Now that most of us are putting on all-seasons or snow tires for the winter ,what pressures is everybody running? I put on Conti's the other day but haven't had a chance to do the chalk mark test yet.

Has anyone done this and is willing to post their optimal tire pressures at all four corners?

 

Regardless of the tire type, its best to follow your manufacture recom pressures. If that do not satisfy your driving style or comfort level, tune it in 2-4 pound intervals. Dont exceed the tires max psi.

So regardless of the sidewall strength, the tire pressures should remain what's printed by Mitsu in the door jamb?

I thought that a weaker sidewall would require a little more tire pressure for compensation. Sounds like I'm incorrect in my thinking.

 

You're right, a weaker tire needs more air pressure to support the same weight.
Use the manufacturer's recommended air pressure IF you get a tire with the same load rating.
If it has a lower load rating, you must increase the pressure for the tire to support the same load as the first tire.

 

If the tire has the same load rating, you should use the manufacture recommended pressures. Even on lower speed rated tires the inflation pressure should be the same, your not changing the amount of air the tire can hold. If you want to enhance the handling of the car, you can add more air. This will stiffen up the tire and allow it to respond a bit better. If you add to much air, the chances of irregular tire wear or impact damage will be higher. Just make sure you don't put too much in.

 

Sounds like I need to do the chalk test to optimize the tire pressures.

Has anyone done this with the Conti Extremes??
