Hi all. 

 

When I got car 14plate Octavia estate, tyre pressure were set at about 24psi! 

 

I changed to the recommended light load (I usually have 2 adults, 2 kids) 2.4 bar all round (18" tdi). I noticed less crashing but feel a bit less "grip" more bounce! 

 

When going away I'd load the car with suitcases prob adding 60kg... I assume I wouldnt class that at fully loaded, 3.2 bar on the rear seems extreme?! 

 

So really my question, how much more should I increase for my "full load" and will reducing every day pressure by a couple psi give me a more stable feel? Or not to go below the diagram? 

2.4 bar is nearly 35 psi. That's a fair bit more than where you started driving the car at 24psi...

 

With 60kg loading in the back I wouldn't go above the lighter load recommendation of 2.4bar all round.

 

You could go as low as 2.2 but expect a little more squirm and worse economy. 2.2bar will ride the ridiculously pot holed and eroded and broken up surfaces called roads, by our county council, a little more compliantly, if yours are anything similar. 

 

Edit. The recommended pressures are on the high side but presumably based on engineering knowledge rather than a finger in the air. I think economy drives the min low load 2.4bar figures as well!
