Dumped runflats, and my mileage went up....

So I have to ask.....is there any empirical evidence that it is not just my imagination?

Got rid of my Pirelli Scorpion RFT tires after 5k miles, and went with a set of Nokian ONE tires for my GLC300. (excellent tires by the way, highly recommend them - made in Tennessee).

I am now just on my second tank of gas with the new tires, and I have picked up about 2 mpg. Not to mention the improved handling and comfort too.

Possible, or am I just in the honeymoon stage with my new purchase?

I did not notice a difference in fuel mileage.

The Nokian One's are designed with fuel efficiency in mind, and they ARE excellent tires.
We changed from the Pirelli Scorpion RFT to Nokian WRG4 All Weather tires and saw a bit of improvement in fuel mileage, and a LOT of increased grip in the wet. Also excellent in snow. And Heat.
That's "All Weather," not "All Season."

Huh. first time I have heard of this brand. I have only 1200 miles on the stock Pirelli and already wonder how bad they are.... seems like they may be.

I'd be surprised if you got over 20k out of them.

Same here. The 19" Pirelli's on my wife's GLC needed to be replaced at 20,000. Went with the Bridgestone RFT - a tremendous improvement over the Pirellis.

I cant wait to wear out these Scorpions. The are terrible. Michelin will be my choice. But to answer to the Op there is a measurement manufactures use for rolling resistance. Less rolling resistence, better mileage. Less weight, better mileage. I hope you are getting better mileage and probably are because RF tires are heavy......could be placebo effect. LOL Let us know after a couple of tanks of fuel!

I used to have the Pirelli Scorpions on my GL320. They are noisy after 10K and lasted about 20,000km when the wear were noticeable.
I changed to a cheapo brand, about 1/3 the price. They were very good for more than 50,000km and pretty quiet.

Now driving a GLC. I am tempted to change the current run-flat to non-run flat.

In Australia not the same range as USA. If you are in ‘the bush’, even less options.
Yes non run flats will be better, Michelin Latitude Sport 3 were OEM on some GLC Coupes, with a can of goo and an air compressor in the boot from Germany.
Goodyear All Season Eagle Sport run flats are a reasonable compromise in the 20” rim.

It has been sometime and I was wondering if you would mind sharing your experience with the Nokian One tires? I can't stand the oem Pirelli ones and would like to replace them.

EDIT: looks like you haven't been online since 2021
