Morning all...

I have a 2009 EX 1.4, which needs a new front pair of boots. I was very impressed with the Avon ZZ3s on my Saab 9-5, and wanted to put them on my Jazz, but they don't do them in Jazz sizes (185/55/16). What recommendations do you have? I prefer grip (especially wet) to mileage (I do 8,000 miles max a year, but drive rather hard), and am not adverse to changing tyre size so long as I do not compromise safety.

Thanks

I am a big fan of Michelin and they are always my first choice of tyre.

Due to a major tracking (alignment) error caused by my sliding the car into a kerb in the December snow, I had front tyres with minimal tread on the inside edge of the tyre. Shopping around, I found that I had only two choices: replace the original Dunlop tyres with exact replacements or to get some Continentals. There wasn't much difference in the price. As my rear tyres were barely legal too, I decided to replace the lot with (hopefully) harder wearing Continentals. I also got the tracking fixed at the same time (not worth it putting on new tyres if I didn't). The cost was £350 for the four tyres and £40 for the alignment.

There are almost the same size (0,2%) so I guess, yes but what will you gain?

Believe me its almost impossible to find a 185 55 16 tyre here. Only  you can find bridgestone ER370 (already stock tyres) on order and some stupid korean or chinese tyres .

But 205 50 16 is commoner, you can find them from well known brands.

believe me again but 205 50 16 is far more cheap than 185 55 16 here..

wider tyres look nicer IMO.

Finally im no expert but I think wider tyres increase high speed stability and cornering stability ..Am I right?

True (I even have 175/65/15   :-X)

Generaly I agree but I don't believe this would be the case with Jazz, at least not much. But wider tyres (and bigger alloys) will reduce jazz mpg economy.

  • My Honda: 2009 1.4 EX Manual - gone to a family member. Still look after it, and a 2014 EX driven by daughter.
I am a big fan of Michelin and they are always my first choice of tyre.

They don't do any model of tyre in the 185/55/16 size needed.

Our Jazz has Dunlop SP2030's and they seem fine.

First service almost due and at almost one year/8500 miles car is... almost perfect. Very pleased with it. However...

The WINDSCREEN WIPERS have a 'mechanical buzzing' noise within their mechanism. Was intermittent - some days there, other days not at all. Increasingly constant now and loud enough to be annoying at 'around town' speeds.

INSIDE EDGE FRONT TYRES: The inside edge/shoulder - just the first inch - of the original fit Dunlops  is wearing at about double the rate of the rest of the tread. Passenger side tyre not as bad as driver's side, but still not good. The rest of the tread and outer edges of both tyres are wearing as I'd expect - evenly and no sign of scrubbing.

Anyone with a 2009/2010 Jazz with noisy windscreen wiper mechanism? (It's not noisy blade on glass.)
Or uneven front tyre wear as described above? If so, what was the outcome under warranty?

That'll be the wheel tracking (alignment) that's out. It doesn't take much to do that: going over a proud manhole cover might do it, or taking a bad line over a speed cushion. Most tyre fitting workshops can realign the wheels for about £40-ish.

My windscreen wiper have been fine- no noise whatsoever, and I have been using that A LOT recently with the crappy weather we've been having.

As for the tyre wear- take it to your local garage that has wheel tracking (alignment) facilities as suggested by IvyTek as it sounds like your tracking is out.

Thanks for your replies. Overall, I can only describe this little car as magnificent.

Yeah, I'm aware that tracking/alignment can be knocked out of line as nowster describes. However I'm pretty certain nothing has been 'hit' hard enough to do that and I'm among the most conservative of drivers over speed bumps/cushions.

I'm also aware that, on any car, front wheel alignment can be set to enhance certain handling/cornering and steering characteristics. There have been some reports of Jazz/'Fit' (in some overseas markets) wandering at the straight-ahead requiring constant small twitching of the steering wheel to maintain the line. A slight adjustment to front wheel alignment can resolve this... at the expense of tyre wear.

It may well be that alignment has taken a 'knock' as nowster suggests in which case I'll  just have to 'wear' it. £40 to fix it is no big deal, but if the car wanders off line after that...

So I'm  wondering if others have front tyres wearing unduly on the first half to one inch on the inside edge...
