Tyre labels will, sadly, say nothing about burnoutability
The way we buy tyres is about to change. Eco-rules from Europe mean tyres are gaining labels just like the ones on washing machines and fridges. Anyone selling new tyres will have to show customers the label for the tyre they're about to buy.
However, when most of us buy tyres it's all about the grip, so that you can stop, go and turn (often quickly), rather than causing as little damage as possible to the environment. So, the EU powers-that-be have also put some grip information on the new labels. How nice of them.
So the new labels, which will start appearing in June this year and will become mandatory from November, will carry information about three things: rolling efficiency, noise and wet braking.
The ethos behind the labels is all very worthy, but, as we all know, PHers are a little more concerned about the rubber on their metal than the average A-to-B driver.
What it all means
The 'best' performing tyres in the three tests will score two 'A' ratings plus a single black mark and a low number for noise.
Many eco-cars, such as the VW Bluemotions and Skoda Greenlines, have deliberately low rolling resistance tyres fitted so that tyres take less energy to propel them on the road.
The grades run from A to G, with D not being used to accentuate the difference between good and bad tyres.
If you want to get technical, the difference between each grade means a reduction or increase in fuel consumption of between 2.5 per cent and 4.5 per cent. That's a difference of about half an mpg for a 36mpg car per grade.
Wet grip, as you could guess, relates to the tyre's ability to stop a vehicle on wet roads and can be expressed in terms of distance. The grades used for this test are A to G, again with D not being used in order to show greater differences*.
The difference between each grade means an increase or decrease in stopping distance of between one and two car lengths (between three and six metres) when using maximum braking from 50mph.
* Actually G isn't used either, because that would be below the minimum legal standards for a new tyre.
This is the external noise made by the tyre and is measured in decibels. The more black bars shown on the label, the louder the tyre.
Sounds simple enough, doesn't it? The label will tell you some limited, but useful, information about your next set of tyres. Although you'll probably get more detailed performance information about things like dry braking, cornering grip, cold weather traction and so on, by reading a tyre test.
Normally when you buy a new car you have no choice and little idea what brand of rubber will arrive. This is despite the fact that, when you order a new car, even without changing wheel size, it could arrive on one of four or five tyre brands due to the way car makers work supply agreements with tyre manufacturers.
So what'll happen?
By November 2012 one of two things will therefore happen with new car sales and tyre choice.
The first is that buyers will be able to select which type of tyre they want on their new car and be shown a choice of labels. The second option is that car manufacturers will insist all tyres for a particular model of car have the exact same scores on the eco-label.
With the implementation of the new rules not due for several months, experts say this last point could go either way. However, the labelling should at least give a level playing field and a start-point for tyre choice, much in the same way that 0-60mph figures don't tell the whole story about a car's performance, but do give a useful indication.
