I was running 33 12.5 17 mud grapplers and had discount tire put 295/70/17 trail grapplers on and they have 40 psi and have been driving it for 2 days and light is still on?

 

was the light on when you took it in for tires? if so then sounds like a bad sensor.. If it wasn't on then maybe got damaged during tire change? they are easy to damage from what i hear.. I had a flat on mine.. swapped out the spare and light went out almost immediately so i don't think you should have a light especially after 2 day..

 

No light on when I came in to discount....the guys at discount kinda man handled my tires so..I'm going to call manager and see what can be done?

 

What year JK?
Did you swap sensors or get new ones?
Check the spare?

 

2009...didn't mess with sensors.just new tires. And now the tire pressure light is flashing after discount put there device on my tires to read sensors.....so I am assuming a bad sensor.
