Why don't you - just to prove you actually read it

Im thinking the pressures for my 1996 Land Cruiser on 5 year old tire have not changed

The recommended Cold Tire Inflation Pressure for the Cooper Discoverer S/T MAXX LT295/70R18 129\126Q tires on your 2013 LC200 is 35psi Front/Rear.

HTH

I'll start with 35.

And that install sheet is wrong. The correct Recommended Cold Tire INflation Pressure for LT285/70R17 tires on a LC200 is 40psi F/R.

Here is a link to the original install sheet: Original TRD 17" Install Sheet

Please note on page 5 of 12 the recommended cold tire inflation pressure is 40psi F/R.

Toyota later determined that since the TPMS sensors will not trigger a low pressure warning until the set pressure had decreased by 25%, this recommended inflation pressure could allow the tires to run at 30psi before a TPMS warning which might be interpreted as a violation of FMVSS (Federal Motor Vehicle Safety Standards) which require a minimum allowable inflation pressure of 35psi for LT-Metric tires.

To avoid potential fines and possible litigation, Toyota changed the recommended cold tire inflation pressure to 46psi. Here is a link to the revised install sheet that reflects this change on page 5 of 12: Revised TRD 17" Install Sheet

This revised pressure of 46psi results in a TPMS low warning trigger pressure of 35psi which is consistent with FMVSS minimum requirement of 35psi.

Thus, 46psi is not a "correct" pressure, it is a "CYA" pressure.

Run whatever you want. Believe whatever source you want. But 40psi is the pressure that yields the performance designed into the LC200.

G- thanks for the explanation! (Off to adjust my tires)

@gaijin any chance for a RCTIP on the Nitto Ridge Grappler 285/70/r17 116Q ?

@gaijin any chance for a RCTIP on the Nitto Ridge Grappler 285/70/r17 116Q ?

Yes, sir!

The RCTIP for the Nitto Ridge Grappler ISO-Metric (Reinforced) 285/70R17 116Q tires on your 2013 LC200 is 38psi F/R.

@gaijin thanks!

Hey @gaijin do you happen to have a pressure for a Nitto Ridge Grappler in a 285/75/18 on a 200?

 

[gaijin]

Hey @gaijin do you happen to have a pressure for a Nitto Ridge Grappler in a 285/75/18 on a 200?

No, I don't.

But I do have a pressure for the LT285/75R18E 129/126Q tires.

Since the Nitto Ridge Grapplers come in both ISO-Metric (e.g. 285/60R18) and LT-Metric (e.g. LT285/60R18) sizes, I had to go to the Nitto Tire web site (Nitto Tires) to see if a "285/75/18" Ridge Grappler even exists - it does not. So I assume you meant the LT-Metric size LT285/75R18.

The RCTIP for the LT285/75R18 Nitto Ridge Grappler tires on your LC200 is 40psi F/R.

Hmm I might want to increase my 129 duty lt275/80r18 up then. . . Been running at 37.

No, I don't.

Apologies for the lack of specificity, but you nailed it. The LT is the tire I just put on, so I appreciate the help! 40 is definitely higher than I would have run so I'm glad I checked with the guru.

You should contact the manufacturer and ask them what cold inflation pressure is required to support a load limit of 2,105 lbs.

That tire size does not appear in any of my reference materials.

Gaijin,

How about LT285/70R-17 BFG KO2 E Load Range on 17' x 8' wheels on a LC200?

Thank you very much.

Gaijin,

RCTIP for LT285/70R17 Falken Wildpeak AT3W Load Range C on 17" Rock Warrior.

TIA

Second verse, same as the first...

The RCTIP for ALL LT285/70R17 tires on a LC200 (I assume this is what you have, not an LX570) is 40psi F/R - same as in my sig.

@gaijin sorry I tried to do the calculation on my own but couldn’t get it! I have 285/65/18 k02s on a 2018

I appreciate it in advance!

Let me guess... you don't really have 285/65/18 KO2's, because they are not made in that size. I'll guess you have LT285/65R18/E 125/122R KO2's, right?

Guessing again that you have a LC200 and not an LX570, right?

If my guesses are correct (I'm feeling lucky!), the RCTIP for the LT285/65R18 KO2's on your LC200 is 42psi F/R.

Sorry for the late hijack. Looking for proper inflation pressure for a stock 2011 LC200 running LT285/65R18 Ridge Grapplers. Can’t seem to find it in the search.

I really appreciate it!!!
