You can search "Tire Pressure" for posts by me in this forum for all I've posted on the subject, but here is one of my posts that pretty much sums up the rationale for recommending 40psi F/R for LT285/70-17 tires on aa LC200:I was actually pleasantly surprised with the soft ride at 55 PSI compared to the Coopers that were on it. I appreciate the info, but what about the recall that Toyota did for the Tundras that resulted in them recommending 46 PSI for these tires? The 200 is at least as heavy as a Tundra 4x4 CC, isn't it?
I'm well aware of that tire pressure recommendation and those stickers which show 46psi (I have one, but there is no sticker available for the Land Cruiser which shows the correct spare tire size). That doesn't change the fact that 46psi is an incorrect recommendation.Here's a picture of the label that they put on Sequoias and Tundras fitted with RWs and LT285/70/17s as a result of the recall....The sticker for the LC is a different part number because the spare tire size is different, but the Toyota PSI recommendation for the LT285/70/17 tire on a LC200 is the same, 46 PSI all around, confirmed by another Mud member with the sticker.
There is, in fact, a unique sticker for the LC200, stating the spare tire size as P285/60/18. This was confirmed to me by a member on this board that ordered the sticker and put it on his LC. The part number for that sticker is in the picture above. So you are saying Toyotas engineers did the math wrong?I'm well aware of that tire pressure recommendation and those stickers which show 46psi (I have one, but there is no sticker available for the Land Cruiser which shows the correct spare tire size). That doesn't change the fact that 46psi is an incorrect recommendation.
It was actually a "voluntary non-compliance campaign". The TPMS in the vehicle was set for the P rated tires at the factory, but the RWs and LT tires were added at the port or the dealer, and when that was done the TPMS wasnt recalibrated for the added pressure.I have couple questions:
What kind of accident happened with tundra to promt a recall and was a specific psi involved?
If we take tundra gwr into account with recomended psi should it be 46 or 40 for lc?
