Winter tire Pressures

[np2004]

Just wanted to verify with others on this forum what tire pressures I should set my 08 4.8i with 19 inch all season Mich Latitude tires. I will check the manual at home but wanted some kind of average consensus on what others set their tire pressures at with similar tires.

Hi. I don't have the exact setup, (I have 18" Dunlop Grandtrek WT M3) and they are set at 32 psi for all 4.

32 psi will do fine.

Have you checked the door frame? I think your answer is there (for safety, anyway).

Obviously I know its in the Owners manual and on the inside door frame! I just wanted to know what the majority of owners set their tires pressures at during the winter from their own winter driving experiences and take an average. It's pretty clear the owners manual says change your oil at 15,000 miles but how many actually wait that long before you change it? Same concept the manual may say one thing but hearing what actual other owners do is another from their experiences.

Here is a TireRack article that makes the case for inflating 10-15% above 32psi in the winter.

I don't think you will have much of a problem if you keep them somewhere in that range (32-36 psi). I typically keep mine a tad above 32psi (measured "cold" ) year round since it only takes a couple weeks for them to drop 1-1.5 psi. The key is to check them regularly and make sure they don't drop below 30 psi.

I also would not recommend inflating (significantly) above 32 psi if you have harsh roads or potholes in your area. If you have smooth roads, have "perfomance" winter tires installed, and do a lot of highway driving...you might want to run them at ~35 psi and see if you notice a handling improvement on dry (albeit cold) roads.
