Tyre pressure by manual

[AMDFusion]

First of all let me introduce myself since im quite new here.

Currently i have RJ77 fully stock with 31x10.5 tyres which is my DD.

I manage to find Land Cruiser Manual in my car which has details about tyre pressure.

How accurate are the details?Should i follow the value or it is much better to stick with current value?(32 psi front,36 rear)
FYI,i rarely offroad mostly on the freeway..

I have same size rubber, a/t , the tyre place where I purchased recommended 36psi, so that's what I do for on road driving,

36 psi for both front and rear?

Hmm..i wonder why the toyota recommends different than most of our setup..

Hello,

The manual data is correct, provided you use the recommended tyres.

However, different model/type tyres require different pressures. If yours require 36 psi, then go with it.

I run mine at 35 psi (as recommended in the tyres' spec sheet,) which is different from the manual, without problem.

Hope this helps.

Whats stamped on the tyres over rides whats stamped on the vehicle.

The PSI stamped on the tires is for the max load rating capacity. In a lot of cases that will be way too high for daily driving.

For example on my BJ74 I have Trxus M/T's and they are "E" rated at 65 PSI. If I run them anywhere near that pressure it will wear down the center of the tread very quickly. After some experimenting I now run them at 32 PSI

Here is some good info including the chalk method for determining correct tire pressure:

On a paved road - If the difference between cold and hot is more 10% the tire is flexing too much from insufficient air pressure.
