After speaking to Toyo Australia they have refered to reference material from the European Tyre and Rim Technical Organisation (ETRTO) regarding the correct cold tyre inflation pressure.

They suggest that cold inflation for a 285/35/22 to be between 35 to 40psi unloaded and 42-45 if the vehicle is under load.

all 4 tyres?

(in metric system that would be 2.6-2.8 bar)

Thats a bit of a vague range isn't it??? Could they not be more specific?? I have mine at 40 all round - think i should have more at the rear??

ISTR there was a post recently about this.

I'm sure when questioned , Overfinch quoted 4psi more than the LR 20" pressures and yes , due to weight balance you will need more in the rears but the standard pressures take that into account.

Still looking for my 22's ..........

Also, are tyre pressure gauges accurate to within 2psi?
