The Energy Saver A/S Selfseal is Michelin’s most fuel-efficient All-Season Passenger car tire developed for the drivers of electric, hybrid and fuel-efficient passenger cars that want to exploit their vehicle’s fuel economy without abandoning dry, wet and wintertime traction and also want the additional peace of mind their travels will not be delayed by typical tread area punctures. Designed to deliver self-sealing continuing mobility, Energy Saver A/S Selfseal tires feature a sticky, viscous coating on the inside of the tire that instantly seals nail or screw punctures up to ¼” in diameter. The Selfseal Technology is designed to permanently fill the path of the puncture when the object is removed.

Representing the forefront of Michelin’s Green X technology, Energy Saver A/S Selfseal tires can enhance vehicle operating efficiency and environmental impact by reducing fuel consumption and carbon dioxide emissions while delivering year-round traction, even in light snow.

Expanding on the technologies of the Michelin Energy Saver summer tires introduced in Europe during 2007, the Energy Saver A/S Selfseal offers exceptionally low rolling resistance at or below the levels offered by its European summer tire counterpart.

The Energy Saver A/S Selfseal features Michelin’s EnergySaver Construction combined with a unique silica-based tread rubber that helps improve engine fuel efficiency by keeping the tire cooler. This compound is molded into a symmetric design that features siped, independent tread blocks to combine predictable handling, no compromise stopping performance and all-season traction without trading fuel efficiency. Circumferential and lateral grooves direct water through the tread design to help resist hydroplaning and enhance wet traction.

Michelin Comfort Control Technology uses computer-optimized design and precision manufacturing to reduce vibrations and road noise to keep the vehicle quiet. The tire’s internal structure includes twin steel belts reinforced by spirally wrapped polyamide on top of a polyester cord casing to combine strength, efficiency and comfort.

  1. The factory installed Michelin Energy Saver A self seal tires on my 2017 Bolt EV (all electric – not the Volt gas/electric hybrid) are generally very good. They hold corners very well in wet and dry conditions, and I have worked them hard on occasion. The ride is generally smooth, though the stiff suspension on my Bolt makes it hard to tell if any of the rougher ride is due to the tires. The rubber compound could be stickier, they lose traction when accelerating from a stop on wet surfaces, and the tires spin and squeal if I accelerate a bit aggressively on dry pavement. But, the Bolt has substantial torque, so it may overpower most tires’s ability to grip solidly. After 26,000 miles on Illinois’ very bad roads, the tread looks very good, and I anticipate getting around 75,000 to 80,000 out of them based on the current level of wear. I recommend them.

  2. Sorry, runflat tires are terrible. Rough ride can be explained by short wheelbase, noise can be explained by lack of sound insulation. Overall just a small car “5”. Entertaining enough that my wife prefers over it over Jeep Cherokee Ltd.

  3. These are the stock tires that were mounted on my Chevy Bolt. The best things I can say about them is that they are quiet, smooth, and ride comfortably. All Michelin tires I have ever owned have had these qualities. It is no doubt a high quality tire. However, traction on dry or wet surfaces leaves a lot to be desired. They tend to be a bit slippery and will squeal if you punch the throttle during a low speed passing maneuver. If you are at a standstill and floor the throttle, the tires will squeal until you lift off of the “gas.” It becomes worse in rainy weather as they tend to hydroplane. Even normal left turns at 10-20 mph in dry weather have a squirrly feeling towards the end of the turn. This tire would be perfect for someone who is a “Sunday driver.” Honestly, I think GM could have selected a tire with better traction performance along with a quiet, comfortable ride. After all, many Tesla Model 3’s come standard with Michelin Pilot Sport 4s. The PS4s tire would have been perfect fit for the Bolt. In the end, I decided to go with Riken Raptor ZRs (a Michelin subsidiary). The tires handle a lot better, with a small decrease in cruising range and slightly more noise. The tradeoffs are well worth it, active safety can be a lifesaver.

  4. Had these tires on my Chevy Bolt almost two years now. These are NOT run flat tires. These are self sealing tires. Tested this out the other day. Got email indicating my right front tire was losing air quickly. Took a look, saw a nail in it. Took out the nail, was hoping the self seal worked. Once the nail was pulled out, put air in the tire and … two weeks later, the self sealing worked. Very nice. Since there is no spare tire in this car, this is a great feature. I will buy another set for sure.

  5. Running the OEM tires for the Bolt EV, they are “OK” from a performance outlook, and excellent from an efficiency outlook. Mine are at or perhaps beyond their useful life, and I just had my first road hazard problem. The drivers side front developed a leak (puncture from some kind of debris) and the object was no longer in the tire when I found the problem. The self sealing feature failed, but I think this may have been due to age (3 years old) and 55,000 miles worth of heat cycles. I used a plug kit and when I ran the rasp in and out of the hole it did pull some of the self sealing compound out of the hole… it seemed sort of dried up, not very pliable or sticky.

  6. My Bolt EV came with these tires and although they look nice on the car and are Michelin tires their performance is not well matched with the power and torque of the Bolt EV. In dry weather these tires will loose traction easily while accelerating without being in sport mode. I won’t even use sport mode as these tires cannot handle the torque of the electric motor. In wet weather they are far worse than dry almost to the point that they are unsafe. I loose traction quite often and easily while driving in the wet here as I live in the Pacific Northwest. Thankfully it does not snow or freeze here much as I don’t think these tires could handle snow well. I won’t waste these tires yet but my next set will definitely be a set of Ultra High Performance All Season tires to better handle the power and torque of the Bolt EV. I look forward to trying the Continental UHP’s or General G -Max tires next as they both have excellent ratings and can probably better handle the 200hp of the Bolt EV. I did not buy the Bolt EV because of the power but it is so much fun to drive I look forward to seeing how it will really drive with a better performing tire. Sorry Michelin but this tire would be better for a Honda Fit or Prius.

  7. These tires can not hold up to an EV in wet weather. They spin out continually steel wheels would work better. It is wet here 9 or 10 months of the year these tires only lasted 27,000 miles
