Hi!

I bought my self a Mazda 3 for a week ago and been driving about 500 km ( 300 miles ) with a pressure that was 2.5 BAR on both front and back wheel ( this is what the car had when i bought it )
However the deck indicator warned me this weekend for the tire pressure so i did change the pressure on the back wheels to 2.7 BARs instead as the manual says it should be however i feel the car got more bumpy because of this and it drinks a tiny bit more fuel since then, been driving quite the same amount with the new tire pressure and on same kind of roads.

So my question is, what is the optimal tire pressure for 205/60 R16 i have winter wheels with spikes on them at the moment so maby there is a differance because of the spikes?

Sorry for my bad english but i hope u guys understand :)

According to the Dutch manual this should be 2,5bar for all the 16" wheels when the car has a normal load (max 3 adults). When fully loaded it recommends 2.8 for the front tyres and 3.2 for the back. For winter tyres it mentions 2.5 for front tyres and 2.7 in the back when the car has a normal load and when fully loaded it says 2.8 in the front and 3.2 in the back. When you have 92H or 92V winter tyres the back tyres should be even 3.4 with full load.

Spikes are not allowed in NL so can't help you with specific pressure for those.

Hope this helps, Ron.

Hälsningar från Finland! :wink2:

0,3 bar above recommendation should do the trick.

If you're getting pressure warnings, check your brakes for overheating, my right rear was jammed last thursday (third time in 160000 kms) and smelled and snapped when I pulled over. Pad fitting is too tight for Nordic conditions and they must be cleaned and greased periodically.

Ok kiitos :)
I will try to change the pressure on the front tyres also then and see if it helps.

I asked this very question to the tire shops around here (SW Colorado) and they all said to inflate the tires to normal pressure that is recommended by Mazda...doesn't matter the tire type or size...pressure rating is the same regardless...

Hej Jonne,
You can reset the tire pressure warning. So do 2,5 and reset it. It's simple and is in the manual.
