2007 Trailblazer LT
I swapped my bruised and busted 17" Trailblazer rims & tires for a perfect set of Envoy rims & tires of the same size. Before this my dash indicator for tire pressure would flash for ages and then stay on. I didn't try to fix it as I knew I was gonna do the swap. Anyway, the tires were already on the Envoy rims when I got them and I do not know if they have sensors or what year truck they came off. But now the pressure light does not flash at all, ever, but the light does stay on constantly. What does that mean? No sensors in the new tires?
