What to Know About Michelin – X LT A/S


The Michelin X LT A/S Costco club exclusive is a light truck tire with a good balance of durability, tread life, and ride comfort. It has a UTQG rating of 800 A A, assuring users of its quality traction and excellent wear.

Its speed ratings and mileage warranties are identical to those of the Defender LTX M/S. Despite their similarities in design, it is the less popular tire of the two with only 17 customer reviews on the Michelin website.

Differences Between X LT A/S and Defender LTX M/S


Let’s take a closer look at the Michelin X LT A/S vs Defender LTX M/S and see how both perform in different categories like dry, wet, and snow traction, noise level, and fuel economy.

1. Dry Traction

Michelin equipped the Defender LTX M/S with a couple of technologies for on-road performance. The Comfort Control Technology improves its grip on the dry road plus enhances its quietness and comfort as well.

It is Michelin’s replacement for the LTX M/S 2, and the brand has included improvements in its tread compound for longer tread life. Other than that, the tread pattern of the Michelin LTX M S2 vs Defender LTX M/S is the same as both have a symmetrical design.

Since the LT A/S and M S2 are alike in this area as well, the A/S could give the same level of dry road traction as the Defender. Looking at the reviews on the Michelin website, it seems like customers don’t have any issues with its grip, and it has a good overall rating.

2. Wet Traction

It is important to consider the traction level of your tires in rainy seasons for safer trips. We will see how Michelin prioritizes this category as we look at Michelin Defender LTX M/S vs X LT A/S.

The Defender LTX M/S has a good combination of sipes and grooves to perform well on wet surfaces. Its wet traction and hydroplaning resistance are highly rated on Tire Rack, proving the satisfaction of customers.

The same goes for the X LT A/S. Club-exclusive tires are often a discussion in forums, and a lot of positive feedback from this tire’s wet performance has been said. Clearly, either of these Michelin tires won’t give you problems in rain.

3. Snow Traction

Both the X LT A/S and Defender LTX M/S are claimed by Michelin to have excellent snow traction. However, that depends on the amount of snow on the road.

Normally, using any of these tires on light snow would be no problem. But when it comes to medium to heavy snow, a much deeper tread is required to provide adequate grip.

A usual choice for snow terrains is 3PMSF-marked tires. If we look at reviews for the Michelin X LT A/S vs Crossclimate 2 in snow, the latter, which has the 3PMSF mark, turns out to have better performance.

4. Noise Level

Highway light truck tires are expected to be quieter compared to off-road tires. Honestly, both the X LT A/S and Defender LTX M/S have features to them produce less noise.

The LTX has four circumferential channels and smaller voids, which aid in noise reduction. The A/S, on the other hand, has a poly cord to make rides quiet.

However, some Reddit and other retail sites report the X LT A/S to be a noisy tire. In comparison, the Defender tire has high consumer ratings for peaceful drives and comfort.

The Defender LTX M/S is declared to have Michelin’s Comfort Control Technology, which prevents the vibrations from the tires to be felt, resulting in a quiet ride. If you compare this model of the Defender vs LTX M/S 2, they are similar in this area.

5. Fuel Economy and Rolling Resistance

The Defender LTX M/S and X LT A/S are designed to have improved road contact, which evenly distributes forces onto the tire, reducing rolling resistance and improving tread life.

The Defender is equipped with Michelin’s Maxtouch Construction, which is said to save more than 200 liters of fuel in a tire’s lifetime. The A/S, meanwhile, doesn’t have this attribute.
