Thread: 19" Maxxis AT Tyres

I am going to change my pressures to 36psi front & 38-40psi rear.

33psi front seems a little low and 36 rear the same ❓

I have always run my previous tyres 40psi highway pressure and due to the conflicting information on these 19" rims thought raising the pressure was a safe bet. Obviously not. :O

I run 34F / 38R on my Hankooks as I have found that to be a good set of pressure for on road use.

Hankooks here too.
35F 38R works well for me.

This afternoon I dropped the front to 36psi and the rear to 38psi.
Driving home M2 I didn't pay attention and didn't notice any difference until I got to my area (rural roads) where the roads are a little rougher and then noticed a substantial difference, the ride was so much smoother, it felt like I was still on the M2.

On anther topic,

i have often wondered if dropping tyre pressures also reduces wear and tear on the vehicles suspension?

Probably hard to quantify.

More to the point,would you have run similar pressures if loaded?

My vehicle is never lightly loaded

Fully loaded doing the Transcontinental I had pressures at the same numbers.

High pressures kill tyres on gibber. On the mine sites I was the person with the least punctures over the time I was there as I was the only one to air down...

I find it has benefit is when climbing..

I always air the nose down more, helps the front end pull a bit more.

You're absolutely correct.... and it's easily quantified.

I agree Tombie and assumed it was to achieve the same contact patch between front and rear axles.
The front axle is less loaded than rear axle, especially when at travelling weight. This is perhaps less of a factor if you have a bullbar and winch.
