Low rolling resistance tires 2018

I had Chinese tires on my XJ 750. That was a scary ride, especially in the wet.
One day the rear tire kicked out in the wet, under light acceleration in a straight line. I kicked the rear brake and pulled the clutch and managed to keep it upright... but had enough and had them swapped for real tires. Michelins or Bridgestones or whatever, I forgot.

"Be careful in the first 100 km, you'll have less grip than you are used to until the silicone coating has worn off" they said. Oh dear.
When I leaned into the first corner I felt how grippy these new tires were, how precisely it tracked with no sideway slip at all. So hard to not take the next corner flat out!

The tires my '85 Civic came on wore out in 50,000 km or so. My dad changed them for Vredesteins, which were just as bad and wore just as fast.
Then, when I took the car over, I got a set of Michelin Energy Savers which lasted 90.00 km at the front and 120,000 km at the rear, had much more grip than the Vredesteins and of course they were more economical too. They were more expensive, but paid that back several times over.

All the dealerships I took my cars to prefer to put crap tires on and are reluctant to put top tier on. They want to make money selling cars or repairing crash damage...

Edit: I was going to repost it over on my Nissan leaf dot Com but found the link is dead. Good thing I saved that little snipit.

From the article:
(Incase the link goes dead, this is the most important artifact)



The leaf can light up wenie economy tires no problem.

Funny thing is the Volts OEM Goodyear’s roll better than the Michelin offerings

That certainly fits with my Michelin "Green X" experience. Lost a big chunk of mileage going from the stock tires on my HCH1 to a set of those Green X tires. Terrible for eco.


Stock were Bridgestone B381s.

It looks like the Michelin Energy Saver all season is possibly the number one low rolling resistance tire.
Every little tire test I have been able find put the energy saver at the top for efficiency.

The good news is the highly popular ecopia ture isn't far off.
There is maybe a 1% difference in fuel economy between the 2. Most people can't even detect a 1% difference.

I feel obligated to point out that OEM tires - the ones that come from the factory on a new car - are specially designed to the vehicle manufacturer's specs - and usually rolling resistance is at the top of the list of importance (to the detriment of wear and traction, especially wet traction).

Also, let me point out that the article is from Dec 2009 - 9 years ago. Many of the tires on that list are no longer available - and since tires change on a regular basis (without changing the name), it is very likely these test results aren't valid today.

For example: The top of the list Michelin Energy Saver AS is no longer available in the 185/65R15 size that was the OE size for the 2009 Prius.

no mention of old school Bias Ply tires instead of Radials? when I was young I would run Bias ply, over inflated, & only went to radials as bias ply were harder to find, but if you can find, there are many advantages to using Radials. but max mileage will go to Bias ply, safety, stopping, road holding, softer ride goes to Radials. & now that it is cold, anyone that ever used them remember them having a flat spot in the cold morning just from sitting over night, & bumping as you drive until they got warm & then round.

Any radial tire will be a massive rolling resistance improvement over bias ply.
I read on a 4x4 forum years ago and found that a fee people will run bias ply for off road. Those guys were saying that they saw at least a 2 mpg difference, this was on trucks that were only getting 12 to 16 mpg.

Bias ply when hyper inflated do roll better than radials because of the very hard rubber compound but they weigh more

My 50 mile range Comutacar uses bias 125/80r13’s which I super inflated when I switch to radials I lost range even at 60psi.

I think it’s a case by case basis

Here is a screen shot of the tire rack article.

Those round black things have evolved since.
