I have my 2011Q5 for two months. It has 235/60R18 all-season tires. I measured the tire pressure first time yesterday when the tires are cold as the checking tire pressure light went on. Three tires out of four were around 43PSI. The rear right was just 35. I am kind of surprised that the factory setting (I assume it’s) is above the 32PSI printed on the sticker on the door jam. What tire pressure do you guys usually go by? Thanks!

 

You're running on "shipping" tire pressure, your dealer should adjust it after delivery - obviously was never done (they rarely do...) Manufacturer puts around 50 PSI for shipping to eliminate tire damage. My Tig had 48 PSI when delivered and first thing I have done is check and lower it to correct one.
Lower your tire pressure to 32-34PSI, your ride and handling will improve too, not to mention you will be running on correct PSI.

 

Tomashek got it right on. Always go with the label.

 

Thanks tomashek and warcity! Called the dealer to confirm. The tire pressure should be set to 36 PSI, although the sticker says 32 PSI.

 

I have all mine at 35, war/toma, think it would make a dif to lower that a bit (ie do you think you can notice the difference between 35 and 32)?

Also for winter do you guys usually run at a slightly lower or higher PSI?

Cheers

 

35 to 32 not much of q difference really. Fall, spring and summer I do 35 and winter I go to 33 always lower in colder weather. 33 is the recommended psi on the tag by the door. So far working good.

 

I agree with warcity, not much of a difference between 35-32 PSI. I also run on slightly lower PSI winter time. Generally recommended for colder weather.

 

I've had my 2011 Q5 for 1 month now and i've noticed the ride somewhat too firm. Feel every bump on the road. I bet it's because of the high pressure, going to check tonight. Thanks to all, will let you know.

 

rocca_ca: What was the result after you lowered your tire pressure? Did the ride improve?

 

MkIX - Actually, when I went to check the pressure, it was at 33psi which is about where it should be.

I guess the suspension was designed firm for good handling. I'm getting used to it.
