Lifted MK: Traction control.

Ok lifted MK fans, I am curious if any of you have had issues with your TCS warning lights after lifting. When I first lifted with stock tires I had zero issues. Then I mounted my 245/65R17's and that first two days were horrible. I had 30 PSI in the tires but could definitely feel the Jeep sway in some curves (yes I expected it due to the taller tire sidewalls). So I decided to add 2 more PSI to my tires to stiffen the sidewalls. Now for a couple of weeks I have had no issues until today when I took another route to work and crossed over a center lane that has a slight incline then a quick decline between the lanes. Now it never did it here or anywhere before but damned if the thing didn't go off again.

Also I have a friend with a Lifted Liberty and he has never had any issues but his is older and the TCS is different than ours. I also have a friend that has a lifted Commander and he says he has the same issue. he also showed me a company that makes a plugin computer that helps adjust the TCS of the lifted Commander.

But anyway I am rambling so I am just curious if anyone else has had any issues with TCS on a lifted MK.

Zero problems here. A little smaller tire, 235/60R18 (29.1").

I try to keep it at 35psi cold, but with the weather warming up it's been between 37 - 39 cold. I'll take it back down this weekend. I'm OK up to about 45 psi but it starts to act like an out of balance tire up around that pressure.

I think I'll stop by and add more air to the tires on the way home then... maybe I am just running enough and its allowing my sidewalls to flex too much.

I've tried to run them at 30 - 32 psi cold but if we have a cold snap and the pressure drops it sets off my TPMS. I've found at 35 it gives me enough leeway to avoid that.

I did initially have that issue too... but 32 seemed to be my magic number. When I mounted these tires the pressure gauge inside the bay read 32, but the truck only read 30 PSI (not sure which one is wrong honestly). So I just added the other 2 PSI and called it a day... But now this TCS alarm going off twice in two days. That has me a little irritated and worried at the same time. Like I said though I'll stop by the Gas station on the way home in a couple of hours and add some more... Who knows maybe that will help my gas mileage too...


...I'm trying to stay optimistic at this point.

I added some PSI tonight after work now I am 34 PSI cold, up from the 32 prior. Tomorrow on the way to work I'll try my alternate route to work and see if it goes off again.

since you're in Germany, maybe its the metric air that is confusing the monitors?

damn enter key posted the message.

Anyway reminds me of a good ol' Army joke that refers to summer air and winter air... In the early spring we would get the new Privates to let out all the air to put summer air in. :P

And that reminds me of one of my brothers telling my Mother that she had to change the factory air in her tires or it would void the warranty.
