In December 2020 Michelin announced the new Michelin e.Primacy, and now in March 2021, it is widely available for purchase in the UK market. Designed to sit alongside the hugely popular Michelin Primacy 4, the new Michelin e.Primacy has some incredible statistics both for electric vehicle (EV), and internal combustion (IC) drivers who want to save money, range, and have an interest in protecting the environment.
The new Michelin e.Primacy is the first tyre to be carbon neutral at point of purchase, and has the lowest rolling resistance in its class. It is built on the core Michelin principle that a tyre should perform all the way to 1.6mm, which avoids early changing of tyres, reducing the environmental impact and saving the customer money. Impressively, it is still capable of passing the EU wet braking test after 30,000 km, a distance at which some competitor tyres might be already past the legal tread depth limit!
New Technology and Features
The new e.Primacy includes a myriad of new technology designed to lower the rolling resistance of the tyre, without sacrificing key safety qualities such as wet grip, or subjectively qualities like passenger comfort. The tyre is fitted with lighter, slimmer belting, an energy passive compound, an energy airshield, cool running sidewalls, and a u shaped tread groove (see end of article.)
All these new technologies result in a tyre which has the lowest rolling resistance of its premium summer tyre class, which means it can deliver an extra 7% range for an EV, or for IC engines, it can save around 174 kgs of co2 over the tyres life, or 21 litres of fuel every 15,000 kms. This saving is effectively giving you a free tyre every 30,000 kms driven!
The new tyres EU tyre label result of A rolling resistance and B in wet grip mean it has a label score that less than 1% of the tyres on the market can achieve.
The Michelin e.Primacy will be initially available in 56 sizes, covering 15 to 20 inches, and is perfect for electric vehicles such as a Tesla, or regular vehicle owners who have an interest in protecting the environment.
(3) Rolling resistance tests performed on test benches by Applus Idiada, at Michelin’s request, on new tires in June 2020 and on tires milled to 2mm tread depth in August 2020, on size 205/55 R16 91V, comparing MICHEILIN e∙PRIMACY (new: 5.58 kg/t - worn: 5.13 kg/t) to MICHELIN PRIMACY 4 (new: 7.74 kg/t - worn: 6.25 kg/t); BRIDGESTONE TURANZA T005 (new: 7.17 kg/t - worn: 5.81 kg/t); CONTINENTAL ECOCONTACT 6 (new: 6.39 kg/t - worn: 5.49kg/t); CONTINENTAL PREMIUM CONTACT 6 (new: 8.93 kg/t - worn: 6.94 kg/t); DUNLOP BLURESPONSE (new: 7.97 kg/t - worn: 5.54 kg/t); GOODYEAR EFFICIENT GRIP 2 (new: 7.01 kg/t - worn: 5.38 kg/t); PIRELLI CINTURATO P7 BLUE (new: 6.96 kg/t - worn: 6.30 kg/t); PIRELLI CINTURATO P7 (new: 8.79 kg/t - worn: 6.97 kg/t). Results may vary depending on driving practices, vehicle and tire pressure.
It's interesting to see the delta between new and worn and how it varies between brands
this article corroborate on the subject even further https://tiresvote.com/artic...
I have that in my queue waiting to write up :)
Very curious how these will perform. It would be nice to have a set of road trip tires.
The will perform as Michelin always does, they will last many km / milles. As long as they are not kept on the rims too many years, the test of time is the one the rubber can't pass.
Michelin doesn't age out before other brands, it's just an issue with tyres as a whole, but I otherwise agree, the tyre will likely perform very well and have excellent wear characteristics.
Hopefully I'll get some to test soon!
Looking forward for a test with a 215/55 R16 or any comfort orientated size without the price and any predicted wear taken into account , the behaviour when worn I think would make more sense together with the normal safety checks(braking, handling, etc) . That only if it is possible for you.Many thanks.
Michelin are certainly pushing the worn tyre messaging at the moment so hopefully I'll be able to test it soon (wearing tyre properly is very difficult)
I think this would require some help from the people nearest to you whom can offer their used tires or if there are any used tyre centers to find what is needed. Milling the tyres has nothing to do with real road wear.
You can't take used tyres from any source other than a proper wear program as tyres that come off customers cars will have had a very different life.
Milling does have pretty good correlation in wet braking which is useful.
I've seen a figure of 1 euro per km per set which means if you wanted 10 sets of tyres driven for 20,000km that's 200,000 euros.
Amazing amount of euros , not sure it's worth the efort then.
Ok, milling the lot tested would be interesting, I would like to see what changes.
It is possible that for all your tests to aplly the milling to all the tires tested in order to give us a preview of what awaits us if we choose a tire or another as it gets close to the end of their life.
Milling to 4 mm and 2mm(Nokian has that marking on the tires the waterdrop in between the 5mm and 4mm and claim that the risk of aquaplaning increases after the waterdrop wears out/ so in order to be safe change them tires please) to see what happens to their performance .
Michelin isn't bullet proof. I only got 24k miles out of their mxm4 tires instead of the 40k they are rated for. Replaced them with PS A/S4 a couple days ago. So far so good, but I know it's going to cut the range a significant amount on my Tesla Model 3. Having a safe tire that is reasonably quiet and can improve efficiency would be a real option as a road trip tire for me.
Keep in mind that new tyres usually have higher rolling resistance than worn tyres so it might make the delta between the two larger than it actually is.
I think the tyre is not the issue in this case , the car is. Your car is as heavy as mine if is RWD and heavier if is AWD, plus it has more torque delivered to the wheels straight from zero rpm than my diesel Opel Vectra C 2.0 DTI . On my estate the Michelin tyres lasted 3 summer seasons at least a 8000 km each and I got them with the car already used by previous owner.
Power is fun but for the tyre means a shorter life.
High performance tires always have higher wear than non performance lines. Just get yourself something from touring or energy efficient lines if you're concerned about the wear
