2010 1500 2wd 4.8

I just recently put 285/70/17 and a 2in leveling kit in front and since then I've noticed that its like the transmission doesn't know what gear to be in and then today the stabilitrak service light came on fit the first time. When I restarted truck it was off. Did the increased tire size mess with something and is there any way to shut off the stabilitrak without havibg the traction control light remaining on? I really don't have any use for it
