Right now I have 40 psi for Tyre pressure but it feels a little stiff when cross over the bumper .. any advise?

 

Looks like you have an e-Hybrid also. There is a supplement to the manual for the e-Hybrid and it lists the tire pressure as: 34 PSI front and 42 rear for partial load. The full load listing is 37 front / 46 rear.

The above are for the 21" summer tires, which is what your picture illustrates. I have the same tires/wheels.

The e-hybrid manual is rather small and a quick read....lots of useful info in there.

 

I run 34 front/37 rear on 21" summer tires. The ride is best at those numbers

 

I think the Hybrid needs a few extra PSI in the rear due to it's 500lb battery under the cargo flow. Hence the higher PSI recommendation.

 

What does the driver's door jam say?

 

That's a lot of weight! Well there is the comfort psi; you can see it in the manual, and set it up to those figures.

 

I personally prefer a firmer ride so I set mine to Full Load. That's 42/46 psi.

 

thanks guys...
