Any anyone tell me much of a difference tyre choice makes to efficiency? I'm looking for new tyres for the Fabia VRS and want to maintain or even improve the efficiency if possible. Is this possible and if so what tyres should I be looking at?

efficiency of ?

fuel i assume you mean ?

Anything that increases friction between th ecar and the road will have a negativce impact on fuel efficiency.

So in theory a wider tyre with a soft grippy compound will reduce your MPG.

Whether or not it reduces it by an amount that you could actually noice I dont know. Ive not really seen much difference on previous cars Ive owned..

I changed the hard Michelin Pilot Primacys that my Fabia vRS came with, for softer Toyo Proxes T1-Rs. The Toyos are much quieter and give a better feel for the road, but they cost me up to 2 mpg more compared to the Michelins. Part of the difference is that although nominally the same size, the circumference of the Toyos is slightly less than the Michelins, even when new and correctly inflated, hence more revolutions per mile = less mpg.

In practical terms tyres are only one factor in the mpg equation; road surface, temperature, traffic, driving style etc all have an impact, so I would just go for your preferred tyres and accept the fuel consumption.

I am getting a set of T1-Rs fitted tomorrow, do you ever travel over sections of road that are concrete, if so whats the road noise like ?

I have got 32K out of the original tyres they still have some tread prob another couple of K miles, but 1 has a slow puncture :(, so decided might as well do all.

Any one any other comments about these tyres ?

they grip well, and wear is not that bad. After 9k of quick progress they still had 5mm of tread left.

Got a set coming for my Furby too. 215/40/16's.

Got a set fitted to nicci's clio last week. She had Continental premium contact before. The Toyo's I found have less road noise and are move comfy. Steering went lighter and in general the slightest change in steering and the car wants to go that way.

When AutoExpress did their 2003 Tyre-Test (I never throw car mags away) they found that the difference in rolling resistance between the best and the worst caused about a 6% increase in fuel consumption. Those that had the highest rolling resistance were those that were optimised for wet weather such as the Goodyear Ventura.
