Michelin LTX A/T 2 on new Crew Cab

I just took delivery, yesterday, of a 2020 Tundra SR5 Crew Cab 4x4 with upgrade and off-road package.

Small mystery here. It came with Michelin LTX A/T2, P275/65R18s from the factory.

Now, the door sticker says 30 lbs in front and 33 lbs in back for P-rated tires. Sounds about right. The tires have a P-number. The Michelin website says the tire is for light trucks and SUV cross overs.

And the dealer handed over the truck to me with 40 lbs in each tire. I called and asked them if there was something about this tire that needed to be run a higher pressure (it's an "off-road upgrade", right?) and I didn't get a good answer, other than "a lot of people run that tire with higher pressure."

Well, all right. I know how to do the chalk test, and I will as soon as I get my hands on a big piece of chalk.

But was this just a dumb mistake on the part of the dealer, or is there something about this tire with this package that needs a higher pressure on an unloaded truck than indicated on the door sticker?

Some of you guys must have them.

 

What does the tire say on sidewall...that's really the only "override" that could be warranted...if max says 55psi, running 40psi would be where I put it

 

I run 35 lbs cold on all 4 corners. Tracks nice. Good balance of soft/firm ride. Wears even.

 

I just put those tires on my truck.

unloaded 43 front, 37 rear

towing 45 front. 50 rear

they chalk out perfect and ride well like this

 

My 2014 came with the TSS package, all cosmetic stuff.
One of the package parts was my 285/55/20 KOs.
There is a sticker over the factory door sticker than reads 49 PIS for those tires.
I keep 43 in all four tires.
EVERYTIME I've had the truck in for service, they reinflate them to 49..



I would think they should inflate them to what is on the door sticker and then you can decide whatever you are comfortable with..

 

I'll be darned.

Glad I joined this forum!

Thanks, guys.

 

Same.

 

I run the same tire with 36, best off And on road tire I've ever used, no road noise and they do better than wranglers in off road situations!

 

Good morning all, I have been running the Michelin LTX for 14 years that’s all Ive put on my truck 150K on it and I run them at 40psi and they last me almost 60K miles and yes they are quiet on the road.

 

Well, now I'm having good thoughts about my factory tires!

How are they in snow? I won't see a lot of that, but from time to time on trips I'll be running into it.

 

Double post. Sorry.

 

You need to look up the tire’s rating. A 111 will be less than a 117
Also LT tires are will be rated higher and therefore show a higher recommended pressure.
If you will never load up the truck or tow, you could squeak by with a Pxxx/xx/xx 111T and have a nice cushy ride. If you will load or tow, you need an LTPxxx/xx/xx E117T but it will have a rougher ride.

 

Ive now run LT and P rated tires on my tundra. With a 4k travel trailer there is zero difference in feel between the stock Michelins and LT bfg ko2’s

 

Me too!
I ran both on my 2007 and aside from the noise and harsher ride all the time the LT just seemed pricier for no real advantage to me and my tiny trailers!

 

To your original question, seems like the prep guys at the dealerships always over inflate tires because they don't actually have any idea what the pressure should be.

 

That’s my question as well..I really want to put ridge grapplers on but I need to wait until I can afford some 6112’s for the front. I want to get the biggest tire that will fit with the front lifted 1.9”. I really don’t want to blow up a credit card doing all of it at once. Especially if the factory tires are decent in snow.
