I need 4 new tyres, looking online it seems there's f rated for fuel efficiency and then others that are c - haven't seen any better than c. Does anyone have any experience as to wether that translates to a real life gain? - eg get 1mpg or more greater with the better tyre? Given the 20 or 30 pound difference in the tyre I do wonder......

yes it does make a difference. I have C's at the moment and am enjoying my best fuel economy ever since buying the car. check my last 3 fuelups on fuelly and you'll see!

what size are you running? if its 185/55/15 check out my new Toyo CF2 proxes. I highly recommend them. It has a B grip and C fuel rating with a wear rating of 400!

that's my size.
looks like it currently has avon zv3 so I may well try the toyo ones.
thanks

you wont regret it trust me.

Yes it makes a difference, but to see it you might need A or B rated tyres. I suspect your stock tyres are already a C. Unless it's for track/ off road use I wouldn't buy anything less than a B.

be careful UFI. In EU very few tires are rated B and A for the fuel saving, the best ones i see are mainly C. The Conti Premium contacts that came with my car were E.

Continental EcoContact 5 185/55 R15 82H and Goodyear EfficientGrip 185/55 R15 82H both have a B rating.

Keep in mind it's an EU rating, we don't officially use it here . These days I only run Michelin and Conti. UFI came with ContiSportContact 2's rated 'F'. No wonder matching the official MPG is a chore (not to mention the 16" wheels made of stone). However, people who buy a Pop may get ContiEcoContact (2?) which is 'B' rated. So really, what you fit depends on what your car came with originally. 'A' tyres do exist, but they're usually not available for purchase here

I expect at least 10mpg from the Pop wheels/tyres.

You should see something close to that.

This is the full fuel consumption history for my 1.2 - you can set it to read in any units you like at the bottom of the screen.

I swapped over to pop wheels and tyres after a couple of months and the step improvement in economy is quite obvious and in the order of 10mpg.

You can also see the gradual improvement as the car runs in, and the seasonal effect of the UK climate.

I'm at 7.5 l/100 km this tank. Very happy with my new tires, with the old tires I was seeing at least 8

Here you find what the European Commission has to say about the energy labelling: http://ec.europa.eu/energy/en/topics/energy-efficient-products-and-labels/tyres

Now put the 16's back on to repeat your 'control' runs. That would separate out the breaking in factor.

I plan on doing some back to back tests of 16's vs 14's so I need a whole day for tyre swapping and test runs. Should be interesting.
