I have the EX manual version of the 2015
I am experiencing constant road noise over most surfaces which is somewhat tiresome
My previous Jazz's did not have the same high volume of road noise
The tyres fitted are Dunlop SP Sport 2030 on 185 55 R16 83 H -- are these tyres the problem ?
Would changing the tyres to say Michelin or another reduce the noise
I would appreciate any advice - Thank you

There are a couple of adverse comments about road noise with these tyres at http://www.tyrereviews.co.uk/Tyre/Dunlop/SP-Sport-2030.htm (http://www.tyrereviews.co.uk/Tyre/Dunlop/SP-Sport-2030.htm) and the EU noise rating is 70dB.
The Michelin Energy Saver tyres fitted on my new Jazz SE are rated at 68dB so very slightly quieter but I only consider the road noise to be obtrusive on concrete or very rough asphalt surfacing. I get the impression that the new Jazz doesn't have any significant improvement to the soundproofing compared to the previous model and it might be slightly worse (there's the temptation to save money by providing less insulation under the pretext of saving weight and hence improving mpg)..
-
We have the Dunlop's and I haven't noticed it being noisy but I have only been in the car around town. In fact I think the quietness and ride are one of the better things about the car.
-
I may be stating the obvious but have you checked the tyre pressures
-
Mines as quiet as a door mouse in a church on all roads, but then again it's a MK2 09 plate, just saying like. :-*
-
I have just got my ex CVT and it is has Bridgestone tyres and it is very quiet. :-))

Am I being naive here.....
Just been to check my tyres on Mk3 SE and they are Michelin Energy Saver.
That's three different brands on the same make and model.
I am impressed by the quiet ride compared to Mk2, and that was quiet and smooth too.
-
Would the make of tyre indicate where the car was made????
-
On my test drive of a Mk3 EX CVT Jazz yesterday, I did feel that it provided a quieter and smoother ride than my Mk1 SE CVT Jazz. But I didn't notice what make of tyres were on the car.
I would be interested to know whether, comparing a 15" wheel with 185/60 R15 84H tyres and a 16" wheel with 185/55 R16 83H tyres, there is any theoretical justification for claiming that one configuration is likely to provide a quieter or smoother ride than the other?

As far as I know EU models are made in Japan,Mexico for the US market.

You and I with the SE have the Michelin Energy Saver while the EX owners with their 16" wheels have the Dunlop. Perhaps the Michelin Energy Saver is not available in the 16" size.
Comments about the MK 2 Jazz indicated that the 16" wheels give a harsher ride due to the lower profile tyres (the overall diameter is the same as the 15").

Noisy and quiet was driving a Type R on a 2005 plate up and down to Burnley , Id get to the other end and fall out of the car totally wasted . That was an awesome drive quick motor but tiring to drive due to noise . :)

According to the Michelin UK Web site, the Michelin Energy Saver+ tyre is available in the 185/55 R16 83H size for the Mk3 EX Jazz, as well as in the 185/60 R15 84H size for the Mk3 S/SE Jazz.
Comments about the MK 2 Jazz indicated that the 16" wheels give a harsher ride due to the lower profile tyres (the overall diameter is the same as the 15").
Yes, I have heard before that, as a general rule, a lower profile tyre might provide a harsher ride. This might be a very daft question but, if lower profile tyres do provide a harsher ride, why are they fitted to the more expensive models in the Jazz range? Basic logic would suggest that, if you want a more comfortable ride, you have to pay for it. I don’t expect to pay more for an Mk3 EX Jazz and get a harsher ride than on an Mk3 SE Jazz.
Does anyone know whether it is technically possible to replace the 16” wheels on a Mk3 EX Jazz by 15” wheels?
-
I think the theory is that lower profile tyres are supposed to give better handling characteristics as the smaller sidewalls flex less. That would be good if you drive a racing car but for normal on the road driving I prefer the less harsh ride of a higher profile. Also there is the aesthetics - bigger wheels are seen as more up to date and trendy.

Not an easy job to put 15inch on the ex as the ex has tyre deflation warning which works on the rolling radius.
As I said before I have the ex with Bridgestone tyres and I have a lovely quiet ride.

My understanding from reading the Mk 3 handbook is that the deflation warning system works by comparing the rotational speed of the four wheels. There is also a recalibration facility to be used after changing a tyre or adjusting tyre pressures (which could change individual wheel's roation speeds relative to the average).
My interpretation is therefore that it would be possible to change between 16" and 15" wheels.
-
Am I missing something, but isn't the tyre and wheel diameter for a 16" wheel the same as a 15" wheel when you include the size of the tyre as well. Otherwise the car would be a different height off the road. In which case the rotational speeds and rolling radius would be the same.

I think this is correct
-
the sensor is fitted to the wheel and not to the tyre, so if you have a smaller radius wheel the sensor will be closer to the center of the wheel, so the speed of the sensor will be lower.

Sounds to me that I ought to test drive a Mk3 SE Jazz. My local Honda dealer has only an EX with CVT demonstrator, but they have other branches in the area that might have an SE with CVT.
I have a very functional view of cars. Top priorities for me are reliability, economy, comfort, quietness and practicality. Cosmetics and aesthetics are very much lower considerations.

Sounds like a Jazz then....

That's probably the nub of my problem! Where do I look for an alternative?
Our Mk1 Jazz has been a brilliant car for 11 years but it is now showing its age (although still going strong!). It has transported our two daughters and their belongings to and from university more times than I care to remember. I never fail to be amazed at how much it can carry. Would you believe that it has transported a floor standing, under the kitchen worktop size fridge, freezer and tumble dryer (not all at once, of course!)?
I'll probably end up buying the Mk3 Jazz. But, first, I have to get over the psychological barrier of being disappointed with certain aspects of the Mk3 compared to the Mk1.

This would be correct if you were driving without tyres! However, a 15" wheel has a higher profile tyre than a 16" wheel, so it is irrelevant whereabouts the sensor is, the wheels will rotate at exactly the same speed because the total diameter ( wheel plus tyres) is the same.

the distance that the sensor makes in one turn of the wheel+tyre is less how closer it is to the centre.
less distance at the same time=lower speed
it makes the same amount of turns, but every turn he moves makes less distance.
imagine a wheel with 1meter diameter, and put the sensor at 2cm from the center, and later put the sensor at 90cm from the center, in witch case the sensor will be faster if the wheel +tyre are rolling at the same speed in both of the cases?

Stupot is correct, the outside diameter of a 15" rim fitted with a 65 profile tyre is exactly the same as a 16" rim with a 55 profile tyre. This means revolution speed of the wheels as seen by the ABS sensor are exactly the same. The ABS sensors do not move position, they take their pulses off the bearing on the axle of the wheel.
The tyre deflation warning is pretty sensitive as I have to reset mine when I get new tyres of exactly same make and size fitted on one axle (normally front tyres as they wear our quicker), it you have 4 new tyres fitted the system will accept all wheels are now same diameter.
