What's the significance of the random number in small type?

its the date backwards

 

[bgunn]

Right... :nutter:

(that's not aimed at you, dave)

Where does the idea that the EU tyre label system is a non-standardised test come from?

the eu own website

already posted above, post 101

Dave - are you saying the information on the EU Label in relation to Noise, Web Braking and Fuel Efficiency can not be trusted and that there's no standard procedure in place to ensure consistency in the way that it is measured ?

… & the supporting evidence? No doubt you’ll want to cite a reference (?)

Here’s one I prepared earlier …

Note words like `standards’ `mandatory’ `must be’ `binding’

That's a meaningful reference document.
On a side note when I was looking for contributions on a thread where I had different speed ratings on a car that I had just bought - I appreciated your inputs.

He feels the need to date stamp each of his posts for no reason at all.....

It seems like a good idea to me.

I agree.

Friday, 26 April, 2013, at about 10.21am. Drinking tea whilst browsing the FIAT forum at work. Not drizzling outside.

It's getting like Facebook on here ; )

I also agree Friday, 26 April, 2013, at about 10.40am. Having a **** in a portaloo at work as the toilets are being refurbed. Sunny.

Back to topic, has anyone got anything to say about these tyres as I'll be needing a new set for the Panda this summer & they're the best tyre I can find for fuel economy & road noise. Bear in mind that they'll never be asked to do more than about 55mph.

The temptation to try them out on the 500 will be very great indeed.

Update: The plot thickens - there's no reference to this size being available on the Yokohama website . What's occurring here??

Update 2: They are seemingly also available for the 500.

 

[306maxi]

Being Yoko's they will be decent enough.

11:33am, walking down llandudno high street, a chill in the air but gorgeously sunny.

What mileage has the Panda done? I'm a little surprised it already needs tyres

Me too, but FIAT aligned the chassis with a rubber setsquare .

It's around 32000 miles just now; I'd say they've only got about 5-10k left .

Acceptable on the front, but p**s-poor for the rears on a lightweight FWD car.

 

[306maxi]

I'm just about to pass 50k in my 500 and it's still got 2 original tyres on the rear, the fronts would still be on if not for the garage giving me shedloads of toe out. The part works i got to replace were about the same in terms of wear, I've got another 10-15k in them i would say. The winters have done about 15k of that mileage I'd guess.

They didn't do too well in the 14 inch test with ADAC getting the middle of the pack.
Did notice on the mytyres selection that in 13 inch it has the highest fuel efficiency rating (only one getting a C rating) - so if that's what you're striving for I would be inclined to agree with Maxi that they will be fine.

Bridgestone were the same with the RE040s for the F500 15 so I wouldn't mind that.

That's where I started out from. Rolling resistance makes a bigger difference to economy the slower you drive.

Thing is, can you trust the labelling, or is it more smoke & mirrors .

 

[bgunn]

Inflate your tyres to 4bar and you'll have much lower rolling resistance. Tyre might go bang if you hit a pothole, but you'll save lots of fuel!

Friday 26 April, 2013. Closed a few calls at work, currently sipping a cup of tea and catching up on new posts on the FIAT forum.

If I had to pick one (without going into it too much) I would pick the Michelins Energys. The Conti Eco has been criticised for not handling well despite getting the no. 1 spot. The Michelins have had a excellent track history. Plus they appear to be marginally better in wet braking given that it's an Eco tyre. The difference between a C & E may be very little since there's no D.

I don't think you'd joined the forum when I was musing on the idea of fitting 4 space saver wheels & 135 ecotyres .

Driven sensibly, it'd be fine - but I'm not sure how I'd explain it to the insurance company.
