Michelin LTX M/S versus Michelin LTX M/S 2 - Which Would You Choose?
Suppose you had to choose between Michelin LTX M/S or Michelin LTX M/S 2 tires? Which would you choose?

Here are the links to Michelin's website for both:

LTX M/S | Michelin Tires

LTX M/S2 | Michelin Tires

Assume whatever AS you like and assume the price is the same for each.

Which would you choose and WHY?

Price being equal, I'd go with the LTX M/S2. They can carry more weight than the original LTX M/S. To top it all off they are cheaper than the LTX M/S on Tire Rack. Both have an A for Temp. That is a great thing in Texas.

I had this same question and emailed Michelin in South Carolina for an answer. The popular 225/75/16 is not being released in the M/S 2 version until the 4th quarter of 2012. Only the M/S 1 is available now in that size.

Given that my Marathons likely won't last that long :angry: I'll be going with the M/S version 1.

Silver' may have answered the question—if M/S 2 isn't available, no choice.

But, if it is available, I'd look at the predicted miles for each—they may tell you estimated miles, or warrant them for different miles. This may be a function of tread depth or different rubber. It relates to cost, which although the OP doesn't want us to consider it, I always do.

Using 5 years as the upper limit to use the tires (people disagree on that too and I think Michelin says you can go longer), how many miles will you travel after you buy tires? If the answer is 25,000 (probably more than most people travel), buy the M/S version that lasts the shortest time assuming it is cheaper. If it is 50,000 miles (more like us), buy a longer lasting version. If I recall correctly, the LTX M/S is supposed to last 50 or 60,000 miles. It's on their website.

What are the other characteristics of the tire—tread design, how quickly it stops, performance on wet and snow surfaces. This can matter depending where you live and where you go. Smoothness of ride is not too important I think, because Michelin engineers tires for a smooth ride.

We did not have to decide. Only the M/S version was available when we switched. M/S 2 was available when we got tires for the 4Runner and the price difference was inconsequential or only the M/S2 was available in that size (memory lapse). We got M/S A/T2 load range E for the Tundra because they would last a very long time and we put them on as the crummy OEM Goodrich tires were wearing fast at 18,000 miles. Even though they are nominally all terrain, the A/T 2's ride more smoothly than the P load range C rated OEM tires.

I believe the M/S load range E version will support the weight of any Airstream trailer. Weight is directly related to air pressure. You will be running the tires at less than the maximum pressure and that can equalize any weight differences between tires.

So, choice is dependent on factors different for each application, but I hope my thought process offers some help.

Great responses! I appreciate the advice. As it turns out, I'm upgrading 14" to 15" on my 17' Sport....and as it turns out the MS and MS2 are both available in 15". My dealer is telling me that the MS is better than the MS2 in terms of puncture resistance as it has more belts than the MS2. I can't find anything to support that statement. I'm interested in tread wear and such just like the next guy, but in the big scheme of things if I could have one feature in a tire it would be that it wouldn't go flat due to puncture.

Does anyone have any info that compares the puncture resistance of each of these two tires?

We recently saw a brand new Eddie Bauer 25ft front bedroom trailer on display at Windish RV in Lakewood Co, and saw that Airstream has placed Michelin LTX M/S 225X75X16 tires on it. I immediately called Airstream Inc and Randy in Customer Service said the folks who spec'd the trailer from Eddie Bauier requested the Michelins in the build.

Wayne&Sam 05-16-2011 08:28 AM

The MS2 looks like an improvement in all aspects rated on their web site. I like the look of the tread better too. But I already have brand new MS1s so by the time I need replacements I will probably be looking at MS3 or 4!

RossFam05BH 05-16-2011 09:08 AM

I just picked up six MS/2s p235/75/15 for a 34' Excella I need to pick up in CA. The load carrying capacity is different for the tires I purchased and those described on the Michelin website: 2183 lbs.@50 psi for the 6 I purchased and 1985 lbs.@50 psi for the tires specd. on the website. My tires also have added text on the sidewall stating "extra load carry capacity", or something like that. Same item# 36210 as the website MS/2s. I bought the 6 tires at Sam's club in Winston-Salem, NC on April 30 with a $70 discount on 4. Maybe our Sam's Club made some sort of a special purchase? I will post more info. on the road and in 3 weeks when I get back to NC on how they run on the 34' if there is interest. I've got to get on the road now; 2800 miles hopefully by next Thursday.

That's the tire being recommended by our local dealer and saves having to change the rims. My concern was the Load Range C of those rather than D of the Marathons currently on the trailer.

I've bought the 16" Sendel T03 rims and am waiting for the 225/75/16 which are Load Range E due to my concern about the Load Range on the 235's.

Gene 05-16-2011 11:32 AM


Are these P(assenger) tires rather than LT tires? I think you'd better look further into this because passenger tires may not be appropriate for a trailer. They appear to be Load Range C rather than the recommended D or E. I know the weights on the tables seem to make sense for some P tires, but I think they are engineered differently and are for cars and some light pickups.

Our '07 Tundra came with P tires, Load Range C. That seemed strange. They were low quality Goodrich tires and were wearing quickly so we got rid of them and put Michelin LT Load Range E tires on.

i used P tires on a car trailer for 1 trip for 150 miles. the handling was terrible compared to the prior belted trailer tires. i'd return those tires.

Have you considered XPS Rib?

To my knowledge, they are the only tire that Michelin advocates for RV use.

Heavy and expensive, but all steel construction for peace of mind...

That's gotta' make for a really rough ride :lol:

I did look at the XPS Rib but since JC is selling the LTX 225/75/16 as an upgrade I figure it would be fine.

It's only rough if you air it up too much. I found as long as you match your weight to the pressure table, it's just fine.

Gene 05-16-2011 01:42 PM

Some people get the Rib and are happy with them. They have a sturdier sidewall than the LTX and that may help with lateral pressure on the trailer—primarily while backing or if the trailer is susceptible to sway. The idea of ST tires was a stronger sidewall reduced sway.

But, we have no sway issues with the LTX. The Rib is made for commercial trucks and to be used for many, many miles because they are designed to be recapped one or more times. Basically for local travel, but a lot of it. I don't think this compares to trailer use.

We are now at 21,000+ miles with the Michelins on the trailer—my wife just updated me on the miles. After wintering (6 months) the Michelins had lost no air; all were the same pressure. The Marathons always lost air over time, especially if traveling.

I have been using the XPS LRE 16 Rib on my Sprinter service van for 3 years and 78,000 miles. The van weight around 8000 lbs. and they have given me great service at 80PSI rear and 790PSI front. They are just now beginning to show significant wear on the shoulders. The ride would be graded 'satisfactory' and not harsh in any way. I will definitely put them on the new '11 Sprinter when the OEM Contis (garbage ride) wear a little more.

Lew, with 790 PSI in a tire I sure would expect wear in the center instead of the shoulders. I'm surprised the tire could hold air at those pressures.

I could not resist.

But more seriously, isn't the Rib designed more for a use like a service van than for a trailer? And any Michelin, Rib or LTX has got to better than the "garbage" OEM tires.


lewster 05-16-2011 05:25 PM

Ahhhhh, isn't a slip of the keyboard wonderful! That was 70 PSI:blink:

I think HowieE uses ribs on his trailer. I had Goodrich Commercial T/A 16" LRE on the 19CCD and they were great. Had them on the Sprinter also, but preferred the ride and handling of the Ribs on the van over the T/As.

RossFam05BH 06-07-2011 10:16 AM

Hey All,

See previous post earlier in tread from Rossfam05BH for context.

Just returned from my trip across country to pick up a 1989 34' Excella. I installed 6 p235/75/15 Michelin LTX M/S 2 tires before leaving California for my trip back to North Carolina. Tire pressure was set at 50 psi, which is the max listed on the side-wall for these "extra-load" tires. I also installed a new Propride Hitch for the trip. Towed at 65 mph all of the way, except of course in CA where the speed is restricted to 55 mph for trucks towing trailers. Towed perfectly. Tires ran cool, never rising more than 20 degrees above ambient air temperature. The true test for the setup happened in Nebraska on I-80 when 25 mph crosswinds from the south were encountered. I had no problem controlling the rig and staying in my chosen lane of traffic. After 2900 miles, I feel the Michelin tires were an appropriate choice for our "new" three axle trailer. I don't think these tires would function as well on a two axle rig, such as our 30' Bunkhouse where I have installed Michelin 16" XPS Ribs.

BTW, I need to thank Sean Woodruff at Propride for running his business in such a profession manner. I had the new Propride hitch sent to CA, and the truck end of the adjustable stinger did not make it to CA from MI. I called Sean, and without hesitation he offered to ship a replacement part overnight, which I am sure cut into his profit margin. I received the part the next day and I then left for NC. Sean now has my business for life, and I will be replacing our Hensley on our 30' Bunkhouse. Anybody need a Hensley?

Glad you are happy with your tires and you may be the only person to observe the trailer speed limit in California.
