In my case a yes it effing does.
I've had 175 60 R15 81H Dunlop Sport 300's on my car since I bought it last year.
I have had a pretty good average so far of 69mpg I've had highs of 82 and only two lows of below 60mpg. Both of those times were dues to a fuel filter replacement and a fuel temp sensor being replaced, twice (that was because I stupidly fitted the wrong one)
Whenever I've had a 62-65mpg log (5 times) it's been because of a service or my better half has been town driving, a lot.
My car went in for a checkup recently and I ended up having to change two front tyres as they were needed doing.
As time was short (I had a long journey to make the next day) I had to make a quick decision (not really much of one) as there was only one set of tyres on the shelf.
Falkens 175 60 r15 81h Ziex ZE 914s
A like for like of my Dunlops were time uncertain so I went for the only option. The Falkens.
I filled up just before I left for our 350 mile round trip. Driving my usual way should have made a return of 75mpg.
I filled up at the same garage for the same price per litre and the mpg was 67mpg. Since I have not had a long motorway trip go less than 75mpg I was a bit upset.
(Though I probably need to spend time thinking about real life instead of obsessing about my MPG.)
The car has done a typical weeks worth of driving with short hops. Baring in mind the wife hasn't touched the car this time, I would normally get 68 mpg return.
As noted in my Fuelly log.
I filled up to day. 61mpg. WTF!!!! These tyres have to go.
I have now done some research on the tyres I've just bought and they are rating E for RR resistance. My Dunlops however are C rated.
Does RR resistance make a difference?
Yes I think so.
