Tires pression

Tire pressure

Here's a subject that lends itself to much discussions, and everyone has their own miracle recipe. 

I'll give you my point of view, but it's up to you to make your own experiments and choose the pressure best suited to your vehicle and tire size.

My Jeep Wrangler is fitted with BF Goodrich All-Terrain T/A 285/70R17 tires and I'm very satisfied with their performance on sand, stones and on the paved road.

Let's come back to pressure: the principle is simple, a less-inflated tire will have a larger contact patch with the ground. 

The greater the contact area, the less the vehicle will sink into the ground (sand).

On a gravel track, a lower pressure will enable the tire to absorb shocks better, and the ride will be more comfortable. 

It's important to set the right pressure for the terrain, to avoid over-inflation and under-inflation, which can seriously damage your tires.

You'll also need to deflate and reinflate according to the nature of the ground, which means having a good compressor in your vehicle. 

Under-inflation will cause your tires to heat up, and you're guaranteed a flat tire.

On the road: 2.6bar

On the track: 2.4 - 2.2bar

On sand: 0.8bar or min. 0.5bar in case of sand stuck (10psi)

Remember : after deflating, reinflate as soon as possible when you find the paved road again!
