Fuel Saving Tyres

lambo28

On my car, I have fuel saving tyres. I am Wondering if they actually 'fuel save'. My tyres are wearing out and needs to chang, so should i actually buy fuel saving tyres instead of normal cheap tyres. Also if they do work, how?

In theory, yes they do, but don't expect a thirsty car to sip at the fuel once you've got some. They work by using different compounds of rubber and construction of tyre, leading to lower rolling resistance, i.e., there's less friction between the tyre and road. Each manufacturer has their own methods, but it's usually a silica compound in the tyre allied to more efficient tread patterns.

In theory rolling resistance can be reduced by about 20%, and that will (very roughly) equate to a 5% fuel saving. On 12,000 miles a year, that's about £60-70 for an average car. Silica tyres are also better in very cold temperatures, offering more 'flex' than a traditional tyre.

Are they worth it? No idea. It's very much an individual choice. However, before saying you should go off and buy the cheapest tyre, just think for a second - those tiny rubber patches at the bottom of the tyre are the only thing between you and a tree, so think about best value, rather than cheapest.
