rambling

nope that doesnt fix it.

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.

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

That makes the most sense. I guess they figure that with a car that just wants to go faster and faster, we aren't going to get a ticket as easy.

My speedo is also close to 10% over actual speed, this really annoys me. Having to calculate your actual speed if you are coming up to a speed camera is ridiculous. I don't think it unreasonable to expect my speedo to tell me my correct speed. Apparently in Australia speedos are allowed to read up to 10% high, but they must not read lower than actual speed.
Why they can't get it closer than 10% I don't understand. It is to improve the 0-100 times (actually 0-91) ? Does anyone know how it would be adjusted in Nissan did it ? Is it an electronic adjustment ? Can the Dealer Service do it ?
I am hoping that a new set of 19" rims with different profile tyres will make the speedo read a bit closer to what it should be anyway.

My biggest issue with reading over the actual speed is that it encourages speeding. We all know that 100 is not 100 so we get used to doing more. It's hard to do 108, so we settle for 110, which is actually a couple of Ks over - assuming 8%. Then you start getting complacent about exceeding the speed limit and the limits don't mean much any more. It's OK to do 70 in a 60 zone but that's even more over the limit.
If the speedo read what I was actually doing, I'd have a hard limit - the speed limit. At the moment, I just don't care that I'm going to fast because the speedo always reads way to high.

My 0.018USD worth.

I found that all the cars i've driven basically over estimate the speed, probably a safety thing...

Wheels magazine also show actual vs shown speed in some of their reviews. at 100kph most cars are doing 92-97kph from my observations. The problem is when you factor this in to your driving =)

another vote regarding crap nissan paint quality

the front bumper has a yellow tinge to it, the rear and sideskirts too but less noticable.

I've been bugging nissan over the last month but they're saying "its normal" - a bit annoying since ive seen nissan micra's with better paint matching.

kdo2milger · 12-22-2009, 11:30 AM

thats due to the parts you described being plastic...

painted plastic verses metals with the same paint code will undoubtedly have some slight tonal variations to them...less noticable in darker colors and more noticable in lighter colors...

nissan isnt the only auto maker with this unfortunate side effect, many auto manufacturers experience this same issue...

ex: my 04 ford is oxford white and it has the same yellowing issue on the front/rear bumper as well as the side moldings...

Nissan won't do bannanas as I've already tried. They say they'll only correct if more than 10% difference.
