Michelin Primacy 4 vs Primacy 3 After a long waited 6 years, Michelin finally launch the successor of Primacy 3 in 2017. Based on the press test results of Primacy 4 from 2018 till 2020, it managed to bag first or 2nd place close to 40% of the time. This makes it on of the best performing touring class tireline. Let’s have a quick look on how much improvement Primacy 4 made against it predecessor. The comparison below utilizes the EU label data and also marketing data directly from Michelin. We will use a common touring tire size of 225/45 R17 as our basis. Wet Braking Michelin Primacy 4 A Michelin Primacy 3 A Primacy 4 is able to maintain is A label ranking compared to the Primacy 3. This came as no surprise as wet braking is one of the key focus of this tireline. Aquaplaning worn Michelin Primacy 4 +20% According to the marketing text, Primacy 4 is able to dissipate much more water 20% compared to primacy 3 even when the tires are worn. Rolling Resistance Michelin Primacy 4 C ,+11% Michelin Primacy 3 C The Primacy 4 was still ranked “C” in rolling resistance which is the same ranking as Primacy 3. However on the marketing disclosure, the Primacy 4 was noted to be 11% better compared to Primacy 3. Wear Michelin Primacy 4 +20% As Primacy 3 was extremely good in wear, we were thinking what will Michelin bring to the table this time around? Michelin noted that the Primacy 4 has a 20% mileage improvement compare to its predecessor which is the cherry on the cake 🙂 Performance over life time One of the major push from Michelin with its newer tireline was to show that its performance still maintains over the tire life time. This was shown via a worn tire test* indicating its superior performance over life time. * Wet braking test, between 80 and 20 kph, conducted by TÜV SÜD product service, on Michelin’s request, between June and July 2017, on dimension 205/55 R16 91V on VW Golf 7 comparing MICHELIN PRIMACY 4 versus BRIDGESTONE TURANZA T001 EVO; CONTINENTAL PREMIUM CONTACT 5;DUNLOP BLURESPONSE; GOODYEAR EFFICIENT GRIP PERFORMANCE; PIRELLI CINTURATO P7 BLUE Summary Overall, Primacy 4 is an excellent successor product which demonstrates better wet braking , rolling resistance and wear performances. It also comes with new performance over life time features to ensure your “Safety is made to last“

When it comes to ultimate road performance during those scorching summer months, Michelin has provided two standout solutions with its new update. As now we have the Michelin Pilot Sport 5 and the Michelin Primacy 4+, and both of these tires are phenomenal in their own right, but how do they stack up against each other? Well, let’s find better understand their comparative performance, we need to first examine their sizes and specs, and then take a closer look at their unique tread Pilot Sport 5Michelin Primacy 4+Sizes18 total sizes113 total sizes 16 to 20 inches rimsRim Sizes17 to 20 inches16 to 20 inchesSpeed RatingsY onlyH, V, W, and YLoad RatingsXL onlySL and XLTread Depth9/32″10/32″Weight Range17 to 34 lbs16 to 30 lbsTread Mileage Rating30k miles warrantyNo warrantyTread PatternThe Michelin Pilot Sport 5 is crafted with a distinctive asymmetric five-rib tread design. Here all its ribs are neatly arranged to create a total of four longitudinal adding to it’s overall asymmetric pattern, interestingly, three of these grooves share a consistent width, while the fourth groove is significantly narrower. See the one on the right side, after shoulders.All ribs in the middle run continuously, meaning they don’t form proper blocks, as you usually see on other instead, you just see varying slits on all of them in terms of their thickness and length.These slits/cuts have dual functionalists, they act as sipes in wet conditions, and biters in towards shoulders, these cuts become more prominent, and that goes especially for the ones on the right side of the tread in the image above, where you see a more aggressive slits are broader, which gradually narrow as they merge with the slender longitudinal groove whereas on the other side, the lateral grooves are towards the Michelin Primacy 4+, you get an symmetrical tread pattern here. Though there are similar 3 ribs in the middle, forming 4 circumferential in a similar fashion, all these ribs are continuous running as well. They may seem to form blocks, but the cuts you see aren’t full they still do act as sipes in wet conditions, and biters in dry, during braking, acceleration and is the case with the shoulder lugs, where although you see aggressive cuts, they aren’t like that all the way the tire’s tread is made out of two rubber layers of varying rigidity. And this allows for superior grip in different PerformanceWhen evaluating dry performance, two key components have to be considered grip and handling or lateral often referred to as directional grip, is primarily influenced by the central area of the tread, as that’s where the tread meets the road with greater friction as it gets the most weight concentrations.With this in mind, it’s not surprising that the Michelin Pilot Sport 5 with more closed up tread voids, and minimal tread features on all its ribs get to offer shorter braking distances, on average.Braking distance is the direct measure of directional grip, BTW.On the other hand, the Michelin Primacy 4+ struggles to establish adequate contact with the road, mainly due to it’s excessive tread features, thereby resulting in an inferior grip compared to the Pilot Sport TractionThe overall handling capability of a tire is heavily dependent on its shoulders, as with cornering, they get the most weight distributions on them, due to inertia, you can in this regard, the Michelin Pilot Sport 5 is again taking the lead with its relatively larger shoulders, providing superior lateral traction values, measured by g-forces.In contrast, the Michelin Primacy 4+ has a softer compound, with greater tread depth, causing its lugs to bend a lot more, leads to slightly delayed steering feedback, which can ultimately limit the tire’s handling PerformanceWet traction comprises two vital aspects wet grip and hydroplaning ResistanceIn essence, hydroplaning is a condition, where a tire loses grip and glides or floats on a watery surface, with the thin layer of water formation between the road and the scenario occurs when the tire’s grooves can’t effectively displace water, hindering direct contact of the rubber, which mostly occurs on higher speeds. That’s why it gets measured with, what they call “float speeds”, which represent the maximum speed a tire can attain over standing water, before it begins to said that, on both curved and straight aqua tests, the Michelin Pilot Sport 5 demonstrates superior float speeds. Despite having a tread depth of 1/32″ shorter than the Primacy 4+, it still offers better water evacuation capabilities, thanks to its wider longitudinal GripWhile most water is expelled from the tire through its grooves, contributing to hydroplaning resistance, the left-over water particles are managed by the tire’s sipes, offer slits in the tread, which temporarily hold water particles in, allowing the rubber to effectively meet up with the road. As water is not compressible, that’s the only way, a tire can grip.And in this regard, the Michelin Primacy 4+ only does it feature a greater number of sipes and biting edges across the tread, but its relatively softer tread compound also contributes to its superior performance as softer compound allows for increased flexibility of the sipes, allowing them to contract and expand more effectively, so that they can disperse residual water UsageThe Michelin Primacy 4+ is one of the most lacking tire in its category, when it comes to fuel this is because its lugs are more susceptible to bending, as the tire turns or brakes for tire’s softer tread compound and relatively greater tread depth both contribute to this excessive lug a result, more energy is expended in reshaping the lugs than in the actual rolling of the tire, leading to higher fuel the other hand, the Pilot Sport 5, with its stiffer compound and fewer biting edges, does the opposite, providing you with relatively superior fuel LifeThe Michelin Primacy 4+ although features a larger rolling resistance values, it’s overall treadwear is still saved due to its slightly larger tread though there’s only a difference of 1/32″, its still enough to allow this tire to have just as good of a tread life, as the Pilot Sport the tire’s somewhat lighter weight is also helping it NoiseNoise is simply put, due to flow of air across the tread. The air particles basically hit around on the walls, and the impact is what causes the noise although here, the Michelin Pilot Sport 5 isn’t a great tire, compared to other options out there, it still does better, when you consider the performance on Primacy 4+.But why is that?Well, mostly because of in-groove resonance, which is actually the echoing of the sound-waves inside the softer tread compound, the Primacy 4+ simply produces more of that, rendering it one of the loudest tires out there in its category.To Sum UpIn order to evaluate the performance of these tires, we tested them out for several key factors including grip, handling, wet and dry traction, fuel efficiency, tread life, and noise dry roads, the Pilot Sport 5 took the lead in both directional and lateral traction, while Primacy 4+ feel short in establishing sufficient road contact due to its excessive tread features, so it came out with longer braking distances and handling the opposite happened on wet roads, where you see superior griping and handling on Michelin in terms of hydroplaning resistance, which is also a crucial element of overall wet traction, the Pilot Sport 5 remained for fuel usage, the Pilot Sport 5 is a better pick, with its lower number of biting edges. Whereas the Primacy delivers superior tread life.
