I've run both of these tires. I put Defender ltx on my Yukon XL and on my Ram 1500 and they are awesome, and arguably the best road tire you can get for light trucks. I also put a set of the LTX AT2 on Ford Super Duty 2500, those suffered faster tread wear but the truck was almost 2000 lbs heavier than my Ram. Those LTX LT2 were a beast in the snow! They were no different, nor worse driving in a foot of snow than a light rain. The only negative thing I can say about the ATX is that they were not horribly bad but definitely have a noticeable amount of road noise.

I've had both MS Defender and the AT2. The MS Defender is super smooth, quiet, great in rain, decent in light snow, but not 3PMSF rated. It even does a decent job impersonating an all terrain tire. The AT2 is really an aggressive all season tire. It does alright in snow, good in the rain, but it is not great in off road. As long as it's just dirt and gravel, it's decent. It's very quiet and a smootb, but throw some mud in there, and it reaches its limits. It has no shoulder tread or protection, and exposes the sidewall to side punctures. The AT2 doesn't have wide voids and the blocks are too close to grip in off road. The tread was only 13/32 deep new so it doesnt have deep blocks to grab terrain. It picks up rocks left and right and grows them into my fender liner. In fact, I finally bought a long, curved end pliers to pull rocks out. I also suffered lots of punctures. I've gone through 5 punctures and patched them up. I just got tired of it's weak performance and got rid of them at 50,000 miles. I went to the Cooper AT3 XLT and went 51,000 miles without one puncture. Now I have Mickey Thompson Baja Boss All Terrain, a truly ferocious all terrain and foul weather tire. The AT2 has been around for about 20 years without any changes or improvements. Michelin owns BF Goodrich and tells people to go to the BFG KO2 if they want a true all terrain tire. I know, I've contacted Micheling to inquire about a more aggressive tire and they had told me to go to BFG. Going 20 years without any improvements is disappointing. All other tire companies have gone through AT, AT2, and now into AT3. Even BFG KO3s are out. Yet Michelin has stayed stagnant and moribund. Their original AT tire looked better and more agressive than this AT2. Adding more siping into the AT2 would be the easiest improvement for added snow and wet traction. Nope. Widening the blocks or have larger voids would increase off-road grip. Nope. Michelin actually has the FORCE model, sold in Southeast Asia and making news in the road rally world, but no Force models being imported to the US. Doesn't give me much confidence that Michelin cares about making a serious all terrain tire.

Ive run both of these for years in New England from hot summers to record breaking blizzards. MS is absolutely the best tire I’ve ever used. AT is great in deep soft snow and rock climbing but not close to the MS anywhere else and not recommended for wet roads due to the large smooth tread surfaces that brake like water skis.😂 MS is unmatched in plowed/packed snow and ice, almost like a dedicated snow tire, safe and easily controlled in wet braking, as well as quiet, smooth, efficient in the summer and basically bullet proof. Cornering and steering feel are as good as you could want. With the LTX MS, my non-traction control solid axle running 235/75/15 rear wheel-drive conquered every blizzard effortlessly. Just make sure you add weight over the rear wheels.

My ZJ 4.0 1997 has the Defender LTX. Great tire.

I have the LTX MS, on my 2021 trd pro tundra. The ride is quiet and comfortable, wet conditions are handled beautifullyso far here as we approach summer rains in Florida. As for fuel economy, I avg 13.9 mpg city and 17 hwy. Afraid to see what any other tire would be if this tire is giving me these mumbers.

Better use up the tire threads fast on Michelin tires. I had Michelin all seasons premium top of the line (PREMIER Primacy MXV4) passager tires proudly made in CANADA. Haha! Great famous performance with a big famous name. It actually drives pretty good. Everything went south👎👇 In only 3 1/2 years with plenty of thread, then visual signs of dry rots with only about several hundreds of fine cracks lines on all sidewalls of all 4 tires smiling at me. After all Michelin's biggest advertising slogans is your life depends on how good is your tire. Brought it back to COSTCO with its famous posted black and white powerful warranty behind their beans counter. They blamed me for all the dry rots and all the sidewalls cracks. With a big no no instore warranty claim or adjustment. They asked me a double-edged sword question of " Do you use tire shine or not?" Guess what ? I said " YES". He replied back " You shouldn't be supposed to use any tire shine or rubber preservatives products ." They give me Michelin's own representatives toll free number to deal with me. The Michelin Co. representative tells me to go to one of their independent privately owned tire shop near me to get another evaluation. Guess what? The same tire dressing question? He ask me do I use any tire shine products again. I quickly realized it's a double-edged sword question. If you use tire dressing products, it means you are using chemicals that are a no-no for the Michelin tires. If you said you don't use tire dressing products, which means you don't take care of your tires. It ends up another no and forfeit warranty claim. Then, the Michelin tire rep gave me another tire shop located much farther away from this location for me to get another evaluation for warranty claim. I realize this is just another RUNABOUT GAME Michelin played to F#*k me up to get rid of me from warranty claim. No warranty claim on a 5 years FAMOUS Warranty. I will never look at MICHELIN tires again after this HALL OF SHAME GAME 🎮 they played on consumers like me. There big advertising slogan is just a big lie. ( Your love ones lives depends on Michelin.) Yes, an advertisement is a paid advertisement. That's all.

What about fuel economy?

Too many screeching sound effects.

Defender is the worsst tires I have ever owned. Like driving over a washboard
