Yeah, my TOD check light comes on after about 10 min of driving. I'm assuming it's because of my worn front tires.
BTW, it's also a good idea to check your tire pressure regularly. An unmonitored slow leak on one tire can send your TOD 'Wacko'. Even changes in the outside temperature can cause problems related to tire pressure (especially if you subscribe to Riff Raff's school of low unsprung weight & have really soft sidewalls).
Sorry Riff - Just Kidding - been a while since anyone has 'jerked yer chain'
