Tyres now have efficiency ratings ,in the real world how much difference would it make between the most efficient and road legal track day tyres which have the lowest ?
What? 
At a guess I'd say the most efficient tyres in terms of being kind to mpg (how the feck does that work anyway?) are the ones with the highest efficiency rating, however even though you'll get less mpg from the road legal track day tyres whilst driving to and from the track I'd think the single figure mpg on track and ripping the arse out of the tyres trying to go round corners as quick as the MX5's would probably pale the lower mpg on the road into insignificance.. or beyond it...
I can't really see getting better mpg out of a particular set of tyres on a TVR is something you can measure in 'real world' terms anyway, and if can then you must be driving it wrong...
Sorry I haven't answered your question Daz
Daz, one of my clients did 48,000 miles on a set of tyres on his BMW 730. Two tonnes of car, but the tyres were fuel efficient. The low friction meant he got better wear out of the tyres and better MPG too - averaging over 40 mpg from a 730 diesel.

real life experience switching from worn goodyear nct to goodyear efficient grip was approx +10% MPG with no other changes on the daily driver. Pressures the same before and after, it was noticeable.
To add, for a daily driver that's fine, grip levels are good , but for a tvr I agree, best tyre is the way forward that has good grip and aquaplane resistance.

The answer to the question.....
"How much economy improvement can I expect from fitting tyres with a better economy rating?" is simple...
FEK ALL!!!!
The answer to "What tyres are best on a TVR" is also simple..
Buy tyres that won't hydroplane in the wet, yet still give good dry grip.
To this end for all those that aren't addicted to track days I highly recommend looking at the Uniroyal Rainsport range
You're a long time dead
Oh and if you're driving one of these cars and still want a meaningful improvement in economy without losing all the thrills and character, you really only have one option.

In fact I'm on my third one and have covered 170,000 Prius powered miles in the last few years, so feel qualified to tell you...
The average true Prius fuel economy over all these miles is 43mpg, while 'Ol Gasbag' averages the petrol cost equivalent of 45mpg
Driven like a complete Ghay I have had 60mpg out of 'The Milk Float' but I've also had the petrol cost equivalent of 55mpg out of 'Ol Gasbag' driven in the same way.
But it's the average that counts and that will be strongly influenced by the type of driving you do, the Prius is definitely the cheaper car to fuel if you drive in the city, but get it out on the motorway where I spend most of my time and 'Ol Gasbag' beats 'The Milk Float' hands down.
The overall result is quite surprising, but based on true pence per mile my 19 year old 4,000cc V8 TVR is genuinely cheaper to fuel than a very high tech 2 year old 1,800cc four pot direct injection hybrid.
You weren't expecting that now were you
