02 Stang w/ trac contrl prob

After shredding through the factory(goodyear ) tires for 40k miles i decided to get some new tires. bought some Yoko's same size same as the factory. look a little more low profile look to them. anyway because my 02 stang came with the slip differential it also came with the traction control. soo now when i get to about 40-50mph the traction control kicks and boggs down the engine. Boggs i mean takes any means necessary to slow down the engine. thinkn because i had run the goodyear down to almost metal i unhooked the battery to reset the computer, but to no avail still traction control kicks in around 40mph and doesnt let off at all. any suggestion on what may be the problem??
