Vredstein Tyre Pressure

[x332race]

I have just fitted a set of Vredstein Quatrac 3s to my car. Vredstein's website recommend higher tyre pressures than those shown in the filler flap of my car...Which do I use....MB's or Vredstein's recommended pressures?

I see that, generally, Vredstein are recommending much higher pressures than MB for all their tyres...I must admit that I find the car feels better when the pressures are slightly higher on other makes of tyres, but not that high..

I thought the tyre pressure was dictated by the load carrying requirement? Hence MB publish pressures for a particular car front/rear. They don't specify the tyre. Stick with what is on the fuel flap.

Obviously the chosen tyre must have the correct load capacity / speed rating etc..

I wonder if that's the "fully loaded" figure which is always higher than the normal pressure. How do the figures compare to Mercedes "fully loaded" recommendations.

Higher for the front by 0.2bar and equal to the rear for Quatrac

Quite a bit higher than this for Sessantas...0.5 bar difference front and rear...

Guess I will set pressure slightly higher than recommended, as I usually do, and see where that gets me..

Also, if your car's handbook contains higher pressures for best economy, how do these compare with the tyre company's recommendations?

Interesting. Purchased and fitted some Vredestein Wintrac 4 Xtreme tyres last winter. Really happy with them. There was no information about pressures for my car on the Vredestein site. Prompted by this thread I’ve just had another look. Site now says 2.4 front and 2.7 rear ( bar) .

Mercedes data is 2.2 all round normal load, 2.2 front and 2.6 rear fully loaded.

Interesting that the MB normal load pressures are the same front and rear whereas the Vredestein are 0.3 bar different but don’t mention load.

Used them last winter at MB recommended pressures. I’ll pump them up a bit tomorrow and see if I can detect any difference.

Again if tyre pressures are related to load carrying capacity, I would expect the tyre manufacturer to recommend the highest pressure to cover all loads up to the recommended max. MB would have axle weights calculated for each model car so can recommend pressures to suit.

Hi

This seems to be a bit of a minefield with no common consensus.

Here is my post on a similar subject http://www.mbclub.co.uk/forums/wheels-tyres/60851-vredestein-sessanta-warning.html
If you get the difinitive answer please let me know.


Sessanta is a great gripping tyre btw, unmatched in the wet as far as i can gather.

Thanks,
