I've just noticed that my tyres have the markings "Treadwear 240 Temperature A Traction A". What is the significance (if any) of these markings?

The treadwear figure is used in the US and gives an idea of the hardness of a tyre and potential longevity. Based on 100 as a base figure, a 240 tyre is 2.4 times harder than a 100 tyre - so should last 2.4 times as long. IIRC it's not a recognised system in the UK/EU as the hardness of the base level is not agreed amongst manufacturers.

Thanks daveyjp. Just about everything you might ever want to know about the technical aspects of tyres.

>>I've just noticed that my tyres...
"noticed" ? What, as in, "as I crawled past my car on my hands and knees staring at the tyres instead of looking where I was going, I happened to notice that....."
Questions need to be asked, I think.

And an answer you shall get!
I was doing my weekly check of the tyre pressures and as I waited the second or so necessary for the gauge to reach a stable reading I glanced at the sidewall of the tyre (to check for visible damage, as is my wont) and noted the markings. After increasing the pressure to the recommended level I then slithered round the car and did the same to the other three tyres. Us gasteropoda slither, not crawl!

You may find this link of interest. It is a American site, but a lot of the information is valid for us in the UK.
