When I picked up my Disco, I noticed the tire pressure was at 50 in the rears and 44 in the fronts which they said were factory specs. I let some air out...40 in the rears and 36 in the fronts and the indicators came on that pressure was low. In the D I C settings it lists 2 modes. Heavy and light. Anyone know if I bring them to min in the light mode if the TPM's will not alert?

 

Put it in light mode and let a bit more of air out and you will love the ride even more.

 

Funny, exact opposite here, heavy mode at exact temps. Love the ride. Positive feel, not splashy.

 

Had to air mine down - the 22" just have too short of a sidewall for me on that high of pressure. Must be getting too old...

 

20s are more forgiving.

 

I had 22" on the Denali I just traded..They looked awesome....rode horrible. I have 20" on the disco...much better! I think the added unsprung weight of the rims and tires create havoc on any suspension...
