Question Michelin Defender LTX 275/55R20 for Silverado 1500

So I called discount tire, told them I wanted to get a LT (light truck) tire for towing my 23 international FB to make it more safe in a sway situation. I told them I had a set of Goodyear eagles (pics attached) and was told by the salesperson I needed to get the michelin defender ltx 275/55r20 (pics attached) for my Silverado 1500.

The problem, the Michelin is not a LT tire, its a LTX, not the same thing, and I am not sure what to do.

The reason I wanted a LT tire is because the research I have done on the air forum lead me to believe that it responds better to emergency situations and potentially reduces sway. I have 3 kids and safety is of utmost importance.

my question for the forum, (and I would really appreciate it if you had experience in this specific issue of trying to get the specs I need 275/55r20) is the following.:

Do you think this tire is as good as getting an LT tire, and if you were to get an LT tire, which one is best to get for highway usage. I do not want to get an all -terrain tire. my tv is a 2016 crew cab Silverado 1500 .

recommendation from can am , ontario

I did manage to speak with a very helpful man named Joe Curry who works with Andy at Can AM. Believe it or not the recommended a slightly smaller tire for better performance.

either the
Michelin Defender 255/55r20 extra load Premier, LTX
or
Perelli Scorpion Verde 255/55r20

their reputation precedes them in terms of helpfulness and knowledge, and they were passionate about these 2 tire options. going to call and check with the dealer

What's wrong with an LTX tire?

While there is nothing "wrong" with an LTX, it is a misperception thinking it is an LT tire, it isn't. Like vehicles, it seems that they are trying to create a crossover tire for SUVs and Light Trucks.
To the OP, I too had the Goodyear Eagle LS/2 tires on my Sierra 1500 and they are junk, when considering towing.
Do the research and compare all the stats. The LTX are load range SL and rated for 2535lb each @ 44 psi. The tires I went with are Goodyear Eagle Sport, these are load range XL speed rating V and rated for 2833 at 50 psi. All of this equates to a stronger stiffer sidewall, which helps greatly with sway. I put these on and towed 9000 miles this summer, 6500 lb trailer, never had an issue or regret.
Hope this helps with your info gathering

Are you sure? I had four 20" Defenders put on my 2013 Silverado 3/4T - they are LT265/60R20/E and they are referred to (for marketing purposes) as Defender LTX tires. On your sidewall, see if the number is preceded by "LT" (like the LT265 I mentioned). If so, they are light truck designated.

Thanks Randy-- Michelin website (and other tire sites) has so many models of defenders it gets confusing. Curious where you are getting the load stats, etc. any links helpful just to make sure we are looking at it the same way. The can am guys were pretty passionate about considering a 255 which I thought was interesting. They said it handled better. Keep in mind I'm pulling less weight than you are though. Thanks

Yep looks like the LTX 275/55/20 is a passenger tire, with weight capacity of 2337 lbs at 50 lbs pressure ?

Well, many trucks come with P-rated tires - as I understand it, it's just a classification - the engineers wouldn't have them on the truck if not fit for use.

OP - what were the original tires on your truck? I'd be willing to bet they were P-rated tires as well.

For whatever it's worth - I have LT Michelins on my truck (originally Goodyear LT tires but I swapped to Michelins at 50K miles) and P-rated Michelins on my trailer.

I always thought the P and LT designation was confusing and that one tire line was P and another is LT. As I now understand it and to use Defender as an example, some sizes are P's and some at LT.

https://www.tirerack.com/tires/tires...XOWL&tab=Sizes

Looking at the size chart it appears this generally holds true, but i notice i.e a 275/60R/20 and a LT275/60R/20. While I look at your size it doesn't indicate LT so that means P

I'm going with the Defenders on my TV
http://www.tirerack.com/tires/tires....omCompare1=yes

but staying with the 15" Sendels and grab some higher load rated (E) Nokains to replace the GYM's

Hope this helps

Bob

Just bought the Michelin Defender LT (275 65R-18) tire load rated E with a maximum inflation of 80lbs for my F-150.

My question is what inflation setting (psi) are you using when not towing and when towing.

I chatted with the Michelin person on their website and they suggested 60lbs when not towing. Seems high to me but what are you using?

Thank you.

I've had LTX on several pickups and towed heavy with them. Never had an issue. This forum is the first I've read about a P rating, never "derated" anything in the past. Guess I've never been within 10% of blowing a tire but as many engine blocks as I've carried in the back I'd be shocked if I was always within limits.

Most blowouts I dealt with as a tow operator were caused by neglect and under inflation, not load.

As Bob said, these tires come in both P and LT tires. I just put P's on my truck because the ride is better and that is what GM specified for the truck. It is a 1/2 ton truck. I run LT's on the trailer. 80 psi on the trailer, 35-40 psi on the truck.

A good site for information is

https://tiresize.com/tiresizes/275-55R20.htm

Click on tire choices below and then a specs button will appear above the tire image.

You can also input and see what effects changing the size will have, generally going to a 255 (smaller width) will also change to a smaller ratio, which would equate to a slightly smaller sidewall, which would equal less play/sway. The other side to that argument, is that part of the suspension design (think comfort) is based on how much rubber there is between the rim and road to absorb impacts, so decreasing these will affect the ride comfort, whether you feel it is dependent on you (princess and the pea)

High end sports cars have extremely low profile tires, and handle like on rails, and the suspension was designed to work with it. The kid in town drops his car, puts on the low profile tires and the car handles corners better, but the kid needs back surgery in 5 years, because driving over beach sand is like a rumble strip. (Some factors exaggerated to make point)

While even the weight I carry doesn't require the load ability of the tires I chose, I will always choose more, rather than just enough. To me all choices are based on which piece of the puzzle do I want to be the weakest link, when the Sh*t hits the fan and that which keeps me the most well planted is not on the list. Therefore, I chose a stronger sidewall rather than a lower profile.

BOB - While I love and have had Nokians on most of my cars, I would be careful and extremely sure of my choice before putting them on a trailer. The all season aspect of tires is that they use a more pliable rubber compound, so that it can stay flexible in subfreezing conditions, this means super flexible in overly warm conditions. So while having to account for the decrease in using a "P" tire on a trailer you would also need to account for the all season aspect, IMHO it would have a big effect on allowing sway to develop easier. FWIW.

This is a good read, relating to P or LT

http://www.tirerack.com/tires/tirete....jsp?techid=70

And last, this is about load range or ply
