Nissan Patrol 4x4 (Africa)

Eye David, there are many factors that can influence the real diameter of the wheels.

Firstly, the sizes given are only a theoretical value, and dependent on manufacturer and model it can vary significantly.
Then there is the rim width, which effectively changes the shape of the tire. I doubt this is a major contributor assuming the tire pressure is adapted to give even wear across the tier surface, but it will make some difference.
Tire pressure and the weight resting on the wheel will play a roll, especially since what really matters is not really the diameter of the tire but the distance from the axle centreline to the road surface.
And probalby one of the most significant factors is the tire wear, since on a muddy the difference between a new tire and a worn-out one can be more than 1".

Wat is die effek van n 2857516 op n 4500 se krag en topspoed? Sal hy nogsteeds gemaklik 140kmh kan hardloop en teen opdraandes?

Ek weet van baie 4.5 patrols wat met 33 (285 75 16) rol geen probleem net die manne met die autos se dit werk nie great nie

Hi Marius,

I dont know about the 4.5 but on my 3.0D it did cost me about1.5k's /L. And it changed the gear ratio that I know have to use 1st gear. You dont pick up a drastic powerloss but there is loss.

On the plus side you lift your diff by an inch. This is huge when off roading. And with the diametre you just crawl rocks and ruts with so much ease. I see some people spend over 200k just to be able to fit 33's on there vehicles. Taking that cost into acount you should fit them, just because you can and without any mods

Baie dankie! 5

Indeed. I bought my car as an overlander and the standard setup is already hugely capable offroad and I did not want to fiddle with anything that could possibly mess with the factory settings, calcs, change the torque or increase mechanical stresses etc so plan to stick with the standard wheels and suspension for the foreseeable future. Courses for horses.

Toe my 4.5 Patrol standard was met die 2" lift kit, was die gemiddelde petrol verbruik 4.99km/l.

Nadat ek die 285/75R16 M/T bande, die voorste bumper met 'n winch en 'n roofrack opgesit het en 40 000km gery het was die gemiddelde petrol verbruik 4.88km/l.

Herrie hoe loop jou kar met daai bande? Is die motor standaard en watse spoed kan hy gemaklik hou op hoofweg?

Hy loop nog goed en soms op obstacles wat ek in 4LR in rat 2 gery het moet ek nou in rat 1 ry.

Ek ry mog steeds op die hoofpad tussen 100 en 130 soos altyd.

Dankie Herrie. Sukkel hy om so 125kmh gemaklik te hou?
