G'day Juddy
The tyre pressures were in matt white 1" high in the centre of the wheel arch,you can use white undercoat or matt white both of these are available in spray cans,when I did mine I used a school letraset,and made stencils from a Vita-Brits packet, the front is 24 and the rear is 46,BUT don't run the tyres at 46 as it makes the vehicle very skitish,on my bar treads I run 25 Front and 26 Rear,with a light load,with my G'year Steel Treks, I run 45/46 and that seems to give a ride similar to conventional tyres, as that is what the suspension is designed for.
By the way: out here they are Mudguards not wings,birds and planes have wings
