Tire Pressure recommendation (3 Viewers)

[tominboise]

Well, how about Hankook Dynapro MT in 285/70R17, load range E?

 

[gaijin]

Hello! This is my first posting on a forum.......ever....anywhere! Please be gentle with me.
Second, seems to be one of the kindest, best mannered and run forums I've ever followed.
Third, I would appreciate 2 pressure recommendations for a 2016 LC:

Blizzak 265/60R18 110R

Cooper AT3 LXT LT285/70/R17 121\118S

I believe that is be properly posted.

IT is my understanding that LT (LT285/70/R17) tires of that size should be 39.3 psi regardless of load rating? Am I correct? Am I getting the gist?

Thank you in advance for all of your information and participation.

And Gaijin, thank you in advance as well.

Good first post - shows your priorities are in the right place - tires!

First, the Blizzak 265/60R18 110R tires do not have the load carrying capacity required for use on your 2016 LC200. I cannot recommend them.

The Recommended Cold Tire Inflation Pressure for the LT285/70R17 Cooper AT3 LXT tires on your 2016 LC200 is 40psi F/R.

And yes, you are indeed getting the gist. The precise Recommended Cold Tire Inflationj Pressure for ALL LT285/70R17 tires, regardless of Load Range, is 39.3psi; but as a matter of convention (whole numbers only) I round up to 40psi.

See? That didn't hurt, did it?

Well, Hankook does not make a Dynapro MT in 285/70R17. They do make an LT285/70R17 and the Recommended Cold Tire Inflation Pressure for those tires on your 2008 LC200 is 40psi F/R.

Gaijin,

Thank you for the response. As far as the Blizzaks go....I purchased them and had them mounted at my local Toyota Dealership. From what I understand the tires do not meet the minimum specifications needed for the GVW of my LC?

I do not doubt what you say. Do you think when you have a chance you could give me a few arrows for my quiver to ask my dealer why they sold and mounted a tire to my truck that doesn’t have the appropriate load rating? At this point about the best I could do would be “Gaijin told me so” and I don’t think that will cut it at the dealer.

For me this tire stuff is akin to Greek!......but I’m trying!!

If an explaination is to laborious I would understand. Either way thank you for the kindness!

Let's see how I can help you explain to the brainless idiot who sold you the wrong tires - and I usually don't get this excited, but having bought the Blizzaks at a Toyota dealership, it is really irresponsible. If you were the litigious type, I'm sure you could easily find a lawyer who would be happy to represent you in a case against that dealership for endangering you, your family and other drivers on the road.

OK, histrionics over.

First, look at the placard on the driver's door jamb that has tire info. It will look something like this:

From this placard we can determine that the stock tires for your LC200 are P285/60R18 and should be inflated to 33psi Cold.

Here is a link to some of the Tire and Rim Association (TRA) Load/Inflation tables re-published by Toyo which we will refer to often as we discuss further: Guideline for the Application of Load and Inflation Tables

From those published tables, we can see that the P285/60R18 tires @33psi have a Load Limit of between 2469 lbs @32psi and 2601 lbs @35psi. This calculates to 2513 lbs @33psi. The fitment of any tire that does not meet or exceed the Load Limit of 2513 lbs is a violation of the Federal Motor Vehicle Safety Standards (FMVSS).

As you will see if you read those published tables, there are basically 4 common tire designations which each require their own tables to determine Load Limits, and how those Load Limits may have to be adjusted. Those 4 tire designations are:

1. P-Metric (example: P285/60R18)
2. LT-Metric (example: LT285/70R17)
3. ISO-Metric (example: 265/60R18 110R)
4. Floatation (example: 35X12.50R17LT)

Our further discussion here will focus on the P-Metric and ISO-Metric tires.

Here is a link comparing the physical characteristics of the stock P285/60R18 tire and your 265/60R18 Blizzak tire: Rim and Tire Size Calculator

From that comparison, we can see that your Blizzaks are approximately 3% smaller in diameter/circumference than the stock tire. This means that your speedometer will indicate a speed 3% faster than stock and your odometer will indicate 3% more miles than actually travelled. This is bad enough, but not in and of itself a hazard.

Here's the big problem.

The Load Limit for ISO-Metric tires, like your Blizzaks, is determined by using the published Laod and Inflation Tables for ISO-Metric tires. Whether your Blizzaks are DM V1 (Blizzak DM V1 Specs) or DM V2 (Blizzak DM V2 Specs) they are a Standard Load tire with a Load Index of 110.

Using the Standard Load ISO-Metric Load and Inflation tables for a Load Index of 110, we find the Load Limit for the Blizzaks is a maximum of 2337 lbs @36psi.

The Blizzaks do not meet the minimum Load Limit of 2513 lbs - they are not strong enough for use on the LC200.

In summary:

The Blizzaks are too small in diameter thus falsely increasing speedometer reading and falsely overstating miles travelled on the odometer.

The Blizzaks do not have the physical capacity to carry the Load of the LC200 resulting in a dangerous situation which could result in unexpected catastrophic tire failure.

In my opinion, whoever sold you those tires should be fired.

The proper size Blizzak for your LC200 are either of these two:

Blizzak DM V1: 285/60R18 116R (Part Number 097385) @33psi

Blizzak DM V2: 285/60R18 116R (Part Number 016185) @33psi

Continuing to use the 265/60R18 110R Blizzaks is dangerous. Full stop.

My suggestion would be to ask the dealer to replace the tires they sold you with new ones of the proper size at no cost. What you do legally is up to you.

That should give you a few arrows in your quiver, but still feel free to tell them, "gaijin told me so!"

Hey, @Teton TP , any further comments/questions I can help you with?

Thank you very much. I am going to the dealer today to have the tires changed to Nokians of the proper size and load rating. It was a fight at first. Then I sent them an email, parroting what you said above, and included a final line stating that said letter will be used if there are any failures in the future. It took two hours for them to reply and offer a replacement.

So again, I thank you and my family thanks you.

Sometimes stories do have a good ending.....

If you’re ever in the Tetons you have a place to stay!

Good morning @gaijin -

My new to me 200 came with fairly new Big O Big Foot AT tires in size 275/65/18 116T. Appreciate the tire pressure recommendation.

PS...I would not have selected these tires for my Land Cruiser. They are loud. They can’t seem to balance them. They (Big O) are common out here in mountain west and an alternative to say a Discount Tire. Wish the PO would have gone a different route when he bought these tires.

Thanks in advance.

Excellent. Good job on your part to be concerned and to remedy the situation - very glad I could help.

If you have any questions about your new tires please don't hesitate to ask.

Wow, just reading through this - had NO idea that often a deviation from the door sticker is in order...

Gaijin, when able could you be so kind as to advise cold pressure for:

LX570, Latitude Tour HP - Size: 285/50R20 - the tire also has a "green x" logo?

• Size: 285/50R20 112V
• Eco Focus: Green X
• Serv. Desc: 112V
• UTQG: 440 A A

Many, many thanks!

Good sir, I looked through here to for defender LTX 265/65 R18 tire pressure. I am running them currently at 36psi cold. Is that too much? Also just checked the tire for load rating (conversation above got me thinking) 2601#, that's good right?

Thank you! I was pretty close with what I've been doing.
