Hi! Just got my hands on a 64 plate Octavia SE Business Greenline 1.6 and am so far delighted.

 

A question - on the inside of the filler cap are three suggested tyre pressures. The usual "light load", "heavy load" and unusually for me an "Eco" pressure setting.

 

Can anyone advise what circumstances to use this and not to use this? Is it linked in anyway to the Eco driving mode on the Octavia?

 

Cheers

I'd suspect the eco pressure means a higher than normal pressure that reduces rolling resistance, but results in a harsher ride.

I would agree with the above comment. I normally run my summer tyres on the Heavy load pressure all the time (so effectively an ECO pressure when lightly loaded) & don't bother altering it when the car is fully loaded as that doesn't happen often.

 

Yes this gives me a harder / harsher ride (its hard to make the VRS any harder / harsher) but does give a slight improvement in MPG (not that I know what that is either) as  Ihave no time to work it out. 

 

If you are fitting winter tyres, it is advised to run them +0.2 to +0.4 bar above what the car manufacturer recommends for that size of tyre. The extra pressure opens up the Sipes in the tyres allowing for better winter condition performance.

This seems not to be universally agreed. Nokian recommends +0.2 bar in your winter tyres, but Michelin seems to recommend that you should run the same pressure in your winter tyres as your summer tyres. The Michelin caveat is that if you keep the car in a garage and measure the tyre pressure there you should add +0.2 bar due to the difference between the temperature inside the garage and outside, but if you measure the tyres outdoors and genuinely cold they state that vehicle manufacturers recommendation should be followed, as with the summers.

Pardon me, I was generalising it down some what. You are indeed correct so do as your tyre manufacturer recommends. They know a lot more than me!!

 

Tyre design will alter how much of an increase in pressure is advised (if at all) when running a winter over a summer hence why some manufacturers recommend one thing while others another. Tyre pressures are altered by the ambient temp, so a baseline level is indeed a good place to start. Your garage probably fits that bill just fine, then all you need as a well calibrated compressor and away you go!

Thank you guys. That's really helpful.

 

My Octavia Greenline is frugal enough so far, think going for the Eco setting may be a step too far!
