Which tire pressure on road?

[[DO]Ron]

So, what tire pressure do you run on the road / tarmac / asphalt?

As you might know I got my 120 about a month ago and with a 2 week holiday coming up with quite a few trips to be done I want to check my tire pressure to be sure I’m good to go.

But what should it be? The manual says 2.0 bar (or about 29 PSI). But that seems a bit low to me? Stock tire size is 265/65 but I’m running BFG KO A/T in 265/70 no idea if that changes things?
I’m thinking at least 2.2 bar (32 PSI) sounds a bit better..

Any way, no idea what tire pressure they are on now, but I just want to know what to aim for :).

This is the method I use: https://www.tundras.com/threads/tire-pressure-chalk-test-how-to-guide.2114/

There are many guides on the web for this and all are basically the same.

As most of us change tire sizes, load ratings, amount of weight we have strapped to our chosen vehicle etc. you should go through a process like this to establish a baseline.

I tend to do this when I change tire brands/models or do a major weight change on the truck. I do once cold, then after a good drive try to find a spot to do it again to verify the amount of pressure gain from heat and make sure its not too far off ideal, and adjust if needed.

Hope that helps!

More than you ever wanted to know about tire pressure given the vehicle size, weight, tire size, and tire type.

Indeed.. more then one understands as well lol. I will drop by the garage and talk it over. But I think 32 psi / 2.2 bar will be what I will use.. rig is never really loaded that much and no huge roof racks or anything yet so should be ok.

*edit. Garage says 2.2 bar should be about right and the 2.0 that the manual gives is deffo to low. So we'll see. Actually just wondering what they are at right now. Not used the sidewall bag of AT tires so pressure seems way low..

*edit2. Pressure was just 1.9 bar (27.5 PSI)! Pumped to 2.2 ( 32 PSI) now..

This is the best method.

My Land Cruiser runs 315/75-16, tips the scales at 6950lbs when Adventure Ready, and I run 35psi.

This is exectly the method I use. The only real way to know. I do this twice. Once unloaded, in my daily driver configuration. Then again loaded, with my Overland load. It changes a bit between loaded vs unloaded.

Tires loaded vs unloaded 5 to 10 PSI
Tyres loaded vs unloaded .3 to .7 bar
