I have nitto trail grapplers, i feel like when I'm going over 30mph on a sharp curve my tires slipping brakes shake and the traction control light turns on....I had the same problem with my last tires so I was recommended to take out some air from the tires to 30-35 psi. I have put the nitto down to 30psi now it's a lil better but still a lil slipping. Any recommendations?

 

Don't take hard turns doing 30/mph with mud tires.

 

This is true, I have the same tires, on 17s. I can't whip around corners like I could with the stock setup. The ESP comes on if you go to fast which is using your brakes to slow you down.

 

What side wall you running? This is probably the biggest consideration. The larger the side wall the more tire flex you will get

 

I have Nitto Terra graplers and they corner beautifully at any speed.
I would wager you have a small lift and have not centered the steering since lifted. My rig did the same thing until I centered the steering.
Made a world of difference
Good luck..

 

x2 on this

 

This pretty much sums it up although I have the same tires and don't have problems with mine

 

I have the same issues with my duratracs. 32f and 29r I get the esp light often. I'm centered and still have it. I didn't when it was on stock arms and stock uncentered track bar. I figure learn how to drive it as a jeep, its not a car. if you lifted check your sway bar to check angle on it too. It may be off allowing more roll. Also check the rear never hurts.

 

I have 35/12.5/20r

 

Make sure steering wheel is dead centered.

Also, you may want to do the "Steering Wheel Dance" to turn off your traction control. I did.
