It seems the defacto new from the dealer tyres; continental premcontact 2 are not the best choice.

The eco contact 5 are a huge leap in the mpg category!

I need some soon enough, and having moved the wifes honda onto higher rated mpg tyres has made an instant improvement.

It went from 32mpg to 40mpg. A 20% saving on fuel!

 

Not sure what increase I could get from the citiGo, but it could be impressive.

 

Has any one tried tried the contact 5 or changed to good mpg rated tyres that can confirm any improvements?

 

"It went from 32mpg to 40mpg. A 20% saving on fuel!" - sounds highly unlikely from just a change of tyres.  Running at same pressures as previous tyres?  Over what mileages was previous and current mpg measured?

It is a big improvement in MPG. I'd expect a marginal gain, I am not a tyre expert though.

I think the overall max improvement of a "A" rated tyre over and "F" rated tyre is about 5-6% not 20% so I think tyre pressures and other enviromental conditions may have contributed

 

I have Dunlop blue response on my GLII and have gone from a "G" to a "B" rated tyre and seen marginal 2-3% improvement in economy and that is probably within the margin of error of the calculations

 

I would like to see if the improvement is maintained over time

And don't forget that the standard fit tyre from the factory will be a compromise between grip, durability, economy and cost. It is not hard to find a tyre that majors on one of those factors above all others.

 

As said above, I SERIOUSLY question a 20% difference just by changing tyres, unless you hadn't checked the tyre pressures for a year and were running virtually flat!

You're also giving up grip for the economy, not a tradeoff I myself would go for.

must admit the blue responses I have on my GLII I have noticed no loss of grip but a marginal increase in mpg (5%)  3mpg on avg 58-60mp on my 5 tank average

 

so tyres do play a part and the modern compounds do seem to have worked the miracle of better mpg, with pretty much the same tyre life and grip

I regularly check tyre pressures, and mpg tyres dont necessarily give poor grip (according to the link; better mpg for same grip)

a lot of the gain I gather is from rolling resistance not grip. eg take your foot off and you slow down more.

 

I would understand its hard to appreciate 2-5% because it could be a bunch of other factors, but 32 to 40 was instant and has remained over 40mpg for a good few thousand miles, so its hard to deny.

 

I am as mentioned comparing a tyre change on a Honda CRV, not the citigo, but I was asking if I might expect a decent change for following the "guides" given by the tyre shops, which suggest the current ones could be replaced by better ones.

If I were getting 40mpg in my Citigo...I'd be HUGELY disappointed!

sorry...having re-read your post, my comment is redundant!
