It seems that ever since I put new tires on (265 60 18) which are a bit bigger then stocks, my TOD is engaging while driving on dry pavement on straightaway accelerations. The lights go all the way to the top and I can feel the TOD kicking in. It didn't use to do that. Once I get to speed, whichever speed it might (30, 55, etc) the TOD stays at just one dot lit up (normal I think).

Can just the tire change make it do this, or can it be a sign of something else going wrong?
