Default Traction Control System Active

2007 base, put on new wheels and tires today. 305/35R19 rear and 265/45R18 front. All of the calculators I've used say they have the exact same diameter. Whenever I get up to ~70 mph the traction control active message will pop up on the display. Looking for help figuring out the cause. I assumed the tires were spinning at different speeds but with the exact same diameter they should be same speed. There is no check engine light.

Tires need to be staggered,not the same diameter.That is the issue.

In countless posts on the forum.I think a 4% difference is what the ebcm is happy with.A 265/40 would make it work.

Look at your door jamb. The stock sizes are printed there. Calculate the diameters. The rears are about 1.2" larger than the fronts, or about 104%.
